本集《流言终结者》为您震撼呈现 On this shocking episode of Mythbusters,
本节目史上最具爆炸性的慢镜头 there's the most explosively epic high speeds in Mythbusters history,
亚当与杰米要去深挖 as Adam and Jamie dig the dirt
一个来自一战的流言 on a myth from World War I.
我们说要挖坑 When we say we're gonna be digging holes,
其实是指用这台机器挖 actually this thing's gonna be digging holes.
调整战壕的形状 Can the shape of a battlefield trench...
今天你在干嘛 What did you do today?
我给土喷了漆 I spray painted some dirt.
真的能减弱冲击波 提升士兵的存活率吗 ...really stop a shockwave and save a soldier's life?
这次是真的 This is for real.
倒数三 二 一 Three, two, one.
再见了 Bye-bye!
我觉得那里会留下个坑 I think there's gonna be a crater there.
另一方面 卡莉 格兰特和托里在扮小丑 Meanwhile, Kari, Grant, and Tory are clowning around.
我感到很傻 I just feel silly.
不明白为啥 I don't know why.
在一场喜剧性的车祸中 In a comedy car crash,
一堆气球 can a barrage of balloons...
托里 游戏时间到了 Tory, it's fun time!
能否起到安全气囊的作用呢 ...really aspire to be an alternative airbag,
还是这个流言是胡扯呢 or will this myth go pop?
准备 倒数三 二 一 Here we go, in three, two, one...

他们还将流言付诸实践 They put them to the test.
流言终结者 第十一季 第二集
引爆战壕
你就不会赞美下我这身装束吗 Aren't you gonna ask me about my costume?
不 Nope.
总之故事是这样的 I'm gonna tell you the story anyway.
流言来自于论坛 显然跟一战有关 It comes from the fansite and obviously it's from World War I.
你该不会要嘲笑我 Are you gonna make some kind of joke
在一战时还是个孩子吧 about me being a boy in World War I?
不会 我保证 No. I promise I won't.
流言说在一战中 The myth is that in World War I,
德国人在挖战壕时非常仔细 Germans were very precise about the digging of their trenches.
具体怎样呢 Towards what end?
他们认为当炮弹落到战壕中时 They thought when a mortar landed in the trench,
90度的拐角 the 90-degree corners
能有效阻止震波在战壕中的传播 would prevent the blast pressure wave from traveling too far in the trench.
他们严格要求拐角是尖的 They really were specific about it being sharp corners.
他们不要那种 They didn't want rounded corners
由于人走在走去磨出的圆拐角 that were worn away by people walking through.
非常尖的拐角 Sharp, sharp corners.
故事就是这样 That's the story.
挖土机和炸药 All right. Earth-moving equipment and explosives!
听起来不错 Sounds like a perfect day.
一战中的阵地战往往很惨烈 World war I's trench warfare was wretched,
但严谨设计的拐角 But could a carefully constructed corner
真的能提升士兵存活率吗 really have an impact on soldiers' survival?
这个流言本质与震波有关 It's a myth that shakes down to shockwaves.
劣质的拐角也许会让震波顺利传播 A clumsy corner will supposedly let a shockwave sail right past,
冲击波的传递
简易弯角
而直角拐角能阻止震波传播 while a perfect pitch will stop it dead.
90度直角
这个流言是真的吗 But will this myth hit the wall?
冲击波的传递 简易弯角 90度直角
怎么做呢 What's the plan?
我觉得这个流言 Well, I'm thinking absolutely this is a story
应该从小规模测试开始 that we want to start in small scale.
具体我想观察水波的传播 I'm thinking specifically using water ripples as our waves
在一些与我们说的战壕 and watching them move through environments
形状相同的容器中观察 that match the shape of the trenches that we're thinking about.
听着挺合理 That makes sense, and I tell you what,
咱们应该造个类似于波浪玩具的东西 why don't we make it like one of those wave machines, you know?
就是那种有一层油覆在带颜色的水上 The desktop toy that has oil over tinted water?
好主意 这样能减慢波速 Fantastic. That will slow down the reaction
也许我们能看清楚里面发生的一切 and hopefully we can see what's going on.
是的 Exactly.
因此超音速震波就要放到后面了 So, supersonic shockwaves we'll let rip later.
首先他们要用水来模拟流言场景 As the guys first dive into this myth with water.
流言讲的是不同形状的战壕 This whole story is about how different-shaped trenches
会怎样影响爆炸冲击波的传播 affect the propagation of blast pressures through those trenches.
我们想在工作室中先研究这些形状 And we want to investigate some of these shapes here in the shop
然后在进行大尺度测试 Before going full scale.
战壕的材料是透明塑料 We've decided to build our trenches out of clear acrylic,
里面倒满油和水 and we're going to fill them full of oil and water
以便观察波的传播 to watch the wave propagation.
很有趣吧 Isn't that cool?!
首先造一个长且直的 We're gonna build one long straight one.
虽然不好看但应该能用 It's not pretty, but it'll do.
然后我们要造一个阶梯型的 We're gonna build one that's, kind of, like a step.
真酷啊 Freaking sexy, man.
最后我们要造一个平滑的 And then we're gonna build one loosey goosey one
看看圆拐角的影响 to see what effect the round edges have
与方形拐角有什么不同 that's different than the sharp edges.
就是个这样子 That's how you are meant to be.
很好 Yes.
都做好了 It's all falling into place.
三个小型战壕都粘牢了 With the three tiny trenches bonded together,
开始注入液体 the filling can commence.
先加水 First with water,
然后倒入婴儿油 and then with baby oil.
这些是旧金山全部的婴儿油了 This is all the baby oil San Francisco had today.
要委屈某地方的婴儿了 Somewhere in the world, there's a lot of rough babies.
这个油 水和食用色素的组合 The tricky trio of oil, water, and food dye...
很酷吧 That looks cool, doesn't it?
应该能清晰反映出波的传播模式 should ensure that any wave propagation pattern is crystal clear.
我喜欢闻着像婴儿般的波浪 I like it when my waves smell like babies!
显然空气中的爆炸震波不是这个样子的 But what's also clear is that an explosion in air it ain't.
我们知道 Now before you get all up in arms
流言说的是爆炸震波 而我们小规模试验 about the fact that this myth is about blast-pressure waves
用的却是装了油和水的塑料盒 and we're doing a bunch of scale experiments
在指责我们犯错之前 with plex boxes and oil and water,
要知道波浪 please remember that an ocean wave...
荒岛生存之胶带大挑战S10E01
声波 a sound wave...
震碎玻璃的歌声S03E07
爆炸的冲击波 and a blast-pressure wave
爆炸遁逃S08E28
力学本质上差不多 are all effectively, mechanically the same thing.
打掉你的袜子S07E12
都是行波 They are a moving wave.
由于这个故事是关于 And since this whole story is about the idea
战壕形状能影响波的传播 that the shape of a trench can affect a wave,
我们认为这些小尺度实验是有效的 we consider these scale tests to be totally valid
与我们将在大尺度实验上看到的结果相似 and analogous to what we expect to see when we go full scale.
这个类比实验最后的要素 The final ingredient for this accurate analogy
是一个稳定的波源 is to create a consistent crest.
要想个办法让机器做这个 Now I've got to figure out a way to do this mechanically,
想到了 but I think I've got an idea.
亚当再次来到车间 So Adam hits the workshop once more,
把这个东西搞定了 and this time gets hammered.
在你说"去冲浪吧"之前 And before you can say "Surf's up,"
亚当已弄出了流畅的波浪 he's got waves as smooth as silk,
实验可以开始了 meaning the experiment can begin.
这是我们要的波 So, this is our impulse wave.
用来代替震波 It is our stand in for a shockwave.
这个装置能产生脉冲 The motor is giving an exactly perfect pulse
并且能传播到末尾 and delivering a wave that carries
一直到水槽的末端 all the way to the end of our tank
并拥有可测量的振幅 也就是高 with a measurable amplitude -- that is, a height.
我们现在所要做的就是把装置 Now what we're gonna do is put this rig
放在每个水槽中的相同位置 at the same exact orientation in each of our tank trenches
然后看看每个水槽 and see what effect their shape has
对其末端波的振幅有何影响 on the amplitude of the wave at the end.
准备好记录了吗 So are we ready to mark it down?
准备好了 先测量对照组的 Yeah. Let's get our control done.
灯光 Lights!
很酷吧 Isn't that cool?
开始了 Here we go.
随即 装置动了起来 On cue, the machine ripples into action
而亚当记录下来水槽末端 before Adam marks the waves' high and low points
波的最高和最低点 at the far end of the straight trench.
对照组非常成功 Our control was successful.
我们的波源装置提供了一个 Our wave-impulse machine gave us a wave height
在水槽末端从最高到最低点 from top to bottom at the end of the tank
约1.9厘米高的波 of three quarters of an inch.
现在我们想看看在直角水槽中 Now we want to find out if we get the same results
会不会有同样的结果 when we run this same test through a right-angle bend.
直角水槽中 油水混合物波浪实验 Oil and water wave test in a right-angle tank.
三 二 一 Three, two, one.
我立刻就觉得 Huh...Looks like a pretty clear result
结果非常明显了 just right off the top of my head.
这端比这端的振幅大很多 It's a lot larger on this end than it is on this one.
确实 很酷啊 Yeah. That is cool.
直角水槽看起来非常有效的 Our right-angle tank seems to be quite effective
减小了波的振幅 at reducing wave amplitude.
第一个拐角后 振幅减小了三分之二 After the first corner, it was reduced by two-thirds,
而第二个拐角后 减小了四分之三 and after the second corner, it was reduced by three-quarters.
效果很显著 That's significant.
是啊 等到波传递到水槽的末端 Yep, by the time the wave reaches the end of this tank,
它的振幅已显著地减小 its size has been severely slashed,
也就意味着直角 Meaning that the sharp corners
确实能够抵御冲击波 did shield their shockwave stand in.
圆角水槽 开始实验 Soft corners, here we come.
那圆角又会有怎样的结果呢 So, how will their curved corner compare?
开始 Go.
这头看起来大一点 It looks a little bigger down here.
看起来确实大一些 It does look a little bigger down there.
可能有结果了 We might have something.
仔细检查后 他们确实有了结果 And on closer inspection, they do.
这个实验 波的高度约0.63厘米 This test's wave height is a quarter of an inch --
圆角槽
比对照组的小 但是比直角水槽的大 Lower than the control, but higher than the sharp-turn tank.
圆角槽 对照组
所以 这对流言来说意味着什么 So, what does that mean for the myth?
圆角槽 对照组 直角槽
流言是在一战时 So the myth is that in World War I,
德国人修建的战壕有精确的90度角 Germans built their trenches on precise 90-degree angles
是因为他们相信那样可以降低在战壕中 on the assumption that it would limit the strength of shockwaves
冲击波的强度 traveling thorough the trenches.
在工作间里利用缩小版战壕 Our scale testing here in the shop
做了小尺度实验 with our small-scale trenches
测试了几种形状 in all the shapes that we've tried
证明他们的想法可能正确 seems to suggest that they might have been right.
在我们做过的小尺度实验中 This is one of my favorite scale experiments
这是我最喜欢的一个 we've ever done.
你有何想法 What do you think?
这个流言是关于冲击波的压力 Well, this story is about blast pressure.
-我们需要炸药 -肯定的 - We need explosives. - Absolutely.
这绝对是下一步的任务 That is definitely the next step:
挖些战壕 炸毁点东西 digging some trenches and blowing some stuff up.
我去换装 Yep. I'm gonna get a costume on.
好吧 Okay.
翻译：Wei 皇冠七彩 麦结 小饭
接下来 该吧小丑请出来了 Next up, it's time to call in the clowns.
派对气球对对碰
好了 我有个疯狂的流言 All right, I've got a crazy myth for you.
涉及到小丑和车祸 It involves clowns and car crashes.
两个小丑在开往一个派对 Two clowns are driving to a party.
坐在副驾驶的小丑有一堆气球 The clown in the passenger side has a big bunch of balloons.
接下来呢 车子失控发生车祸吗 What happens? They go out of control and crash the car?
完全正确 Exactly.
坐在驾驶席的小丑系了安全带 Now, the driver clown is wearing a seatbelt,
所以当车子撞到墙时 他没有事 So when they careen into a wall, he's fine,
但是副驾上的小丑没有系 but the passenger is not.
气球救了他一命吗 What, and the balloons save him?
是的 Exactly.
这是一个能上头条的流言 It's a myth that makes for one heck of a headline.
气球也能做安全气囊
但是一把派对气球 But can a bunch of party balloons
真的发挥安全气囊的作用吗 really act as an improvised airbag,
还是这个流言会破灭呢 or will this road-speed wipeout go pop?
好了 我们应该这样做 All right, this is what we should do.
我们应该撞两辆车 We should crash two cars.
先让它们以公路速度行驶 We'll have them traveling at road speeds
时速约56公里 of around 35 miles an hour,
第一辆车 看看没系安全带的乘客 And with the first car, we'll see what happens
会发生什么 to an un-seatbelted passenger.
很好 然后第二辆车 Great, and for the second one,
我们可以在副驾驶席上 we can put an average bunch of balloons
放一把普通的气球 in the passenger seat
然后看看G载荷会有什么变化 And see what that does to the g-loads.
好了 开工吧 Okay. Let's start clowning around.
我们测试的流言为 一把气球 So, we are testing the myth that a bunch of balloons
能在车祸中救小丑一命 will save a clown's life in a car crash.
我们会撞很多辆的车 Now, we are gonna be crashing a bunch of vehicles,
但在把小丑和气球放到车里前 but before we stick a clown and balloons in there,
我们要把那个变成一辆小丑车 we need to transform that into a clown car.
开工吧 Let's go to work.
根据警方的报告 According to police reports,
小丑们开了一辆很普通的车 the clowns were driving a run-of-the-mill runaround
就像这辆 like this,
我觉得很傻 I just feel silly.
我也不知为啥 I don't know why.
而不是一辆花花绿绿的派对车 albeit one that had been pimped for a party.
是的 就要个蓝圈圈 Yeah. It's a blue circle.
在托里完成他的作品后 And after Tory finishes his stripes and stars,
车子准备好开撞了 this car is ready to take the plunge.
小丑车准备完毕 So, the clown car is done.
该到精彩的部分了 Now it's time for the fun part.
我们要用吊车把车子吊起来 We're gonna take it up with the crane
车头朝下释放 and drop it straight on its nose,
和以时速56公里撞到墙的效果一样 as if it's crashing into a wall at 35 miles an hour,
然后测出他们承受了多大的力 and find out what kind of forces we're gonna get.
二元炸药之 汽车追尾引爆S09E15
竖直下落 The vertical drop...
哇 正中靶心 Whoa! Direct hit!
是个奇怪的撞车方法 is a curious way to crash cars,
危险驾驶S03E09
但是不会出现逃跑的车 but with no chance of a rogue runaway...
或是被压扁的围栏 or a flattened fence,
对碰之力再验证S08E06
不 不 不 不要 No, no, no, don't.
所以这是最可靠的方法了 it's the most reliable rig for a party-balloon pile up.
首先 我们要做对照组的实验 So, first up, we are gonna do a control test
驾驶员系了安全带而乘客没有 with the driver belted in and the passenger not belted in
看看我们得到的G载荷 and see what kind of g-loads we get.
要记住 这个测试里没有气球 Now, remember, there won't be any balloons in that test.
第二个测试 我们会用相同的方法 In the second test, we're gonna do the exact same thing,
只不过这次在乘客面前 but this time put a bunch of balloons
放了一把气球 看看会有什么区别 in front of the passenger and see what difference that makes.
而要达到目的 And do to just that,
他们首先要有两个小丑 The guys first need a couple of clowns,
着装完毕后 假人临阵以待 who, once dressed to kill...
我在让他笑 I'm making him smile.
被放进各自的车座中 are put into their respective hot seats
就像流言所描述 驾驶员系上了安全带 where just like the myth, the driver is buckled up,
而乘客没有 but his passenger is not.
为啥这小丑不系安全带呢 How come the clown wouldn't wear a seatbelt?
最后的步骤就是装上数据传感器 The final piece of the puzzle is to add the data sensors,
也就意味着该学术起来了 and that means it's time to get scientific.
我手里是一个加速度计 What I have here is an accelerometer.
我们会有两个 Now, we'll have two of them.
一个会装在小丑的头部和胸部 One will be attached to the clown's head and to the chest.
碰撞发生时 Now, when the crash happens,
会传输到数据记录器上 voltage will be sent to the data logger,
通过这种方式 我们能记录整个事件 and that way, we'll be able to record the event.
然后我们会查看数据 Then we'll look at the data later
看看小丑承受了多少g的载荷 and find out how many g's the clown endured.
可存活的G载荷必须低于100g A survivable g-load is anything under 100 g's.
这是我们的界定标准 That's our benchmark.
现在为了测量加速载荷 Now, to measure that,
我们要用加速度计 we have our PCB accelerometers
以及国家仪器公司的大卫来协助我们 and the help of our friend David from national instruments.
有了这些 就万事俱备了 And with that, everything's set for liftoff.
小丑出发 Send in the clowns.
我们装好了所有的传感器 We've got all of our sensors in place.
现在该吊起汽车了 Now it's time to raise the car.
开始咯 There we go.
我们钓起了好大一只啊 We caught a big one.
经过计算 如果我们把车吊起 We've calculated that if we raise the car 41 feet
保险杠到地面的距离为12米时 from the bumper to the ground,
就能模拟出时速为56公里的撞击 we can achieve a 35-mile-per-hour crash.
好了 现在是小丑撞车的对照测试 All right, this is clown car control test.
三 二 一 In three, two, one.
翻译：Nicole 不悛熊 SuSu
回到"引爆战壕" In "Trench torpedo,"
亚当和杰米的小尺度测试 Adam and Jamie's small-scale test...
这里看上去波幅更大一点 It looks a little bigger down here.
测试证明了直角能够阻挡水波传递 has shown that a sharp corner can stop a watery wave.
圆角槽=0.6厘米 直线槽=1.9厘米 直角槽=0.3厘米
这真是太酷了 This is really, really cool.
但如果是爆炸波的话会如何 But how about an explosive one?
水槽测试进行得很顺利 Well, that seemed to work pretty well.
也许有一些技术的问题 Maybe there is something to the technique.
对 我觉得是时候造几条真正的战壕 Yep, I think it's time to build some real trenches
用真正的炸药来测试了 and use some real explosives.
我们开始挖吧 Let's get digging.
好的 Okay.
为了挖出全尺寸的战壕 So, to dig the dirt on this myth full scale,
终结者们来到了一个老地方 the guys march to a memorable location.
我们今天在加利福尼亚的艾奥尼 We're in Ione, California, today,
我所站的地方 and I'm standing on the exact spot
就是我们测试"下水道之灾"流言的地方 where we actually tested the "Drain disaster" myth of all things.
下水道之灾S09E18
不过今天 我们要回来 Today, however, we're gonna go back in time
挖几条一战时期的战壕 and dig a bunch of World War I trenches
然后置它们于敌方炮火之下 and subject them to some enemy fire.
这一定会让杰米想起很多往事 It's gonna bring back a lot of memories for Jamie.
和他们在工作室的测试一样 Like in their shop tests,
终结者们准备挖三条战壕 the guys are gonna throw together three trenches.
一号战壕 Trench number one.
直线战壕 尖直角战壕 The straightaway, the rigid right angle,
和弯角战壕 and the shoddy serpentine.
看上去不错 That looks cool.
他们画好标记后 就可以开挖了 And once they're all marked up, the digging can go down.
多亏了这些重型机械 Where, thanks to some heavy machinery...
和加速时间的蒙太奇剪辑 and a time-lapsed montage,
3条15米长的战壕很快就挖好了 Their three 50-footers get sunk fast.
但这还不能说工作完成了 But that doesn't mean it's job done.
有很多人不知道 Not many people know this,
杰米的家里是油漆农民 but Jamie's family are color farmers.
多年来 他们一直像这样 They've been farming color like this
在户外制造油漆色板 on specially treated pieces of plywood
给特制的胶合板上漆 out in the fields for years.
以上都是我胡诌的 This is totally not true.
和事实没一毛钱关系 Not even a little bit.
事实上 我们用色板标记战壕 In fact, we are color-coding our trenches
能提供明确的实验顺序 也便于解释 so that both from a sequence and narrative standpoint,
你能很清楚的看出 某时是在哪个战壕实验 you can clearly see which trench we're doing at a given time,
但从实验性上来说 but also experimentally,
颜色标记能帮你区分不同的战壕 they'll help you separate them in your mind.
颜色标记令每条战壕都与众不同 The color coding does help tailor-make each tunnel...
非常笔直 It's coming along nicely.
也为战壕两边侧壁提供支撑 but the boards are also there to shore up the sides.
为什么要支撑两边侧壁 Why are we shoring up the sides?
准确说来 Well, really specifically,
这样战壕就能有完全笔直的边缘和直角 so that we get perfectly straight edges and precise corners
以供爆炸波传播 for our blast wave to move through.
这样我们就能测试流言的精髓 That's how we're going to assess the soul of this story.
当然 有一条战壕中的一部分 Of course, there's one part of one trench
不需要完全笔直的边缘 where strictly straight sides are not the order of the day.
这条圆角战壕 This one -- the imprecise corner trench --
我们在曲线圆角部分没有装胶合板 We are leaving uncovered with the wood on the curvy parts
以尽可能放大转角形状的区别 to get the biggest difference that we possibly can.
不过为了视觉上的统一 Also, for visual symmetry,
我们在侧壁上喷上蓝色油漆 We're gonna paint it blue to match the walls.
开始喷漆 Here we go.
亚当为蓝色油漆兴奋不已 Adam's tickled pink by the blue,
但更重要的是完成这项工作之后 but what's more important is that with that,
就该开始爆炸了 it's time to bring on the boom.
战壕挖好了 Our trenches are dug.
也做好了支撑 They're shored up.
甚至用颜色标记好了 Heck, they're even color coded.
现在可以爆破啦 Now, it's time for the explosives.
我们的对照测试会在这条战壕中进行 Our benchmark control test will be this trench --
15米长的笔直战壕 The 50-foot-long straight.
这能给我们一个直观的印象 It should give us a fantastic idea
即当爆炸波 of what happens to a blast wave
通过这个形状的战壕时会发生什么 as it travels through exactly this configuration.
当我们取得这组数据之后 And when we've got that data,
我们会在这条战壕做同样的测试 we're gonna do the same test in this one,
这是经典的德式直边直角的战壕 which is the classic german sharp-edged right-angle trench.
然后我们比较两组数据 And we'll compare the two.
最后 我们要在圆角战壕中 And finally, we'll be sending an explosive blast wave
测试爆炸波的传播 through our soft-cornered serpentine trench.
如果流言是真的 哪怕就一点点 And if there's anything to this story whatsoever,
那么我所站的地方所受到的冲击波 what we expect to see is a higher blast pressure
会比直角战壕中的 where I'm standing than in the corresponding spot
相同位置更大 in our hard-cornered trench.
好了 开始爆破啦 All right, let's bring on the explosions!
时间轴：海豚 by 校对：月月
小丑已经够犯愁了 It's enough to make a clown frown,
但派对气球真能在时速56公里的事故中 but can party balloons really save your life
保护你的生命吗 in a 35-mile-an-hour fender bender?
为了找出答案 终结者的对照测试车 To find out, the mythbusters control car
马上就要撞击地面了 is about to crash land.
准备好空投小丑汽车了吗 All right, are you ready to drop the clown car?
三 二 一 In three, two, one...
我觉得小丑们是活不成了 I don't think those clowns survived.
就肉眼来看 To the naked eye,
时速56公里的车头撞击看上去很恐怖 the 35-mile-an-hour head-on looks horrific.
但小丑能否幸存 完全取决于G载荷 But survival is all about the G-load,
如果G载荷超过100g Where anything over 100
小丑就难逃一死了 means there's been a clown catastrophe.
绑着安全带的驾驶员受到150g载荷 Now, the driver with seatbelt experienced 150 G's.
已经超过了致死标准 That's well over our benchmark for fatality.
更有意思的是 But even more interesting,
没有绑安全带也没有气囊的副驾驶员 the passenger that didn't have a seatbelt on or an airbag
胸前受到630g载荷 experienced 630 on the chest
胸口撞击强度
头部受到340g载荷 and 340 on the head.
胸口撞击强度 头部撞击强度
这是致命性的撞击 That is devastating.
等下测试 It's gonna be really interesting
气球能否产生影响 肯定非常有趣 to see if the balloons will have any impact on the numbers.
小丑汽车二号登场 So, cue clown car 2.
新的一天 新的小丑汽车 Another day, another clown car.
和对照测试一样 驾驶员小丑系安全带 Like the control test, the driver clown is buckled up
副驾驶员不系 while the passenger isn't.
这假发能吸收冲力吗 You think this wig absorbed any of the energy?
但和对照测试不同的是... But unlike the control test...
托里 游戏时间到了 Tory, it's fun time!
二号汽车会有流言中的气球屏障保护 Drop 2 will have the mythical balloon barrier.
是时候把气球赛进汽车里了 All right, now it's time to put the balloons in the car.
流言中说 Now, the theory here
这些气球会起到和安全气囊一样的作用 is these balloons are gonna act as an airbag.
安全气囊的作用原理 Now, the goal of any airbag
是在几分之一秒内 is to slow the passenger's forward motion
减缓副驾驶员向前的运动 as evenly as possible in just a fraction of a second.
我不确定这些气球能不能起一样的作用 I'm not sure these balloons are going to function that way,
但测试一下肯定很有趣 But it's sure gonna be fun to find out.
现在是装着气球的小丑汽车下落测试 All right, this is clown car drop with balloons.
准备好了吗 Are you ready?
好了 三 二 一 Okay, in three, two, one.
负一 Negative one!
看 真是精彩纷呈啊 Now, that is what I call a party.
不过我觉得他们还是难逃一死 I don't think they survived it, though.
这次冲撞仍然十分猛烈 Once again, the crash was a smash
乘客穿过气球屏障 as the passenger pushed past the balloon barrier
冲在了挡风玻璃上 and wiped out on the windshield.
好了 大卫 大家心里都有个大疑问 All right, Dave, the big question on everyone's mind --
气球能救小丑的命吗 Did the balloons save the clown's life?
第一次没有放气球时 Well, in the first drop with no balloons,
对照组
乘客头部要承受340g the passenger saw 340 g's at the head,
对照组 头部撞击强度
胸口所受冲击为630g 630 g's at the chest.
对照组 头部撞击强度 胸口撞击强度
而汽车放入气球后坠落时 And the drop with the balloons,
气球组
乘客脑部的载荷是350g The passenger saw 350 g's to the head,
气球组 头部撞击强度
胸口处为620g and 620 at the chest.
对照组 气球组 头部撞击强度 胸口撞击强度
结果几乎没有区别 So, the results are pretty much the same.
气球不能救他的命 The balloons didn't do anything for him.
几乎没什么差异 Almost no difference at all.
谢谢你的帮助 Thanks for your help.
快来 我给你看我的气球小动物 Come on, I'll show you my balloon animals.
结果证明 一束普通大小的派对气球 So, it turns out an average bunch of party balloons
根本无法在撞车时救你的命 Is not enough to save your life in a car crash,
但这并非不切实际的想法 But it's not such an outlandish idea.
气囊和气球都是充气物 An airbag is an inflatable, and so is a balloon.
也许有一种气球 Maybe there is a balloon out there
或者将气球进行特殊的排布后 or a configuration of balloons that we could make
就能在车祸中救你的命 that would save your life in a car wreck.
也就是说 流言也许是假的 In other words, the myth may be down,
但碰撞会继续进行 but burst it ain't.
在接下来的"引爆战壕"中 Coming right up in "Trench torpedo,"
高速镜头捕捉到了令人惊喜的画面 the high-speed shots that put the awe in awesome.
后期：zzzyusa 铭哥骑白马 总监：月月
欢迎回来 Welcome back.
这一整集 我们都在试图验证 All episode long, we've been testing a myth from World War I
源于第一次世界大战的流言 that a sharp-cornered trench is better in warfare
即作战时直角战壕比圆角战壕更有利 than a soft, rounded-corner trench
爆炸冲击波随着弹片传递 because it inhibits blast waves
而直角战壕能抑制 from traveling through the trenches
冲击波的传递 sent by exploding mortar shells.
我们现在要做标准尺寸的测试 We are now at the full-scale phase of this test,
我们在加州北部的黄金国 and we have a bunch of beautiful trenches out here
挖了几道漂亮的战壕 in gold country in northern California.
我们准备了些炸药 We have some explosives in our arsenal...
很好 Nice.
强力胶带的另一用途 Yet another use for duct tape.
很快 and any minute now,
我们就要以科学的名义来炸东西了 we're gonna start blowing some stuff up for science.
没错 但是第一步测试 Indeed, but for test one,
将先进行爆破 但不在战壕中 there will be a torpedo, but there won't be a trench.
就在这个地方 Right here in this very spot,
我们将引爆11千克的TNT炸药 shortly we'll be setting off 25 pounds of TNT
作为露天的对照测试 as our open air, unobstructed control test.
我们将每个3米放置一传感器 We've got sensors placed at 10-foot increments
因为在此之后 because shortly after that,
我们将在战壕中引爆炸药 we'll be setting off explosions in the trenches
收集对比相似的数据 and collecting and comparing similar data.
也就是说 露天爆炸 In other words, the open air blast
可以提供基准数值 should give the guys a bonus benchmark.
准备好了 Are you ready?
你来引爆吗 Are you the keymaster?
正是我 I am the keymaster!
Keymaster和Gozer均出自80年代电影《捉鬼敢死队》
你是老板 Are you gozer?
好的 伙计 I'm gozer, baby.
好了 开始吧 All right. Here we go.
地上爆炸倒计时三 二 一 Above ground blast in three, two, one.
我能感觉到呢 I could feel that.
像是一股持续时间很短的 That was like a refreshing breeze
让人为之一振的微风 that lasted a very short period of time.
这绝对会把人吓一跳 It sure was a refreshing flare up,
好消息是高速相机捕捉到了爆炸瞬间 and the good news is that the high speed's the bomb.
看看那个 Look at that.
那或许是我们用相机拍出的 Wow, that might be one of the prettiest ones
最美的画面之一 we've ever gotten on camera.
更好的消息是 他们得到了数据 But the better news is they got the data.
距离爆炸点6米处 20 feet from the blast
压强达到268.9千帕 and pressure was 39 pounds per square inch.
9米处压强为82.7千帕 30 feet, it was 12.
而到15米处 这一数字降到了34.5 And by 50 feet, it had dropped to just 5.
-直线战壕 -好的 - Straight trench. - Yep.
但将爆炸转移到地下后 But how will those numbers differ
这一数字又将发生怎样的变化呢 once the guys get down and dirty?
关于小丑车祸的流言 The myth of the clown car crash...
真是精彩纷呈啊 Now that is what I call a party.
目前看起来是无稽之谈 is so far looking like balloon baloney.
但那并非最终定论 But all is not lost.
好了 那法子不管用 All right, so that didn't work.
小丑直接穿过了气球 The clown pushed right through the balloons.
确实 但除了咱们测试的气球外 True, but there are other types of balloons
还有很多种气球 Than the ones that we tested.
看起来咱们该做点小尺寸的测试 Well, it sounds like we should do some small-scale tests.
或许咱们该选取一个重物 Maybe we should take a weight,
然后让其掉落在不同类型的气球上 drop it on different types of balloons
看看哪种气球的缓冲效果更好 and see which balloon decelerates the weight the best.
我喜欢 I like it.
目前 将气球转化为气囊的实验 So far, we haven't had any success at all
还尚未成功 with using balloons as airbags.
完全不达标 They just don't cut it.
我们现在需要做的是 观察气球 So what we need to do now is look at balloons
看看哪种气球缓冲效果最好 and find out which one absorbs the most energy,
为此 我要做一个气球撞击装置 And to do that, I'm going to build a balloon-crushing rig.
为了制作所述装置 And to rustle up said rig,
格兰特首先得做些巨大的金属环 Grant first wrestles up some giant metal rings,
谁要玩呼啦圈吗 Hula hoop anyone?
然后将其焊接连成管道状 which are then welded together into a tube,
这可是科学 It's science!
最后铺上一层塑料板 before being plastered with plastic.
-完成 -还有两件事要做 - Done. - Then just two things remain.
一个大小与管道直径吻合的木质圆盘 A wooden drop disc with a dead-on diameter.
很好 Good.
以及这个实验的原理解释 and an explanation of how on earth it works.
气球撞击装置完成了 So the balloon basher is finally finished.
我已经做好了有钢铁加固框架的 I've got my polycarbonate cylinder
聚碳酸酯圆筒 with the steel-reinforcing frame.
我在这个活塞上加了22.7千克的重物 I've added this plunger right here with the 50-pound weight.
我们要让这一装置落在各种类型的气球上 Now, the idea is that we drop this onto each type of balloon,
每次重物质量相同 using the same weight
气球的体积也相同 and the same volume of balloons each time.
然后进行对比 找出哪种气球 We can compare and find out which type of balloon
能吸收最多的能量 absorbs the most energy.
装置准备好之后 With the rig at the ready,
测试马上从对照组开始 the testing can tumble starting with the control.
开始吧 Here we go.
无气球对照组实验 This is control test with no balloons
倒计时三 二 一 in three, two, one.
好了 Okay.
好了 对照组是100g Okay, control is 100 g's.
-接下里 要放入气球 -8个 - Next, it's time to bring on the balloons. - 8...
先测他们之前用的气球 Beginning with the type from their earlier test.
15个充满气的乳胶气球 15 air-filled latex balloons.
倒计时三 二 一 In three, two, one.
很快 证明普通的乳胶气球 Immediately, it's clear that the regular latex balloons
对照组 普通乳胶气球
对于撞击 几乎不起任何缓冲作用 barely curtailed the crusher at all
加速计得到的数据几乎与对照组无异 as the accelerometer data almost matches the control.
现在我们将继续实验 看看哪种更好 Now we're gonna move on and see which is better --
不同材料 不同形状的气球 Different materials and different shapes like this.
把气球用得一干二净 接下来 With no balloon left behind, next up it's...
动物气球 Balloon animal!
为了保证对比的正确性 To ensure a correct comparison...
看那个 Look at that one.
一点也不奇葩 That's not a freak of nature at all.
圆筒中气球的高度要完全一致 the guys fill the cylinder to precisely the same depth.
我在做一只翼龙 I'm making a pterodactyl.
但他们的好奇之作 But will their curious creations...
这个不错 Oh, that's a good one.
对啊 这是个章鱼 Yeah. It's an octopus.
会缓和G载荷吗 lower the g-load at all?
动物气球倒计时 三 二 一 Balloon animals in three, two, one.
效果很好嘛 That worked pretty good.
比我想象的要好很多 That worked better than I thought it would.
这一招太棒了 This is really cool.
你看 G载荷从100降到了6 Look, it goes from 100 to 6.
-动物气的结果是6g吗 -是的 - We got 6 g's from the balloon animals? -Yeah.
普通乳胶气球 动物气球
G载荷减小了如此之多 With the g-load slashed so significantly,
动物气球是当之无愧的优胜者 balloon animals may yet be top dog.
但是接下来 But next it's...
小气球 Little balloons.
好吧 小型乳胶派对气球 All right, small latex party balloons.
太可爱了 They're so adorable.
三 二 一 Three, two, one.
伙计们 虽说个头小 但是很强大 They might be little, but, man, they do a good job!
托里说得对 Tory's right.
这些小东西的确很强大 These miniature marvels did such a good job
它们把G载荷降到2.8g that they cut the g's to just 2.8.
但接下来另一种派对气球会不会更加出色 But can that be bettered with the next party pitch?
大气球 Big balloon.
这些大个头的优势在于 The advantage of these bad boys
是由较厚的乳胶做的 is that they're made of a thicker latex,
这种材料应该能降低载荷 which could lower the load.
好的 大号派对气球 All right, giant party balloons.
倒计时 三 二 一 Here we go, in three, two, one.
天啊 过来看看这个 Oh, my god. Come look at this one.
看看这个超大气球效果如何 Look at the oversize one.
只有2g We've got 2.
大赢家终于出现啦 I think we have a winner!
-这看起来太不可思议了 -太棒了 - I know, isn't that crazy? -That's awesome!
现在我们要做完整规模的测验 So, now what we need to do is take this to full scale,
塞进汽车 高空坠落 fill up a car, drop it,
看看它能否救小丑一命 and see if it saves a clown's life.
派对开始啦 Yeah, now it's a party.
请勿在家尝试本片中的任何试验 Please don't try anything you're about to see at home.
我们就是你们所谓的专家 We're what you call experts.
倒计时 三 二 一 In three, two, one.
亚当和杰米的露天爆破 Adam and Jamie's open-air blast
制造了美丽诱人的蘑菇云 is beautifully done and dusted,
意味着 是时候潜入地下了 which means now, it's time to dig deeper.
就绑在这里了 We are tied in here.
第一个爆破的是对照战壕 First up is the control trench.
开始吧 Here we are.
15米的绿色直线战壕即将爆破 50 feet of green straightaway that's about to get rocked.
好的 All right.
直线战壕倒计时 三 二 一 Straight trench in three, two, one...
-噼里啪啦地往下掉 -是啊 - Things are falling. -Yeah.
好多东西从天上掉下来 Many things are falling from the sky.
太壮观了 That was spectacular.
雄伟壮观又让人毛骨悚然 Spectacular and spine-chilling.
直线战壕被彻底摧毁 Their straight and true trench has been well and truly trashed.
我们第一条战壕测试真真是 Well, our first trench test was --
我想我只能用破力十足这个词来形容 I think the word I'm going to use is gangbusters!
这次爆破的破坏力 The level of destruction is
真的远远超出我的想象 really shockingly higher than I would have expected.
火球本身 The fireball itself
窜得高度大概是地表上10米 reached almost 35 feet down this trench.
这实在是太恐怖了 It is -- it's horrifying.
太惊悚了 It's just horrifying.
喧嚣混乱的场面和高速飞舞的杂物 Both the hijinks and the high speed
都意味着此次爆破异常剧烈 suggest that the blast was harsh,
但是传感器的显示结果如何 But what do the PCB sensors say?
压力传感器测试到的爆破结果 Well, our pressure sensor data from the trench test
十分有趣 is very, very interesting.
编辑 帮我一个小忙 Editors, will you help me out?
画上两条线 Draw two lines.
很好 一条标战壕 另一条标地表 Fantastic. Label one "Trench" And one "Above ground."
战壕
地表
现在打上传感器结果 Now put down the sensor data that we got.
看见了吗 看见了吗 See that? See that?
战壕似乎 The trench seems to
有扩大冲击波的作用 have an amplifying effect on the shockwave.
战壕里爆破的冲击波远强于地表的 It's significantly higher in the trench than above ground.
那么 不同的战壕形状是否 Now, does the shape of the trench
对冲击波有不同的放大作用呢 affect that amplification?
这正是问题所在 对吧 Well, that's the question, isn't it?
在派对气球对对碰里 In "Party balloon pileup,"
我们比较得出了最佳气球 the guys now know the best-case balloon.
大赢家终于出现啦 I think we have winner!
车子对对碰又要拉开帷幕 So cue more car-crash carnage.
我们将以相同的方式实验 We're gonna run the test the exact same way.
两个小丑 We have our two clowns --
一个在副驾驶位子上 不系安全带 one in the passenger seat without a seatbelt,
一个在驾驶位上 系安全带 one in the driver seat with the seatbelt.
两个身上都绑有加速计 Both of them will have accelerometers attached to them.
我们将用起重机吊起车子 We're gonna take the car up with the crane,
将其从12.5米的高空落下 drop it from 41 feet
这样时速是56公里 so it's traveling at 35 miles an hour.
让它和地面相撞 Let it crash into the ground,
然后看这些气球是否会影响结果 and see if the balloons make a difference.
请记住 Remember,
在用普通乳胶气球时 with regular latex balloons,
小丑承受了620g载荷 the clowns peaked at 620 g's --
是致命载荷上限的六倍 six times over the lethal limit.
但是在此次试验中 But for this test,
我们不仅仅是用效果最佳的厚气球 the guys aren't just opting for their optimal thick balloons,
我想我爱上充气球的感觉了 I like to pump some helium every now and again. Yeah.
同时尽可能地多塞一点进去 they're also packing them in as tightly as possible.
我们以前全家旅游时 车就是这么塞的 This is like how we used to pack for family trips.
吊起来 Take her up.
我们正在把装满气球的小车吊起来 So, we're about to drop the clown with the balloons.
记住 我们的上限是100g载荷 Now, remember, our benchmark is 100 g's.
气球需要将G载荷降低到100g以下 We need to see the balloons decrease the g-load below that.
如果超过了100g If he goes over 100 g's,
小丑就会死 这个流言也将终结 the clown is dead and so is this myth.
这里是小丑车对对碰 All right, this is clown car drop
载着我们评出的最佳乳胶气球 With our best latex balloon.
倒计时 三 二 一 Here we go in three, two, one.
我的老天啊 Oh, my gosh!
我有预感会成功 I think it might have worked, man!
我预感小丑捡回了一条小命 I think that clown may have survived.
多么令人赏心悦目啊 What a beautiful sight.
小丑车从高空坠落到地面 I saw that clown car descending towards the earth,
之后我查看了慢镜头回放 and then I saw the high speed.
在慢镜头回放之中 Now, in the high speed,
你会看到汽车开始撞击地面 you actually see the car start to compact,
气球之间的缝隙 the balloons separate
刚刚好让小丑头部通过 just enough for a clown face to peek through
而小丑的鼻子碰到了挡风玻璃 and a clown nose to dust the windshield
只有又回到座位之上 and then start to go back into the car,
就好像那些气球把他弹回来一样 as if the balloons are bouncing him back.
拜伦 结果怎么样 All right, Byron, how'd we do?
有承受100g以下的吗 Did either guy get under 100 g's?
普通乳胶气球
之前的实验中 Now, you remember
用派对气球时 他承受的载荷超过600g he sustained over 600 g's with just the party balloons,
最大G载荷
但是这次只有130g But this time only 130.
普通乳胶气球 超大乳胶气球 最大G载荷 最大G载荷
超大气球的确在很大程度上缓解了G载荷 Wow! That is a huge reduction in the g-load,
但是130g载荷 But still, 130 g's to your body --
生存的可能性几乎为零 there is no way you're gonna survive that.
的确是很遗憾 Yeah, unfortunately,
这个流言还是被终结了 we're gonna have to call this one busted.
完全被终结 Totally busted.
有那么一下下 I thought for a second there
我还以为有希望呢 it had a glimmer of hope.
没有 还是完结了 Nope. Still dead.
就算是用我们的最佳气球 So it turns out even with our best balloon,
超大乳胶气球 the oversized latex balloon,
也不可能拯救小丑的生命 we were not able to save the clown's life,
所以这条流言被终止了 so this myth is busted,
但是我们不会止步于此 but we're not gonna stop there.
这可是《流言终结者》 This is "Mythbusters".
我们会将试验更进一步 It's time to ramp it up,
我们要回到工作间 so we're gonna go back to the shop
看看能不能设计出某种形态的气球堆 and see if we can come up with some kind of configuration of balloons
来救小丑一命 that could save the clown's life.
一 One.
之前在工作间进行的试验... In their earlier shop tests...
虽说个头小 但是很强大 They might be little, but, man, they do a good job!
流言小组对不同气球逐一进行了测试 the guys tested one balloon type at a time.
然而现在 到了自由设计时间 But now, it's anything goes.
开始干活吧 Get to work.
流言终结者闷头苦干 As the mythbusters go head-to-head
只为寻找能够救人一命的气球缓冲垫 in a quest to find the ultimate life-saving balloon barrier.
先来看看卡莉... First up is Kari...
气打得太足了 太足了 Too much. Too much.
她设计的缓冲垫简直是个 who's making what can only be described
整人玩具 一坐下就能听到放屁的声音
维也纳香肠式的放屁坐垫 as a wiener whoopee cushion.
兴许挺管用的呢 That might work.
这巨大的一团香肠状气球 This giant, massive weenie balloon
应该能够解决气球气囊的一些难题 should take care of a couple issues with the balloon airbag.
其一 它们缠在一起不易散开 One, they won't separate,
这样一来 当撞击发生时 so the clown can't push right through them
小丑的脑袋就没法从气球之间穿过 when he actually gets in the crash,
其二 这些气球都没有充满气 and two, they're all a little under-inflated,
所以它们不会在碰撞时炸裂 so that you can't pop them when he hits them.
再有 小丑老师曾教导我 Besides, my clown sensei once said,
"球多力量大" "One balloon weak. Many balloons strong."
与此同时 格兰特的设计思路 Meanwhile, Grant is also going for
也是"气球越多 G载荷越小" the "More means less" approach.
知道这是什么吗 You know what this is?
没错 That's right.
是个巨型的气泡垫 It's giant bubble wrap.
最后再来看看托里 Finally, there's Tory,
他要将各种气球结合 以求最佳效果 who's combining balloons for a real knockout.
我这个的效果一定是最好的 I think we've got a winner here.
是的 长官 Yes, sir.
我的气球气囊是这样设计的 All right, now what I'm going to do for my balloon airbag
用巨大的乳胶气球和铝箔气球 is take the giant latex balloons and the mylar balloon.
然后将两者组装成为一体 What I'm gonna do is incorporate the two.
我将乳胶气球塞入铝箔气球之中 I'm gonna stuff the mylar with the latex balloons
我这样做的意图在于 because one thing I want to do
将气球固定在铝箔中 is keep the balloons together inside the mylar
希望这样能够救小丑一命 and hopefully that'll save his life.
好了 谁先来 Okay, who's first?
女士优先吧 I say ladies first.
想看看特大号香肠放屁坐垫的威力吗 You want the weenie whopper whoopee to go first?
是啊 我们开始吧 Yeah, let's do it.
好的 Okay.
与上次一样 Just like last time,
卡莉将作品放入1.2米的标记线下方 Kari loads her design to the four-foot marker
并提起了重物 and then takes the plunge.
试验开始 倒计时三 二 一 Okay, here we go in three, two, one.
拜托 这也太逊了 Oh, come on. That was so delicate.
看上去还不错啊 Looked pretty good.
但与上一次不同的是 But unlike last time,
这次他们要将三个作品全部试验完后 they're not going to disclose the loads
再揭晓G载荷分别是多少 until each design has been dropped.
下一个 托里的四层夹心缓冲垫 Next up, Tory's four heart coronary design.
要是依我看 You know what I think?
我觉得它肯定会... I think it's gonna go...
好了 现在试验的是"夹心气球" All right, this is stuffed balloons.
倒计时三 二 一 Here we go in three, two, one.
效果真不赖 That looked really good.
是呀 Yeah.
最后上场的 Last, but not least,
是格兰特的气球缓冲垫 it's Grant's turn to go down.
准备好见证奇迹了吗 You guys ready for the magic?
好戏要开场了 Yeah, showtime.
倒计时三 二 一 In three, two, one.
尽管有两三个气球炸了 Oh, we got a couple of pops,
但是效果还不错... but hey --
好吧 也许不止两三个 maybe more than a couple.
我们去看看结果如何吧 All right. Let's see what we got.
与前两个试验一样 Like the two before it,
格兰特的作品效果也很不错 Grant's rig looked rigorous,
但究竟谁的作品能够问鼎呢 but who will come out on top?
记住 我们需要小于2g的数据 Okay, remember we're looking for a number under two g's,
那是之前大气球的标准 which is what our big balloons got.
我的缓冲垫 结果是3.8g My contraption was 3.8.
特大号香肠放屁垫
相当接近 但不完美 Close, but no cigar.
这个分数也很不错了 That's a pretty good score though.
不怎么样 你的是2.8g Not really. You got 2.8.
铝箔气球与大号乳胶气球组合
离2g更近了 Oh, closer.
而格兰特 你的是1.7g And Grant, you got 1.7!
气球气泡垫
太棒啦 Hey, that's great!
可以进行全尺寸试验了 Now to go full scale.
我们可有得忙了 Oh, we got some work to do.
这就是目前最理想的设计作品 So, this is our winning scenario.
能够将撞击时产生的冲击降至1.7g It reduced the impact energy to 1.7 g's.
我们下面要制作15到20个缓冲垫 Now what we need to do is make 15 or 20 of them
卡莉 托里 格兰特
再塞满车体内部 and stuff them into every part of the car
看看能不能救小丑一命 and see if it saves the clown.
接下来 On the other side of the break...
你还是不要看比较好 Probably better if you don't watch.
小丑遇到了大麻烦 there's clown chaos
而"引爆战壕"也进入高潮 and "Trench torpedo" hits paydirt.
永别了 Bye-bye!
这是要干什么 What's all this?
我要跟你决斗 I propose a duel.
你我二人 You, me,
每人一把彩弹枪 paintball gun each,
每人一个战壕 one trench each.
看谁先击中别人 Let's see who can land the first shot.
我去这边 I'm there.
杰米 准备好了吗 Jamie, are you ready?
我随时奉陪 I'm ready if you are.
那就开战吧 Let's do it.
我的心脏砰砰直跳 My heart is pounding.
停战吧 我的头部中弹了 Truce! I have a hit on my head.
我赢啦 战争结束了 I did it! The war is over.
之前验证"派对气球对对碰"的过程中 So far in our "Party balloon pileup" myth,
怎么做也挽救不了小丑乘客的性命 nothing has been able to save the clown passenger's life,
但我们不达目的誓不罢休 but we are in the business of extreme.
所以又发明了这个 That's why we have this.
我给它起了个名字 气球气泡垫 This is something I like to call balloon bubble wrap.
卡莉 托里 格兰特
在重物下坠试验中 It got the lowest g-load
它能将G载荷减到最小 of anything we tried in our drop tests.
既有节日气氛 又能救人一命 It's festive and protective.
但若车以56公里的时速触地 But will it be protective enough
这能否保证小丑的安全呢 in a 35-mile-an-hour head on?
你还是不要看比较好 Probably better if you don't watch.
他们将车子塞得满满当当 To find out, the guys stuffed the car
满得都要溢出来了 so it's literally fit to burst.
气球塞得简直像是沙丁鱼罐头 You guys are packed in there like sardines.
这回应该能行了 That ought to do it.
我们马上将要进行最后一次试验 Now, with this last and final test,
目标是让小丑承受的G载荷小于100g we're trying to get below 100 g's on our clown.
小于这个值 他才有生还的几率 That is our benchmark for survivability.
之前试验中发现的问题 We've addressed all the problems that we've experienced
我们都一一解决了 with all the other balloons.
我们将小气球粘在了塑料布上 We have small balloons on sheets of plastic.
这样小丑就不会从气球之间挤出来 That way, the clown can't push through the middle of balloons
而且就算一个小气球爆炸了 and if one little balloon breaks,
也不会空出一个大洞 it's not gonna create a big cavity
害得小丑撞在挡风玻璃上 where the clown can actually fall into the windshield.
这条流言能否成真 It's a souped-up solution
全看这个升级版的试验了 that's do or die for the myth.
如果这次也失败 就彻底终结了 If this doesn't work, nothing will.
好的 试验开始 All right. Here we go.
现在进行气泡垫试验 This is bubble wrap,
倒计时三 二 一 in three, two, one.
看起来不妙啊 It did not look good.
去看看"派对气球对对碰"的数据结果吧 Let's go check the data for the "Party Balloon Pileup."
在气球气泡垫的保护下 All right, so how did the clowns do
小丑的情况会怎样呢 with the balloon bubble wrap?
气球气泡垫
该乘客头部承受了220g Okay, so the passenger's head peaked at 220 g's
头部撞击强度
身体是230g and his body at 230 g's.
胸口撞击强度
小丑们承受的G载荷 Wow, so the clowns actually
气球气泡垫 超大乳胶气球 头部 头部 胸口 胸口
竟然比上个试验的还多 experienced a bigger g-load than the previous test.
所以说 派对气球 So, party balloons
并不能代替安全气囊和安全带 are not a substitute for airbags or seatbelts.
不要再胡闹了哦 Stop clowning around.
流言被终结
想知道我们为何使用这些方法 Want to know why we did what we did
而非其他方法来检验流言吗 And didn't do what we didn't?
请登录流言终结者官网后期节目板块 Log on to discovery.com/ mythbustersaftershow and find out.
倒数三... In three...
亚当和杰米所挖的直线战壕中 Adam and Jamie's straight trench torpedo...
传出了轰然巨响 has just gone off with a bang,
炸药爆炸 速度惊人 and as well as a sensational high speed,
试验结果也出人意料 it's blown up some surprising results.
引爆战壕数据结果
对比地面爆炸的数据结果 Surprising because when compared to the open-air control,
在直线战壕 It's clear that the straight trench
爆炸波的压力值明显上升 amplifies the blast pressure.
现在的问题是 是否加个转角 The question now is whether a corner
就能使压力值降低 can cause those numbers to drop down.
首先出场的是德国工程学的巅峰之作 And first up, it's the pinnacle of German engineering --
直角战壕 the sharp-sided trench.
这个就是流言中的战壕 This is the trench that this story is all about --
一个具有完美直角的战壕 the one with the sharp corners and right angles.
根据我们目前所了解一切 And based on everything we've seen so far,
可以推测当爆炸波经过所有拐角 by the time the blast wave gets to the end of this trench,
到达战壕尽头时 past all these corners,
压力值应该是很小的 it ought to be fairly small.
放下去 Going down.
为了验证杰米的推测和流言的真实性 To put Jamie's prediction and this myth to the test,
工作人员在战壕内安置了炸药包 the guys position the explosive package...
漂亮极了 Absolutely beauteous.
并做好了引爆准备 and then deploy for detonation.
你准备好了吗 Are you ready for this?
这次你来旁观 Are you gozer this time?
是的 操作手 I am, keymaster.
-好吧 -开始倒数吧 - All right. - Call it out.
纯直角战壕 Right angle sharp-cornered trench.
倒数三 二 一 In three, two, one.
我不知道 我还以为会像火山爆发一样呢 I don't know. I think there's gonna be a crater there.
我也是这么想的 I think there might be.
去看看吧 Let's go look at it.
再见了 黄砖路 It's goodbye yellow-brick road
一声巨响 战壕四分五裂 as the blast tears through their trench.
但就结果而言 But at ground zero,
高兴已经不足以描绘他们的心情了 to say the guys are happy is an understatement.
好家伙 快看啊 Wow. Dude, check that out.
我觉得这足以说明问题了 I think this tells pretty much the whole story
那边的板子完整无缺 'cause that's intact.
爆炸的威力到了那里就消失了 Everything up to that point is not.
正如你所见 这里是战壕尽头的安全区 As you can see, this is the safe end of the trench.
越往那边走就越危险 The further you go that way, the worse it gets.
爆炸时能量沿着战壕扩散 Now, most of the energy seemed to travel down the trench
但从拐角的损害程度可以推测出 and appears to have gotten absorbed by these corners
大部分的能量都被吸收了 based on how badly damaged they are.
当到达这里时 能量已所剩无几 By the time you got here, there's not so much energy left.
距离为6米时 压力值413千帕 At 20 feet, the psi was 60.
9米时 压力值为131千帕 At 30 feet, it was 19,
15米时 压力值仅为48千帕 And at 50 feet, it was just 7.
压力值在行进过程中急剧下降 A colossal contraction from their tunnel trench.
但流言中强调 But the myth says that
只有精准的直角才能减小冲击 only precise corners can shelter a shockwave,
为了找到答案 and to find out just that,
是时候该引起另一场夺魂大爆炸了 it's time to end with another breathtaking bang.
我们即将在另一条战壕里进行爆炸试验 We're about to send another blast through another trench,
此时我正处在巅峰对决的当口 and I'm standing right where the rubber meets the road
故事即将进入高潮 for this entire story.
精准完美的直角战壕 This is where we will compare
将和常规的 precision engineering versus
有磨损的圆角战壕一决雌雄 your normal wear and tear of a soft-cornered trench.
我觉得 I think --
直觉告诉我纯直角的效果会更好 my intuition tells me that the sharp corners are better
在这条战壕的末端 and that we'll see a higher blast pressure
探测到的压力值会偏高 at the end of this very trench.
但究竟怎样 炸过才知道 But only one way to find out.
在终级测试中 For the final time,
工作人员设置好传感器 the guys set up the PCB sensors...
它有点烤糊了 It's looking a little toasty.
安置炸药 position the projectile...
接着 There you go.
撤回到安全地带 and retreat to safety.
准备就绪 Here we go!
在这条蜿蜒的圆角战壕内 This is 25 pounds of explosives
引爆11公斤的炸药 in a serpentine, soft-cornered trench.
好戏要上场了 This is for real. This is for the money.
三 二 一 永别了 Three, two, one. Bye-bye!
又被震撼了 Never get used to that.
蜿蜒战壕爆发轰天巨响 The serpentine salvo was a blast.
而杰米 And for Jamie,
似乎从大爆炸的高速摄影录像中 it's the high-class high-speed
发现了了蛛丝马迹 that seems to tell the story.
编辑 请把直角战壕和圆角战壕的 Editors, let's pull up the high-speed footage
高速摄影爆炸录像放上来 of the square-cornered and round-cornered trench on split screen.
好的 Okay,
如果我们仔细观察两个战壕内 Now if we look at the fireballs
火球的运动情况 in these two different trenches,
我们可以看到在直角战壕内 we can see that in the square-cornered trench,
火球在第一个拐角处就停止移动了 the fireball stops moving just after the first corner.
然而 在圆角战壕中 However, in the round-cornered trench,
火球在停止移动之前 通过了 The fireball passes the first corner and the second corner
第一个和第二个拐角 before it stops moving.
从视觉上判断 Now, visually,
如果你此时置身于圆角战壕的末端 that tells me that you're gonna be in more trouble
后果恐怕会更严重些 at the end of the round-cornered trench.
从战壕末端的 And that's something that
毁坏程度来看 似乎确实如此 the damage at rock bottom seems to agree with.
破坏要更严重些 More destruction.
你好啊 Hello!
但数据又说明了什么呢 But what does the data dictate?
我们收集了很多有用的数据啊 Well, I think we got some good data.
是啊 可以回去好好分析一下 I think we did. Let's get back to the shop and crunch it.
好的 Okay.
这些数据说明了什么 What do the numbers say?
真高兴你问了 I'm glad you asked.
我特地准备了这个来做解释 I have prepared this to explain them.
不是吧 你做了个蛋糕 What, did you make a cake?
不是的 这是四次爆炸试验的模型 No! These are our four explosions,
这些数字是 and these numbers represent
我们获得的爆炸波压力数值 the blast pressures we got in those explosions.
好吧 是挺有意思的 Okay. This is interesting.
我可以看见在直线战壕中 Yeah, I can see that the straight trench
压力值大幅上升 almost looks like it is amplifying the pressures
数值高出地面爆炸 because they're almost 10 times as high
压力值近十倍 as the above-ground control test.
没错 再比较一下直角战壕 Absolutely. And check out the difference between
和蜿蜒的圆角战壕 the right-angle trench and the serpentine trench.
很明显圆角战壕的压力值 It's clear that the numbers in the serpentine trench
要高于纯直角战壕的 are higher than the ones in the right-angle trench.
我认为数值告诉我们这个流言是可信的 I think these numbers tell us that this myth is plausible.
是的 So it is.
有此可能 Plausible!
