Welcome back to Smarter Every Day.

歡迎回到更聰明每一天。

Have you ever been driving along

你有沒有被駕駛沿

and you suddenly stop and realize that you're moving

你突然停止，並意識到你正在移動

around this world in a bubble of glass?

圍繞這個世界玻璃的泡沫？

It's kind of weird if you think about it.

這是一種奇怪的，如果你仔細想想。

But it's really cool.

但是，這真的很酷。

Engineers have designed the glass in your car

工程師們在車內設計了玻璃

to be extremely safe, so that when you have a wreck

是非常安全的，所以，當你有一個殘骸

you decrease the chance that you're getting

你減少你得到的機會

cut in half like the bad guy in Ghost.

削減一半像壞人的鬼。

Remember the movie Ghost? Anyway.

還記得電影鬼？無論如何。

So today on Smarter Every Day

所以今天對智慧的每一天

I want to investigate the two different types of glass

我想調查兩種不同類型的玻璃

that go into car windows.

即進入車窗。

On the side you have tempered glass,

在側面你有鋼化玻璃，

kind of like a Prince Rupert's Drop, but flat.

有點像魯珀特王子港的下降，但平。

And on the windshield you have annealed glass.

而在擋風玻璃上你退火玻璃。

First let's talk about windshields.

首先讓我們來談談擋風玻璃。

Glass on a windshield is designed to take a hit from a rock and not fall in on your lap.

玻璃在擋風玻璃上的目的是要一擊的石頭，而不是你的大腿上裡鑽

However, glass on the side windows are different.

然而，玻璃上的側窗是不同的。

To demonstrate that, I got a window out of a car in a junkyard

為了證明這一點，我在一個垃圾場有一個窗口了車

and we're gonna hit it and just watch what happens.

而我們將打它，只是看會發生什麼。

Check out how it breaks.

看看它是如何打破。

It doesn't break.

它不會破壞。

That's because it's designed to be very very strong in the center

這是因為它的設計是非常非常強的中心

but not on the edge.

但不是在邊緣。

Watch what happens if we do the same thing on the edge.

看，如果我們做同樣的事的邊緣會發生什麼。

[shatters]

[碎裂]

The whole thing shatters.

整個事情打破。

To understand exactly why this happens

要確切地理解為什麼會這樣

we're gonna go to my driveway and use a high speed camera

我們要去給我的車道，並用高速攝影機

to analyze this at 20,000 frames per second.

分析這一每秒20000幀。

What are you doing Mr Helper?

你在做助手先生？

- Holding glass.

- 端著酒杯。

- He's holding the glass. This is not tempered glass.

- 他拿著酒杯。這不是鋼化玻璃。

We've got a high speed camera, this is a V1610

我們有一個高速的攝像頭，這是一個V1610

which at the time that we made this video is the fastest

這在我們做這個視頻是最快的時間

high speed camera on the market.

高速攝像機在市場上。

And I have another helper over here.

而且我還有一個幫手在這裡。

Not you.

不是你。

What are you doing?

你在做什麼？

Pushing the button when the camera breaks..

按下按鈕時，相機打破..

I mean when the, um..

我的意思是，當，嗯..

- The camera's not gonna break! [laughs]

- 相機的不是要去突破！ （笑）

- The glass.

- 玻璃。

- When the glass breaks, and what does that do?

- 當玻璃破裂，以及是什麼呢？

- Start the camera.

- 啟動相機。

- That's right. OK.

- 那就對了。好。

So what we're gonna do is we're gonna drop tempered glass

那麼，我們該怎麼辦，我們還是會下降鋼化玻璃

and not tempered glass,

和不鋼化玻璃，

and we're gonna show the difference between the two.

我們要去顯示兩者之間的區別。

And there's a special announcement at the end of this.

還有一個特別佈告本月底。

So, let's do some science.

所以，讓我們做一些科學。

You can move buddy.

您可以將好友。

- I can move?

- 我可以移動？

- I've got it. Yep, safety glasses on.

- 我懂了。是的，安全眼鏡上。

You ready little girl?

你準備好了的小女孩？

Ready?

準備？

3.. 2.. 1..

3。2。1 ..

[shatters]

[碎裂]

[laughs] OK, did you do it?

[笑] OK，你做了嗎？

[slowed shatter]

[放緩粉碎]

OK you ready buddy?

OK，你準備好哥們？

Tempered.

鍛煉。

Are you ready?

準備好了嗎？

Do your best.

做最好的自己。

3..2..1..

3..2..1 ..

Did you get it?

你明白了嗎？

It didn't break.

它沒有打破。

The tempered glass didn't break.

鋼化玻璃沒有突破。

Dropping from higher this time.

從更高的這段時間刪除。

Try to drop it on the corner too.

嘗試砸在角落裡了。

3.. 2.. 1..

3。2。1 ..

Yahaa!

Yahaa！

It's not breaking!

它不破！

OK so it wasn't breaking so we're gonna tape this wrench onto the bottom

行，所以它沒有打破，所以我們要去的錄像帶扳手在底

of the glass.

玻璃的。

And the idea is that maybe the wrench will actually twist the edge

而這個想法是，也許扳手實際上會扭曲邊緣

and break the glass when it impacts.

並打破玻璃時，它的影響。

We'll see.

我們拭目以待。

Hopefully it works.

希望它的工作原理。

3.. 2.. 1..

3。2。1 ..

[smashes]

[摔破]

There we go.

在那裡，我們走了。

[slowed smash]

[放緩粉碎]

OK this is the aftermath.

好了，這就是後果。

You can see on the left we have tempered glass.

您可以在左邊，我們鋼化玻璃看到。

On the right, that's just normal annealed glass

在右邊，這只是普通退火玻璃

so the question is, why do they break differently?

所以現在的問題是，為什麼他們打破不同？

It's pretty awesome though isn't it.

這是相當真棒，雖然是吧。

OK so what did we learn from this experiment?

行，所以我們也從這個實驗學到什麼？

Annealed glass is just normal glass that's been

退火玻璃是只是正常的玻璃一直

heated up in the manufacturing process and then allowed to cool down gradually.

加熱在製造過程中，然後使之冷卻逐漸。

This cooling relieves any internal stresses on the glass.

該冷卻減輕在玻璃任何內應力。

You'll notice when the annealed glass breaks,

你會注意到在退火玻璃破裂的時候，

not only is the cracking slow but sometimes it doesn't even make it to the other side of the glass.

不僅是裂化慢但有時甚至不使其向玻璃的另一側。

Which is good for windshields.

這是良好的擋風玻璃。

A small crack in one spot of the windshield doesn't completely blind your vision.

一個小裂縫在擋風玻璃上的一個點並不能完全蒙蔽了你的視野。

Also they put a piece of plastic between two sheets of annealed glass

此外，他們把一塊塑料兩片退火玻璃之間

so that these big shards don't fall in and cut you inside the car.

因此，這些大碎片不屬於和砍你的車內。

Tempered glass is very different.

鋼化玻璃是非常不同的。

Instead of allowing the glass to cool down slowly

而不是讓玻璃降溫緩慢

they use forced air to cool down the outer sides of the glass really quickly

他們用強風真的很快降溫玻璃的外側

which leaves the inside of the glass hot.

這讓玻璃熱的內部。

Kind of like how a Prince Rupert's Drop is made if you remember that video.

有點像如何魯珀特王子港的落差，如果你還記得的視頻製作。

The inside is still hot so as it cools down

內部仍是熱點，從而冷卻下來

it shrinks and pulls in which puts the outside of the glass in compression

它收縮並拉起，其中在壓縮使玻璃的外

but the inside in really high tension.

但在真正的高張力內。

Just like the Prince Rupert's Drop if you can get through that hard outer layer

就像魯珀特之淚如果可以通過硬外層得到

it releases the tension and the feathering front destroys the entire sheet of glass.

它釋放的張力和羽化前破壞玻璃的整個工作表。

On the Prince Rupert's Drop you have to get through the outside curved surface

在魯珀特之淚，你必須打通外曲面

of the drop to release the tension.

滴的釋放張力。

But on a car window you have to get through the flat tempered surface to release the tension.

但在車窗外，你必須通過平鋼表面得到釋放緊張的情緒。

With a sheet of glass though, we have to start it along one of the edges.

與玻璃板雖然，我們必須開始它沿著所述邊緣之一。

Even after you break tempered glass

即使你打破鋼化玻璃

you can sometimes still hear the stress releasing itself as it continues to break.

有時你可以仍然聽到應力釋放自己，因為它不斷突破。

So there you go.

所以你去。

The next time you need to escape from a car window

下一次你需要從車窗逃生

remember that the windshield is annealed

記住，擋風玻璃退火

and it's gonna hold together

並且它會抱在一起

but the side windows are tempered and they're gonna bust out

而側窗的鍛煉，他們打爆了

completely as long as you hit them on the edge.

完整，只要你打他們的優勢。

OK I'm just gonna go for this.

好的，我只是要去這一點。
