Don't try this at home.
请勿在家尝试
All right, to take this experiment
把这个实验的危险性
from "Go ahead, try it at home" to "Mythbusters" danger,
由"在家尝试"提高到"请勿模仿"
we're gonna use some lab grade components here.
我们要用到一些实验室级化学品
We have a higher concentration of hydrogen peroxide,
这里有浓度更高的过氧化氢
and for our catalyst, potassium iodide.
并且用碘化钾作催化剂
Now, these are much more caustic chemicals here,
这些化学品的腐蚀性更强
and the reaction is a lot more energetic.
产生的反应也更为剧烈
Okay, so take two,
第二次实验
but this is definitely a do not try at home.
不过这次千万不要在家尝试
One step back. Is it gonna get crazy?
退后一步场面会失控吗
Yeah? You about to drop some science on us?
会让我们大开眼界吗
You ready? Do it.
准备好了吗开始吧
Holy crap.
老天爷啊
What the heck?
活见鬼了
Much more energetic experiment.
反应更剧烈的实验
Look how hot it is.
瞧这东西温度多高
You can see the steam coming off.
都能看到蒸汽冒出来了
Yep, that's the kind of toothpaste an elephant would be proud of.
这种牙膏当真不负大象之名
But now we've seen the toothpaste,
我们已经见识过牙膏
didn't someone mention an exploding snake?
有没有人说起过爆裂猛蛇呢
Now, for the most part,
多数情况下
elephant toothpaste is the sort of experiment you can do at home.
大象牙膏可以在家尝试
This next one is a little bit different.
下一个有些不同
It's called explosive snake.
它叫做爆裂猛蛇
Now, the first part of it involves sugar,
首先实验需要糖
which, by itself, is innocuous.
就其本身来说这是无害的
The part that makes it different is the other half,
另一样成分才使实验变得不同
which is this -- sulfuric acid.
那就是硫酸
Look at that.
快看
Sulfuric acid is corrosive.
硫酸具有腐蚀性
It's caustic, and if you splash it on your skin,
腐蚀性很强一旦溅到皮肤上
you could get severe burns.
会严重灼伤皮肤
So, unfortunately, not the sort of thing
所以很遗憾这种东西
you want to try at home.
你是不会想在家尝试的
And to do this experiment,
要做这个实验
I think I'm gonna need a slightly different wardrobe.
我想我得准备一套略微不同的行头
Ah, that's better.
这就好多了
So, I've got an apron to protect my clothing.
我围上了围裙以保护衣服
Acid gloves should protect my hands,
戴上耐酸手套保护双手
and a face shield for my face.
并且用面罩保护脸部
Now it's time to mix up the elements.
现在该混合材料了
It's another do not try this at home,
又是个不能在家尝试的实验
but will it be explosive?
但会发生爆♥炸♥吗
Okay, so it's coming.
好了开始了
Actually, no.
其实不会爆♥炸♥
Okay, so what happened here?
这里怎么回事
Well, the acid interacts with the sugar
硫酸与糖发生反应
and breaks it down into its components,
糖被分解
releases water in the form of steam,
其中的水变成蒸汽释放出去
and it leaves behind carbon, which is what the snake is.
留下碳也就是实验中的蛇
Now, it's a very cool reaction,
反应效果很赞
but not necessarily all that explosive.
但是不一定会爆♥炸♥
I think in order to be explosive,
想要产生爆♥炸♥
it should be faster and more violent,
反应还得更快更猛烈
and I think I can find a reaction that does that.
我认为我能找到这么一种反应
So lab raider Imahara swaps out the sugar
实验室侵入者今原将糖
for a classified organic compound,
换成了某种机密的有机化合物
adds the sulfuric acid,
倒入硫酸
then brings a little heat to the equation.
再稍稍加热
But will this result in that explosive snake?
这会不会产生爆裂猛蛇呢
Watch it.
看好了
Okay, don't blink 'cause this can happen really fast.
别眨眼这速度非常快
Okay. This is it.
好开始了
No way! That's amazing.
不是吧太神奇了
It's an instantaneous process called de-ammonization.
这种瞬态过程被称为脱氨化
The sulfuric acid dehydrated the compound,
硫酸使得化合物脱水
leaving in its wake a flaky carbon snake.
留下一条脆弱的碳蛇尾迹
So, conclusion --
结论如下
Two explosive snakes by different means,
两种不同的爆裂猛蛇实验
but unfortunately because of the sulfuric acid,
很遗憾由于需要硫酸
you can't try either of them at home.
你都不能在家尝试
So while both myths are confirmed,
尽管两则流言都被证实了
unless you've got access to a lab tech
但除非你能接触到实验员
and lab grade materials,
拿到实验室级的材料
you can't try these at home.
不然你无法在家尝试
Meanwhile, back at metronome HQ...
同时让我们回到节拍器总部...
Every now and then, it sounds like they're getting together.
有时听起来好像同步了
Yeah.
是啊
I do think that they cross phases somehow,
我认为它们确实出现了节奏重合
but I think they may be in sequence,
不过可能是依次进行
but not in the correct position.
但是位置不确定
If you look down the line,
沿着这列看过去
there's no rhythm or reason to this.
里面没有节奏规律可言
It's a case of so far, not so good.
到目前为止还不太顺利
What you're about to see could be dangerous.
你即将看到的实验会有危险
We're trained professionals
我们是受过专业训练的专业人士
so, please, leave the myth busting to us.
所以请让我们来检验流言吧
And next, could this soda stunt do you harm?
接下来汽水特技会有危险吗
Next up is a story
接下来的实验
that should definitely never be tried at home
绝对不要在家
or anywhere else for that matter,
或者其他任何地方尝试
given that it's illegal in a bunch of states.
因为这在许多州是违法的
What's that?
什么实验
Dry-ice bombs.
干冰炸♥弹♥
Yep, well, exploding things is never a good idea to try,
对尝试爆♥炸♥可不是个好主意
so why is it we're tackling it on this show?
那我们为什么要在节目中研究这个呢
Because like it or not, people do try this at home.
因为不管怎么说人们的确会在家尝试
These things put out a tremendous bang.
这些东西会引起剧烈的爆♥炸♥
I think they also put out a tremendous bite.
我想还会带来惨痛的代价
That's what we want to look at.
所以我们要试试
So we want to find out just how dangerous they really are?
所以我们是要搞明白到底有多危险
Exactly.
没错
We're gonna look precisely at why
我们要用实践证明
you should not try dry-ice bombs at home.
为什么不能在家尝试干冰炸♥弹♥
This DIY device
这个自♥制♥装置
works on that old trapped pressure principle,
基于气体体积受限压力增大的原理制成
which the myth busters know can be both spectacular and lethal.
终结者们知道它效果惊人杀伤力十足
But just how lethal will these dry-ice bombs turn out to be?
但干冰炸♥弹♥到底有多大的杀伤力呢
To find out, Adam's got to set his cap first.
要得到答案亚当得先盖上盖子
The capping it and getting away is where the real danger is.
盖盖子以及逃离的时候最危险
I've seen these things go off as quickly as a few seconds,
我看过这些东西在几秒钟内瞬间爆♥炸♥
so I don't want to be anywhere near these things
所以当我们用高速相机捕捉画面
when we're trying to film them on high speed camera
评估损害的时候
and assess their damage.
我可不想靠近它们
That might work.
可能行
Now, we're gonna be conducting this test with bottles
我们要用不同的瓶子做实验
as different as this one and this one,
这个还有这个
but I need to put the caps on all of them,
我得给它们都盖上盖子
and my method is gonna be using this thing
我的办法是用这个
because it has a handy turning part out the front.
因为它的前端有个方便的旋转头
That's how we're gonna do it.
就这么干
Adam sorted the hands-free capping.
亚当找到了不用手盖瓶盖的方法
Put your forearm into that hole.
把你的小臂伸到洞里
But now Jamie needs to give this dry-ice combo a hand.
现在杰米要为干冰实验造双手
We want to find out exactly how dangerous this is
我们要搞明白
to somebody that might be holding onto it.
用手抓瓶子到底有多危险
Obviously, we're not gonna use our own hands for that,
显然不能用我们自己的手去试
So we're gonna need some artificial hands.
所以我们要做几只假手
Beauty.
漂亮
