It's made of Lucia, Ah, purple clay and it's called pp boy, because when you pour hot water over its hit, it starts to pee.

它是用露西亞做的，啊，紫色的粘土，它叫pp男孩，因為當你把熱水澆在它的命門上，它就會開始撒尿。

Oh, the PP boy is what's called a T pet.

哦，PP仔就是所謂的T寵。

The touch on is a talent champion thing today.

摸上是當今的人才冠軍的事情。

Uh, whether hauling thing Bandiera Huang is a t pet artist.

呃，是否牽引事情班迪拉黃是一個t寵物藝術家。

Her hometown eating is famous for its teapots made from a local cle called Sha gonna happen Me Oh, so you're worshiping in t gonna make a dumb.

她的家鄉吃的是著名的茶壺，由當地的一種叫沙會發生我哦，所以你在崇拜在t會做一個啞巴。

In fact, I'm going to the show on a patio Had one hell of a show.

事實上，我要去天井裡看演出，看了一場精彩的演出。

Even socio The, uh Yuh has it in my feet and there are many types of tea pets which your video may Catriona would have, uh, she go Ponsi Hannah equals e o me, Tom Bada.

即使是社會的，呃Yuh有它在我的腳，有許多類型的茶葉寵物，你的視頻可能凱特麗娜會有，呃，她去Ponsi漢娜等於E O我，湯姆巴達。

But the most popular T pet of all is the PP boy.

但最受歡迎的T寵是PP仔。

Shang Kwan Sanya Shahana.

上關三亞沙哈那。

Touch on your Syrian shoes equals touch.

摸在敘利亞鞋上等於摸。

You negotiate a magic uh, joining that Ballymena Johanna Susannah Sanyoto Because of the way it reacts to hot water, some researchers believe the pp boy could be the first thermometer known to mankind.

你談判一個神奇的呃，加入那個Ballymena Johanna Susannah Sanyoto由於它對熱水的反應方式，一些研究人員認為pp男孩可能是人類已知的第一個溫度計。

So I wanted to know what is the science behind it?

所以我想知道它背後的科學原理是什麼？

E called up my friend Alex on.

E打電話給我的朋友Alex上。

We tried to make our own PP boy, using glass beakers and flasks to see how that hot water reaction works.

我們嘗試著用玻璃燒杯和燒瓶自制PP仔，看看那個熱水反應是如何進行的。

This is gonna be the PP boy.

這將是PP男孩。

A big head, Okay, on a very a small hole in comparison to the head.

一個大頭，好吧，在一個非常小的孔相比，頭。

That's important thing.

這是很重要的事情。

Alex is going to use this flask to show how thermodynamics drives what's happening inside a PP boy.

亞歷克斯要用這個燒瓶來展示熱力學是如何驅動PP男孩體內發生的。

What we're going to dio is we're going to run exactly the same procedure that we run on a PP boy.

我們要做的是，我們要運行完全相同的程序，我們運行在一個PP男孩。

Now just say you you can see the water level a bit better than we're gonna add some of this lovely pink food color into it.

現在就說你... ...你可以看到水位更好一點... ...我們要在裡面加一些這種可愛的粉紅色的食用色素。

The first step we need to do, we need to get the air inside this very, very hot so that it expands way cool it down the air inside will begin to contract.

第一步我們需要做的，我們需要讓這個裡面的空氣非常非常的熱，讓它膨脹的方式冷卻下來，裡面的空氣會開始收縮。

As it shrinks, the pressure will get lower, but the air pressure outside stays the same.

隨著它的收縮，壓力會越來越低，但外面的氣壓保持不變。

So what's gonna happen is actually the air outside the above US will actually push the water inside you can see the water is being pushed up.

所以要發生的事情其實是美國上面外面的空氣其實會把裡面的水推上去，你可以看到水被推上去了。

Now, the next step is how you get the water out.

現在，下一步就是如何把水弄出來。

So what we're gonna do is we're gonna pour some boiling water back onto the head of the P people.

所以，我們要做的是，我們要倒一些開水回到P人的頭上。

This'll cause the gas inside that is now shrunk to expand again.

這樣就會使現在收縮的裡面的氣體再次膨脹。

And it's gonna push out all of that water on.

它要把所有的水推到。

It's gonna appear something like a PP boy.

會出現類似PP男孩的東西。

Probably because the whole isn't quite a small Comparatively, we're not gonna get a big jet.

可能是因為整個不是挺小的 比較而言，我們不會弄個大飛機。

You should see a similar result.

你應該會看到類似的結果。

Let's give us a good way.

讓我們給我們一個好辦法。

Got how it goes.

得到了如何去。

Keep going.

繼續走吧

Yeah.

是啊。

Now you can see it's peering out.

現在你可以看到它的窺視。

Yeah, so interesting.

是啊，太有趣了。

The science behind this, the expansion on, then contraction and then expansion Contraction off air is essentially the same physics behind a steam engine.

這背後的科學原理，先膨脹上，再收縮，然後再膨脹收縮掉空氣，本質上和蒸汽機背後的物理原理是一樣的。

It's the expansion that pushes the piston out.

是膨脹把活塞推出來的。

And it's a contraction that pulls a pistol in, just like we're pulling water in on pushing it back out.

而這是一種收縮，把手槍拉進去，就像我們把水拉進去在把它推回去一樣。

That's exactly how it steam engine would work.

這正是它蒸汽機的工作原理。

Just like exactly So that makes you think this could be used like involvement as a very crude thermometer.

就像正是這樣，讓你覺得這可以像參與一樣，作為一個非常粗糙的溫度計。

Let's give it a try.

讓我們試試吧。

Let's see the water's hot.

讓我們看看水的熱度。

There he goes.

他走了。

Definitely hot enough.

絕對夠辣。

Could it be used as an accurate the moment?

能否作為準確的當下？

Er, not without a lot of extra physics and a lot of extra mathematics.

呃，沒有很多額外的物理學和很多額外的數學是不行的。

So it's just a fun thing.

所以這只是一件有趣的事情。

Yeah, I think the novelty value.

是啊，我覺得新奇的價值。

Well, cool.

嗯，很酷。

Cheers.

乾杯。

So there you go.

所以，你去那裡。

Is the P B boy the oldest thermometer in the world?

P B男孩是世界上最古老的溫度計嗎？

Probably not, but it sure adds a lot of fun to tee time the oh.

也許不是，但它確實給開球時間增加了很多樂趣哦。
