Hey what's up guys, 語氣意圖

嘿，大家好，

we're back today with another dry ice experiment. 文化背景

我们今天又带来了一个干冰实验。

You've seen people throwing this stuff in their swimming pool

你们可能见过有人把这东西扔进游泳池里，

where it makes a really cool effect.

会产生非常酷的效果。

And you might remember last summer I went to the hot springs

你们或许还记得去年夏天我去了温泉，

and dumped in 100 lb of this stuff

往里面倒了100磅这玩意儿，

to see how it would react with hot water. 短語搭配

看看它和热水会产生什么反应。

But today the ground is frozen over. 短語動詞

但是今天，地面都结冰了。

My fish pond has a thin layer of ice,

我的鱼池上也结了一层薄冰，

so I wanted to see what would happen 語法

所以我想看看，

if we tried throwing dry ice into a frozen fish pond.

如果我们把干冰扔进结冰的鱼池里会发生什么。

Let's check it out. 短語動詞

我们来看看吧。

But

不过，

Wait, there's more. 表達脈絡

等等，还没完。

We're going to throw this bucket of dry ice into our fish pond.

我们要把这一整桶干冰都扔进鱼池里。

And don't worry, 語氣意圖

别担心，

there aren't any fish in there.

里面没有鱼。

Now this just froze over last night,

这昨晚才刚结冰，

so the layer of ice isn't that thick. 語法

所以冰层还不是那么厚。

That means if we throw the dry ice hard enough,

这意味着如果我们用力把干冰扔下去，

we might be able to get it to penetrate straight through 語法

它可能会直接穿透冰层

down into the water.

掉进水里。

Is the dry ice going to crack through

干冰是会砸穿冰层，

or is it just going to skitter around on the top? 用詞

还是只会在冰面上滑来滑去？

This will be interesting to see.

这将会很有趣。

Let's see what happens

让我们看看

if we just throw one chunk of dry ice in there.

如果仅仅扔进去一块干冰会发生什么。

That's awesome.

to get it through.

还需要费点力气。

And look how

而且你看，

Wow, look at what it's doing to the underneath the ice here.

哇，看它对这片冰层下面造成了什么影响。

It's actually forming carbon dioxide gas

它其实是在冰层下面

right underneath the ice.

形成了二氧化碳气体。

That was unexpected.

出乎意料啊。

But I guess it makes sense. 語氣意圖

不过想想也合理。

I'm going to throw another piece down right beside it

我要在它旁边再扔一块，

and see if we can get the same effect. 短語搭配

Here goes another one right over here. 短語搭配

这边再来一块。

See once the dry ice is under there, 語法

看，干冰一到了下面，

it releases carbon dioxide,

就会释放二氧化碳，

but the carbon dioxide gets trapped under the layer of ice 語法

但二氧化碳被困在冰层下面，

and exposes it.

显露了出来。

Oh man,

天哪，

that's cool.

太酷了。

Look closely at what happens here.

仔细看这里发生了什么。

There's an air bubble

有一个气泡，

and then the carbon dioxide infuses into it

然后二氧化碳注入其中，

and then it rushes out

接着迅速涌出，

and disappears.

消失不见。

What a sweet effect. 語法

多么美妙的景象。

What's cool about that gas is it's still got that misty, 語法

that is cool.
