A good hit, but still no fireworks.
干得不错可仍然没有一丝火光
The primer's dented,
底火都被撞凹陷了
but it wasn't enough to set off the shotgun shell.
还是没能使霰弹发射出去
But the team isn't ready to give up just yet.
但这支队伍仍不准备放弃
In keeping with the Macgyver-like myth,
为了继续进行这个运用普通物品逃生的流言
they're going to improvise.
他们准备自行发挥了
So, there's one last possible scenario
还有最后一种方案可能证实
that's in the realm of reality.
这个流言是可信的
Say they found a little sharp piece of metal,
假如他们发现了一小块尖锐的金属
or a screw, or a nail, or something from the plane...
或者螺丝钉子等飞机上的什么东西
Ready to nail it?
准备好搞定这个流言了吗
and then used that to try to hit the primer.
然后他们试图用这个来碰撞底火
Here we go, in three... two--
开始了三二
It's kind of like playing pool One.
有点像打桌球一
It worked! It worked!
成功了成功了
Yes!
太棒了
Just like it says on the tin, the boomstick went "boom".
正如电视中所展现的棍枪开火了
Groovy.
太棒了
But did it do any damage?
但它有没有造成伤害呢
It didn't make it, actually, through the fake fur.
事实上它没能穿透假皮
Without the gun barrel to contain the blast,
没有枪管来引导霰弹的爆♥炸♥
the energy disperses, and the ballistics gel is unscathed.
能量就分散了弹道凝胶丝毫无损
So, for protection from the pack,
因此如要从兽群中逃生
save time and stick to a pointy stick.
省省时间拿上一根尖锐的木棍就好
I mean, if I had a choice,
如果可以选择的话
I would have gone with just the plain spear,
我会用一根简单的长矛
because this is just going to make him angry.
因为这只会让他发怒
The spear might actually kill him.
而长矛还有可能杀死它
Spear's a great weapon.
长矛是很棒的武器
It's worked for thousands of years.
千百年来它都很有用
Busted.
流言被终结了
Busted. Busted.
终结了终结了
Do not try what you are about to see at home.
请勿在家尝试本片中的任何实验
We are what you call experts.
我们就是你们所说的专家
Next up, Adam and Jamie hit the ballistics bunker
接下来亚当和杰米射击弹道仓
for a physics and fiction face-off... in space.
挑战小说中出现过的物理问题太空对峙
Dude, I think we should test how much of a deterrent...
伙计我觉得我们应该测试这个声音的
that sound is.
威慑力有多强
It's pretty distinctive. Totally.
很有特色绝对
So, what's next?
接下来我们要做什么
Well, apparently,
很显然
it is impossible to fire a gun in space.
我们没法去太空中开枪
You mean, like, in a vacuum?
你是说在真空状态下吗
Exactly. Think we've got to test it.
正是如此我认为我们得实验一下
I've always wanted to go to space.
我一直很想去太空看看
Me, too! Guns in space? What could possibly go wrong?
我也是太空枪击能出什么乱子
Look out!
小心
Although Hollywood would have us believe otherwise,
尽管好莱坞可能会让我们相信会出乱子
the prevailing theory is that a gun will fail
但理论说枪在太空中开不了火
to fire in space for two reasons.
有两个原因
First, the lack of air and atmospheric pressure
首先由于太空中没有空气和气压
in the vacuum of space may cause the slug to deform.
也许会造成重弹头变形
Second, without oxygen,
第二没有氧气的话
the primer can't ignite the propellant.
点火器不能引燃弹♥药♥
And, to test these theories,
为了检验这些原理
Adam and Jamie need to fire a gun in space
亚当和杰米得在地球上
down here on earth.
模拟太空开枪
That looks good. It's gonna be beautiful.
看起来不错效果会很好的
To do that, they're building a bulletproof vacuum chamber.
为此他们制♥造♥了一个防弹的真空箱
And, once Jamie inserts a pressure gauge,
一旦杰米装入一个测压表
Their soon-to-be-sealed chamber is ready to have
他们就有了一个即将被密封的箱罐
all of its air removed -- every single atom.
一丝一毫的空气都被抽走了
But first, a test fire.
但首先测试火力
This is a real pistol,
这是一支真枪
and we're about to fire it in our shop.
我们将在我们的工作室里开枪
Now, setting up a gun to be fired by a remote control
置入手♥枪♥ 用远程设置扣扳机
Is always fraught with some dangers,
这仍然有危险
and we are removing those dangers in the following way.
我们用以下方法消除危险
One, our entire vacuum chamber is made
首先我们整个真空箱
of bullet-resistant plastic.
是由防弹材料制成的
Two, we have an extra piece of bullet-resistant plastic
第二在子弹对准的箱子另一头
at the end of this chamber for the bullet to land in.
多加了一块防弹材料
Three, we're gonna have a piece of steel
第三在外加的防弹材料后面
behind that extra piece of bullet-resistant plastic.
我们又加了一片钢板
Four, our gun is mounted firmly
第四手♥枪♥牢牢地装在一个
in a gun rest meant to hold it.
可以固定住它的托上
Five, we are only using one bullet.
第五我们只用一枚子弹
All right. Jamie, I'm ready to load.
好的杰米我准备上膛了
Are you ready? I'm ready.
准备好了吗准备好了
There's a couple of others, but they don't really matter.
有些其他的因素但并不重要
Before we pull the trigger on this gun in a vacuum,
在你在这个真空箱中扣下扳机前
we're gonna fire the gun in the vacuum chamber without a vacuum
我们要在这个非真空的密封箱中开一枪
to be able to compare the two.
用做对比
In three, two, one.
三二一
There it goes.
搞定
That was a bang.
清脆的一枪
Well, seemed to work pretty well.
看来进展很顺利
Indeed.
是的
Yep, they've tested the remote-firing mechanism,
他们对远程射击装置做了实验
Captured it on high-speed,
高速摄像机拍到了这一幕
and have a slug impact on the backboard to compare.
并放出慢镜头回放做出对比
It's time to reload...
又到了上膛的时间了...
Gun is hot. Range is hot.
来吧趁热打铁
and suck some air.
抽出些空气
And Adam, for one, is confident
亚当信心十足
That in this instance, hollywood has it right.
实验可证好莱坞没有胡编乱造
We're waiting for our vacuum chamber to come up to a full vacuum,
我们在等着真空箱变得完全真空
and then we're gonna pull the trigger on our revolver,
然后我们扣下左轮手♥枪♥的扳机
And I am here to tell you
我敢跟你们说
that I think it's gonna go "Bang."
一会儿肯定会有"嘣"的一声
I don't think the vacuum's gonna have any effect
我觉得真空对于枪内火♥药♥
on the gunpowder's ability to propel the bullet
推动子弹发射出枪筒
out the barrel of our revolver.
不会有任何影响
This is it. With the chamber evacuated to a full vacuum...
是时候了密封箱完全真空了
Are you ready? I'm ready.
准备好了吗准备好了
and Adam's remote finger on the trigger...
远程遥控也准备好了
All right. Here we go.
好的开始吧
will hollywood have its day,
是好莱坞大获全胜
or, as the myth suggests, will the gun misfire?
还是像流言推测的枪会哑火
Firing a gun in a vacuum.
在真空环境中开枪
Three, two, one.
三二一
There it is. There it is.
成了成了
Successfully shot.
成功射出
That gun fired in a vacuum!
枪在真空中发射啦
It did.
它做到了
The images are spectacular
场面壮观
and the details fascinating.
细节也很有趣
I swear, if I just saw this footage,
我发誓要是我只是看慢镜头
I would totally believe that it was a special effect.
我肯定觉得这是特效
It doesn't look real.
看起来好不真实
Amazing.
好惊人
真空
But exactly what happened?
但到底是怎么一回事呢
Cue forensic duo doctors Hyneman and Savage.
听肥瘦双博士来给我们慢慢讲解吧
Now that we know a gun can fire in a vacuum,
我们可以得知真空状态下可以开枪
The question arises, does the bullet behave
问题是在真空中运转的子弹
any differently in the vacuum than in the air?
跟在空气中运转的有何不同
We might posit that the bullet would move slower in the air
假设真空中的子弹飞得更慢
Because the air provides resistance,
因为空气有阻力
where the vacuum provides none.
而真空中没有阻力
And, in fact, we did find a very minor difference.
