So we built a second shed.
所以我们又建了另一个酿酒棚
Exactly the same as the first,
和之前的一模一样
except in this one,
只不过这次
we'll be investigating a totally different kind of explosion.
我们将研究另一种完全不同的爆♥炸♥
We'll have Jamie's still in here.
我们将安装杰米的蒸馏器
And we're gonna pop a leak in it.
并在上面钻孔
Now the hole on the middle of it will be a perfect leak.
酒精蒸气会从中间的洞漏出来
When we have what we consider -- enough vapor,
当漏出的蒸气足够多之后
we'll introduce an open flame.
我们将点燃明火
We considered this to be the highest percentage possibility
我们认为这是最有可能产生
of yielding the type of bye-bye shack fireball that we were looking for.
我们想要的"再见棚屋"大火球的方法
Well, that ought to do it.
应该没问题了
Heat there. Alcohol in there.
这里加热烈酒在里面
Alcohol vapor out here. Boom.
酒精蒸气从这里出来然后爆♥炸♥
Well, boom. So long as the moonshine to air ratio is right.
要想爆♥炸♥ 酒精和空气的比例必须合适
Alcohol vapor becomes flammable between
当酒精蒸气占到混合空气的
3% and 19% when combined with air.
3%至19%时气体可燃
The ideal ratio is 7% though.
理想浓度为7%
And that's what we're gonna be aiming for.
这也是我们所期望达到的目标
But the thing is
但问题是
our alcohol sensors are proving to be not so reliable.
我们的酒精传感器测得不够准
So what we gonna have to do is
所以我们采取的方法是
measure the oxygen content in the room.
测试房♥间内的氧含量
There's our sensor, right there.
这就是我们的传感器
Perfect.
棒极了
So we know that when we reach an oxygen concentration of about 19.5%,
所以当我们测到室内氧气浓度降低到19.5%
as opposed to its normal 20.9% in the atmosphere,
而非大气中通常的20.9%
we'll have our ideal 7% concentration of alcohol vapor
就说明酒精蒸气浓度达到了理想的7%
and that's going to give us our best shot.
这样就能达到最佳的爆♥炸♥效果了
And to ensure ignition,
为了确保点火
they're using their small scale technique.
他们采用了微缩实验时的点火方法
Time to soak our ignition source in lighter fluid.
现在要用打火机液浸透点火源
But that leaves one key question.
但有一个关键问题
How would this happen in the real world?
这种情况在现实生活中如何实现呢
Let's say our moonshiner is out of smokes
假设私酒贩子的烟抽光了
so he drives to town,
于是他开车去了镇上
leaving the still operating,
但是仍开着蒸馏器
not knowing that there's a leak in it.
却不知道蒸馏器漏气了
He comes back with his cigarettes, opens the door,
他叼着烟回来了打开门
lights one, and up she goes.
打火点烟然后棚屋被炸毁
My prediction here is pretty straight forward.
我的预测很直截了当
You know, I like the overalls.
知道吗我很喜欢工装裤
They make carrying him a lot more easier.
穿着工装裤让他搬起来方便多了
I think this thing's gonna go ka-blum.
我猜会发生大爆♥炸♥
I can't possiblely do it as loud as it will happen,
我学不出来到时候会有多大声
but I think the visual cue that is going ka-blum
但是我想我们会看到的大爆♥炸♥场面是
is that this entire house
整座房♥子
is going to leap five feet in the air.
会被炸飞1.5米高
Still's warming up.
蒸馏器开始加热
Now we wait.
现在就是等待了
The wait begins.
大家开始等待
But will this be the shining scenario that
但是这一次真能
finally brings the still house down?
把蒸馏屋华丽丽地炸飞吗
Starting oxygen reading is 20.9.
初始的氧含量读数是20.9
Our butter zone will be between 19.5 and 20.
爆♥炸♥浓度将在19.5至20之间
That's the explosive ratio.
那就是理想爆♥炸♥浓度
And inside the shack,
而在酿酒棚内
the oxygen level is slowly inching towards it.
氧含量正在缓慢地向它靠近
It's down to 20.3.
下降到了20.3了
We can't see the vapor,
我们看不见蒸气
but it apparently is displacing oxygen. 20.2.
但显然它正使氧气浓度下降 20.2了
The guys prepare to bide their time
大伙耐心等待着酒精蒸气
as the ethanol fumes fill their hut.
达到最佳爆♥炸♥浓度这一刻的到来
Wow. Things are happening in there.
里面好像发生了什么
Our feed over here is getting fuzzy.
我们这边的图像正在变模糊
But after just five minutes
但仅过了五分钟
the air to moonshine mixture hits their explosive goal.
酒精空气混合气体就达到了理想的爆点
It's 19.5.
到19.5了
All right. That's the ideal ratio. Shall we?
好了这就是理想浓度了开始吧
Yeah. Let's see what happens.
好的看看会发生什么
Okay. Here we go.
好的准备好
Moonshing still explosion.
非法酿酒蒸馏器爆♥炸♥
Well, ignition. We hope.
是点火希望是爆♥炸♥
In three, two, one.
三二一
That was an explosion.
是场大爆♥炸♥
That was beautiful.
真是美极了
Yep. The still huffed and puffed and blew the house down.
是的蒸馏器蒸汽咆哮将棚屋吹倒
That worked perfectly.
效果好极了
That worked absolutely perfectly. Let's go check out the damage.
相当好去看看破坏程度
Looks like the still is holding the building up.
看起来是蒸馏器在撑着屋子呢
I wouldn't have expected that.
我真是没想到
And it did blow apart the building
爆♥炸♥确实摧毁了酿酒棚
as well as lift it off the foundation.
甚至都把它炸飞了
It did, but not five feet like I predicted.
确实但没有我预测的1.5米
More like one foot.
也就30厘米
Well, that was as awesome
这次实验非常棒
as our first experiment was disappointing.
之前的实验结果着实令人失望
We actually got a ka-blum, a genuine whoof,
爆♥炸♥成功了就听到"呼"的一声
and the failure of our entire structure.
然后整个酿酒棚就散架了
The only thing holding this building up at this point
而此时唯一的支撑
is the still that's inside it.
就只有里面的蒸馏器了
What's interesting though to me is that we didn't see a thing.
我觉得有趣的是我们什么也没有看见
That room was not cloudy.
屋里并没有气雾
There was nothing like any kind of teapot steam
和我所期待的用茶壶烧水时
coming out of the nozzle which I kind of expected.
水蒸气从壶嘴中喷出的情况完全不同
So, you know, if you're a moonshiner and then
所以假如你是一名私酒贩子
you opened that door,
你打开那扇门
you wouldn't have any idea what was going on
直到悲剧发生的那一刻
until it was too late.
可能都不知道是怎么回事
Which means clearly this leaky still scenario is confirmed.
这意味着蒸馏器漏气爆♥炸♥的流言被证实了
So what does this tell us?
那我们有什么收获呢
Well, I think first and foremost we learned
我觉得首先就是
that a home built still
自♥制♥的蒸馏器
is not a destructive pressure vessel make.
并非危险的高压器皿
Yes, but a leak in a still can create enough fumes
是的但是从蒸馏器缝隙漏出的蒸气
to blow a building apart.
足以把房♥子炸飞
Yeah.
是的
Making moonshine is a dangerous business.
私酿烈酒是一件很危险的事
We ain't even started drinking it yet.
我们都没来得及喝呢
Let's remedy that.
那现在喝吧
Every single thing we investigate on "Mythbusters"
我们在《流言终结者》中进行的每个实验
has to do with the transfer of energy.
都与能量转换有关
From one state to another, from one form to another,
状态的变化形态的变化
from one place to another,
位置的变化
often rapidly and hopefully with disastrous results.
速度极快还可能伴有灾难性后果
So just check this out
看看这个
and watch how the rapid combustion
酿酒棚中酒精蒸气的
of all the alcohol fumes in the shack
燃烧速度何其之快
causes it to expand.
使其膨胀
The in-rush of oxygen causes fire to just appear almost everywhere.
涌入的氧气使火焰几乎在房♥间里四处蔓延
The corona of flame around the perimeter
火的外焰
as the atmosphere is combining with the oxygen and the gas fumes
随着空气中氧气和酒精蒸气的混合
in order to set everything on fire
把一切都点燃了
as well as total destruction of the shed.
同时摧毁了整个酿酒棚
This is the best part of the job.
这是最赞的部分
Thunderhill.
雷霆崖赛道
Brings back memories, huh?
勾起了回忆吧
You're going down, sucker. You're gonna have to catch me.
小样你输定了来抓我啊
We are back at thunderhill.
我们又来到了雷霆崖赛道
The same place where we tested indycar myths.
我们曾在此地验证印地赛车的流言
