that's pretty good.
这已经很不错了
Not just pretty good.
不仅是很不错
The team successfully fired a cannon made of water.
这支队伍成功的发射了用水制成的大炮
But according to their strict criteria,
但以他们严格的标准而言
It's not yet successful.
这还不算成功
Well, I know the cannonball made it all the way to the guys,
我知道这枚炮弹能直达那些人站的位置
but I'm hoping this time, it actually does some damage.
但我希望这次它能制♥造♥点伤害
So when you're talking about the damage
当说起一枚炮弹
that a cannonball can cause,
能造成的伤害时
you're talking about kinetic energy.
其中最重要的就是动能
Kinetic energy depends on two things, mass and velocity.
动能取决于两个因素质量和速度
Now, the mass is determined by the ball itself.
质量取决于炮弹本身
So if we want more kinetic energy,
因此如果我们希望有更多动能
what we need to do is increase the velocity.
我们需要做的就是加快速度
Now, under normal circumstances,
现在在正常情况下
all you'd need to do is add more black powder,
你要做的就是加入更多的黑火♥药♥
and it comes out faster.
它发射时就会更快了
But the more black powder we put in,
但如果我们放入更多的黑火♥药♥
the greater risk of destroying the cannon itself
大炮就更有可能在造成致命伤害前
before we get a lethal shot.
自己土崩瓦解了
So with the same amount of black powder
现在加入等量的黑火♥药♥
and a tweaked trajectory...
并将弹道扭转
We are hot.
我们好激动
will the ice-cold cannon this time
这一次冰冷的大炮
be an ice-cold killer?
能化身冷酷的杀手吗
This is the ice cannon, in three, two, one!
冰制大炮倒数三二一
The answer is... no.
答案是否定的
Although the ball more than covered the distance,
尽管这次炮弹发射涵盖的距离更长
sailing over the heads of the targets,
直接从靶子头上飞过
this myth is on the rocks.
这个流言还是触礁了
I like this.
我喜欢这个
I'm gonna start crushing my ice this way.
我以后就要这么弄碎我的冰块
Mixing fire and ice
火与冰的结合
was never likely to be a dangerous cocktail.
一般不会被认为很危险
But given the severe limitations of the material,
但鉴于材料上有严格的限制
it was an incredible effort of ingenuity.
这份巧思还真是令人难以置信
This is the myth that was almost plausible so many times.
这条流言曾多次看似可行
It was looking so good in the beginning.
一开始形势真的太好了
We started out with our ice cannonballs.
我们从制♥作♥冰制炮弹开始
Fired out of a real cannon at high speed.
以高速发射真正的炮弹
Then we went to the breeches,
然后我们开始研制后膛
and we found a breech size that would hold
我们找到了一种可以承受
a reasonable amount of black powder.
合理分量黑火♥药♥的后膛尺寸
We put the whole thing together, built a full-size cannon,
我们将零件组装成一个真实尺寸的大炮
brought it out here to face our army.
并带来这里直面我们的敌人
And it was, again, looking very promising.
又一次看起来很有希望
But unfortunately,
但不幸的是
on the one that would've caused the most damage,
那一枚本有可能造成最大伤害的炮弹
which is the one that sailed over the army's heads
直接飞过了敌军脑袋
and hit the wall,
打在了墙上
that's the one where the cannon itself exploded.
就在那时大炮自己爆♥炸♥了
And for this myth to be plausible,
如果这个流言可行的话
we have to have damage and range and reusability all in one.
伤害射程和可重复利用三者缺一不可
And that just never happened.
可惜最终还是没有实现
So, unfortunately,
因此非常不幸
I think we have to bust this one.
我们不得不终结这个流言了
And I'm not happy about it.
我一点也不高兴
Table tennis,
乒乓球
one of the fastest ball sports on the planet.
地球上最快的球类运动之一
But surely it can never be fast enough... to be fatal.
但这个速度还不足以致命
So it all comes down to this,
现在到了最后阶段
a ping-pong ball going 1,100 miles per hour...
一枚时速1770公里的乒乓球
Go.
发射
versus flesh.
与肉体的对抗
Which one's gonna win?
谁会获胜呢
We're about to find out.
我们这就来看看
For our lethality test,
关于我们的致命性实验
today's human analogue will be played by a pork shoulder,
今天由一块猪肩肉来充当人类的替身
otherwise known as a pork butt,
也可以被叫做猪臀
because pork has four shoulders and two of them are butts.
因为猪有四个肩膀其中两个是臀部
It's true. Look it up.
真的不信你自己去查
The question is, will the world-record-breaking ball
问题是史上最高速的球是无损的从猪臀上
bounce harmlessly off the butt or penetrate with lethal force?
弹开还是以致命之力穿透猪臀
Time to turn some potential energy into some actual energy.
是时候让能量具现化了
You ready?
你准备好了吗
I'm ready. Okay.
我准备好了好的
Short barrel, 300 p.s.i., lethality test
短管 207万帕致命性实验
with a pork butt
目标猪臀
in three, two, one, go.
倒数三二一发射
That was a blast... Literally.
这可真是一阵冲击波啊真的
But how did our porcine pal fare?
但我们的猪朋友还好吗
All right, let's look at the damage.
让我们看看造成的伤害
Dude.
兄弟
There's, like, flesh trauma
这里有一个深达3.8厘米的
going down an inch and a half into here.
肉体创伤
That's impressive.
这可真不可思议
I must admit, if you had asked me beforehand,
我必须承认如果你事先问我
I would've told you that I thought the ping-pong ball
我会告诉你我认为乒乓球
was going to bounce right off of the pig.
会从猪肉上弹开
I thought the mass of the two objects was such
因为这两个物体的质量让我认为
that the ball really wouldn't do that much damage.
乒乓球真的不可能造成这么大的伤害
I am shocked by how much damage it did.
它造成这么大的伤害我真的很吃惊
Now, that thing actually penetrated.
那玩意儿真的穿过去了
That's ping-pong-ball-shaped.
这个是乒乓球形状的
That is a shocker.
真令人惊讶
That would hurt.
被打到肯定很疼
But I think we still need to call that this a non-lethal hit.
但我认为仍得认定这个为不致命的一击
It did not penetrate all the way through the flesh
它没能完全的穿透这块肉
or leave some gaping wound,
或者打出一个洞来什么的
and barring some lucky hit, that is not a deadly hit.
除非走运否则这就是不致命的
This is a substantial flesh wound, but it ain't lethal.
这个确实对肉体造成了伤害但并不致命
Yep, despite the extreme air pressure
是的尽管极高的压强
and a supersonic ball making the pig fly,
和一个超光速的球让猪肉飞出去了
the impact did not mortally harm the ham.
火腿上并无致命性的伤害
So, final verdict?
那最终裁决是
A mach 1.4 ping-pong ball
一枚马赫数为1.4的乒乓球
might just be the fastest ping-pong ball in history...
可能只不过是史上最快的乒乓球而已
Extremely dangerous, but not lethal.
非常危险却并不致命
Not lethal at all. The myth is busted.
一点也不致命流言被终结了
Busted, it is. Let's get out of here.
确实终结了我们出去吧
