事实上我们真的找到了一个细微的差别
The bullet in the air traveled 5% slower
与真空中的子弹相比
than its partner in the vacuum.
空气中的子弹速度慢了百分之五
That's not a big result,
这不是什么大发现
But it is also borne out in a tiny way
但我们也通过嵌入玻璃的子弹
by the bullets that we found embedded in the glass.
小小的证实了一下
The bullet in the vacuum made a slightly larger pressure ring
真空中的子弹比空气中的子弹在玻璃上
空气 18毫米
真空 22毫米
in the glass than the one in the air.
造成了的压环稍微大一些
It's a tiny difference, but an interesting one nonetheless.
这是很小的区别但也是个有趣的区别
We chose a revolver for this test,
在此次实验中我们选择左轮手♥枪♥
and you'll notice in the high-speed footage
当你观察慢镜头
that a fireball is created around the gun when it fires.
会发现开枪时有火球围绕着枪
Now, that's because of the gases
那是由从弹壳中释放出的气体
coming out of the cartridge to escape.
造成的
If you look at the vacuum,
在真空状态下
that fireball is much, much larger,
火球会大得多
and that is because a gas, when it's exposed to a vacuum,
那是因为一旦气体被释放到真空环境里
is going to expand more.
会飘散得更广
And that makes me think
这让我觉得
that if you had an explosion in space...
如果在太空发生了一场爆♥炸♥...
like you've seen in countless sci-fi movies,
就像你在无数科幻电影中所见
that explosion would be much larger
真空下的爆♥炸♥威力会比
than it would be under normal atmospheric pressure.
正常气压下的爆♥炸♥更大
So, the myth that guns cannot be fired
所以关于无法在真空环境中
within the vacuum of space?
开枪的流言
It's totally busted.
被终结了
Yeah. It's busted.
流言被终结了
Let's move on to the next gun myth. OK
让我们证实下一个枪♥支♥流言好
Up next, Tory sets his sights on the lights.
接下来托里把目光放到了灯上
All right, Tory. So, you brought us to the gun range.
托里你把我们带到了射击场
What's the myth?
是什么流言
Now, you've seen this in so many hollywood movies,
这一幕你们在许多好莱坞电影中都会看到
where somebody shoots out a neon sign
当有人朝霓虹灯开枪时
and sparks go flying everywhere, just like this.
就会火花四溅像这样
All right, so, that was pretty hollywood.
这可真有好莱坞范儿啊
Good old special effects.
很老的特效
We're gonna have to make some more neon signs.
我们要找来更多的霓虹灯
We gonna test one for real
一试真假
And get some real guns, and then we can shoot them.
找些真枪来我们可以射击
This is gonna be awesome.
真是太赞了
A hollywood downtown showdown
在好莱坞中的市区招牌
wouldn't be complete without obligatory neon-sign fireworks.
不会每一个上面都有霓虹灯
But is this light show a complete fiction?
但这火光真的只是科幻片的效果吗
Will it really fizz and spark without special-effects fakery?
没有特效它也真的会滋滋作响火花四溅吗
Now, the way they create sparks in the movies
在电影中若要营造火花四溅的效果
is by using a paintball gun and a paintball round
用的是一把彩弹枪和彩弹球
that has zirconium and an abrasive substance.
球里含有锆和磨蚀物
When they fire it through the gun
当它从枪里打出来
and it hits its target, it creates a spark.
击中目标时会产生火花
But we're gonna see if we can create a spark
我们要求证的是
without the help of special effects.
没有这种特效是否也能火花四溅
So, first up, Kari goes into the light...Store
首先卡莉去了一家灯具店
for a little light learning.
学点灯具知识
This is Shawna. She's gonna help me make a neon sign.
这位是肖娜她会指导我做一个霓虹灯
Now, a neon light is not that different from a fluorescent tube.
霓虹灯跟日光灯管没有太大的区别
You ready? Think so.
准备好了吗是的
A neon light uses high voltage
霓虹灯通过高电压
to propel a current through a tube
使电流流经
that's filled with low-pressure noble gases like neon,
充满低压氖气等惰性气体的玻璃管
which gives us that sort of orangeish-red glow.
发出类似橙红色的光
Different gases will give you different colors of light.
充入不同的气体会发出不同的光
Oh, my god, I love this. This is so cool.
天哪我爱上它了太酷了
Yep, it's physics fireworks.
借助物理性质产生的焰火
High voltage causes electrons to flow through the tube,
高电压会使电子流过管子
Bombarding the gas atoms.
轰击气体原子
The resulting energy is given off in the form of light,
产生的能量以光的形式散出
and the color, or wavelength, of that light,
而光的颜色或是波长
is specific to the gas in the tube.
是由管内的气体种类所决定的
It's gorgeous!
太漂亮了
And with her two themed neon signs sealed,
做好了两个主题鲜明的霓虹灯
Kari delivers them
卡莉把它们带回了
to a familiar and warranty-voiding location --
这个熟悉可以随意破坏的地方
The gun range.
练枪场
All right. Are you guys ready for this?
准备好大干一场了吗
Neon sign versus 9mm handguns?
霓虹灯对决9毫米手♥枪♥
Let's see if it sparks.
看看能否火花四溅
In three...
倒数三...
So, will the combination of high voltage,
通了高电压的
vacuum-sealed neon gas,
真空密封的氖气
Two...
二
and live ammo
遇上子弹
provide the spark the myth requires?
是否会产生流言中的火花呢
One.
一
Uh, no.
啥也没有
Well, we hit it, but no sparks like hollywood.
我们击中了但没有好莱坞电影里的火花四溅
No. It was absolutely nothing like the movies.
没错跟电影里完全不一样
A result...
结果...
Shotgun!
换散♥弹♥枪♥
That's double-busted.
再次被终结
It's for science.
为了科学
When the guys pull out the big guns...
他们架好枪之后
All right. We're hot!
我们准备好了
In three, two, one.
三二一
Get some! Whoo!
来吧
All right. It doesn't matter if you have a shotgun or a pistol.
好吧不管拿的是散♥弹♥枪♥还是手♥枪♥
You fire at a neon sign,
朝霓虹灯开枪的话
you're not gonna get the sparks
是不会像好莱坞电影那样
that you'd get in a hollywood movie.
有火花四溅的
Coming up on "Mythbusters"...
接下来《流言终结者》...
If you can't stand the heat, don't fry guns in the kitchen.
如果受不了酷热就不要在厨房♥里炸手♥枪♥
Let's go eat some gun.
我们去吃点枪吧
To give their neon nightmare one last shot...
再给霓虹灯最后一次机会...
We're gonna have to do something a little more...Mythbustery.
我们要做些有流言终结者特色的事
Kari, Grant, and Tory filled a new sign
卡莉格兰特和托里用极易燃的
with highly flammable hydrogen
氢气做了新的霓虹灯
and lit it with the worst wiring job possible.
用史上做工最差的导线连接
That's right, I've created several Jacob's ladders,
我做了几个雅各布导电天梯
which are just, basically, traveling arcs.
它们是最基本的导电原件
All right. We are hot!
我们准备好了
12,000 volts each. There are three of them.
一共三个天梯每个都加上了12000伏电压
In three... 36,000 volts.
三... 共36000伏
Two...
二...
If anything is going to ignite that flammable gas...
要是那些易燃气体被点着了
One. This is it.
一... 肯定是因为它
Fire!
开火
Despite the enriched set of circumstances,
尽管设置得如此特殊
Not one single spark sparked.
还是一点火花都没有
I know why they do it this way in the movies,
我算知道为什么电影里
with all the sparks and the flame --
要弄得火花四溅火焰熊熊了
Because in real life, it's boring!
因为实际情况太无聊了
You shoot a tube, and the tube just goes out.
击中了灯管它也只是爆了而已
But you know what? That's okay.
知道吗没关系
Hollywood, you keep doing what you do,
好莱坞你继续这么干吧
and we'll keep busting the myths.
我们会一直终结那些流言的
For the final round in the "Bullet baloney" chamber
"子弹怪谈"最后一个环节
comes a myth best served hot.
是一个滚烫的流言
Okay, we've got a story about a guy
有这么一个故事
running from the police
一个从餐厅后厨
through the back kitchen of a restaurant,
逃避警♥察♥追捕的人
when he decides to ditch his gun
