Not only does it allow us to breathe,

它不僅能讓我們呼吸。

which I think we can all agree is a good thing,

我想我們都同意這是一件好事。

but if you compress it and contain it,

但如果你把它壓縮幷包含。

you can have loads of fun.

你可以有很多樂趣。

Like defying the laws of physics.

就像藐視物理定律一樣。

Or for wacky furniture.

或為古怪的傢俱。

Whack!

捶！

See?

看到了嗎？

The secret to understanding and using compressed

瞭解和使用壓縮的祕密

air is to realize that all it wants to do

空氣是意識到它想做的一切。

is stop being compressed air.

是停止被壓縮空氣。

It wants to escape and in so doing air

它想逃跑，這樣做空氣

teaches us valuable science on pressure differentials

教給我們寶貴的壓差科學知識

and conservation of energy.

和能量的保存。

If air in one part of a container is compressed,

如果容器中的某一部分空氣被壓縮。

it will apply pressure to all other parts

它將對所有其他部分施加壓力

until all areas are the same pressure.

直到所有區域的壓力相同。

This is due to conservation of energy.

這是由於能量的守恆。

When a container of compressed air is open to the atmosphere,

當壓縮空氣的容器向大氣開放時。

the high pressure inside equalizes

內壓平衡

with a lower pressure outside, producing

外部壓力較低，產生

a force as the air escapes.

當空氣逸出時，一種力量。

And whatever is containing the compressed air needs to have

而不管是裝壓縮空氣的東西，都需要有足夠的空氣。

the material strength to withstand

材料的承受力

the pressure differential, otherwise, it will fail.

壓差，否則會失效。

To sum up, pressure changes will be transferred

綜上所述，壓力的變化將被傳遞到

to all parts of the container.

到容器的所有部分。

Give something at high pressure an opening,

給高壓的東西一個開口。

and it will take it and escape with force.

它就會拿著它，強行逃跑。

And finally, whatever you do, make sure the container

最後，無論你做什麼，都要確保容器的安全性

you're using is strong enough.

你使用的是足夠強大的。

So now you know.

所以現在你知道了。

But do our researchers know?

但我們的研究人員知道嗎？

Yes, they do.

是的，他們做。

The jumper has cleverly demonstrated

跳樓者巧妙地展示了

a basic pneumatic system.

一個基本的氣動系統。

He adds kinetic energy, with his jump, which causes

他增加了動能，與他的跳躍，這導致了。

a pressure change in the bag.

袋子裡的壓力變化。

And due to conservation of energy,

而由於能量的守恆。

the kinetic energy is transferred to her,

的動能傳遞給她。

and she then transfers that same energy to the bedside table

然後她把同樣的能量轉移到床頭櫃上。

via her head.

通過她的頭。

How about something a little more high tech?

不如來點更高科技的東西？

Surely these amateur rocket engineers

當然，這些業餘的火箭工程師

understand pneumatics.

瞭解氣動。

Turns out, they don't.

事實證明，他們沒有。

The young researcher was trying to compress

年輕的研究人員正試圖壓縮

air by jumping on the pump.

通過跳到泵上的空氣。

Unfortunately, he misses.

可惜，他失手了。

But Oliver does it.

但奧利弗做到了。

When the pump is pressed, the pressure differential created

當泵被按下時，所產生的壓差

applies a force that launches the rocket.

施加一個發射火箭的力。

Good to get a closer look at the physics.

很好，可以近距離觀察物理學。

Understanding the science allows you to take

瞭解了科學，您就可以採取

advantage of the science.

科學的優勢。

Like building a beach trampoline.

就像建一個沙灘蹦床。

Fun times.

好玩的時候。

Yeah, less fun times.

是啊，少了點樂趣的時光。

The membrane of the beach ball didn't have the material

沙灘球的膜沒有材料。

strength to contain the higher pressure produced by our more

強度，以控制我們的更高壓力。

sure footed researcher.

穩健的研究者。
