將可樂與丙烷混合，結果絕對超乎想像！| 丙烷和可樂實驗：英語精讀講義

Hey, what's up guys?

嘿，大家好嗎？

It's a new day and a new experiment.

新的一天，新的實驗。

Now, in a previous video,

在之前的影片中，

you remember we took liquid nitrogen and put them in water bottles

你們記得我們把液態氮裝進了水瓶裡，

and made improvised nitrogen rockets.

製作了簡易的液態氮火箭。

Apparently, some people figured out you can do the same thing

顯然，有些人發現你也可以用相同的方法，

using Coke and propane.

使用可樂和丙烷來做。

So, that's what we're doing today.

所以，這就是我們今天要做的事。

Now, in yesterday's video,

在昨天的影片裡，

I showed you how we could modify the nozzle of one of these propane tanks

我向大家展示了我們如何改裝這些丙烷罐的噴嘴，

and extract liquid propane.

並提取液態丙烷。

And we went down to the store and picked up 12 500 ml Coke bottles 片語動詞

我們去商店買了12瓶500毫升的可樂，

so we could mix them together and watch the reaction.

這樣我們就可以把它們混合起來觀察反應。

Now, the funny thing about this experiment is you don't actually have to use Coke. 表達脈絡

有趣的是，這個實驗其實不需要非用可樂不可。

I'm just throwing it in because videos with Coke seem to get more views. 片語動詞

我只是把它加進來，因為帶有可樂的影片似乎觀看次數比較多。

Let me explain the process of what's about to happen. 文法

讓我解釋一下接下來要發生的過程。

We're going to open the valve on this propane cylinder,

我們將打開這個丙烷鋼瓶的閥門，

turn it upside down in a glass and collect liquid propane.

把它倒置在一個杯子裡，收集液態丙烷。

Then we're going to take the cap off our Coke bottle

然後我們要取下可樂瓶蓋，

and pour out a bit of the liquid until it's just under the line of the label itself.

倒出一點液體，直到液面剛好在標籤線下方。

From there,

從那一步起，

it's just a matter of pouring in a bit of liquid propane, 片語搭配

只需倒進一點液態丙烷，

so it sits on top and turning the bottle upside down.

讓它浮在表面，然後把瓶子倒轉過來。

Are you ready?

準備好了嗎？

Moment of truth. 慣用語

見證奇蹟的時刻。

Whoops.

哎呀。

Fail.

失敗。

Look at that.

看看這個。

What the heck?

搞什麼鬼？

That didn't work at all.

根本沒用。

Maybe we need more propane.

也許我們需要更多的丙烷。

Look at the top of the Coke there.

看看可樂的頂部。

When the propane hits it,

當丙烷接觸到它時，

it freezes and starts gumming up. 片語動詞

它結冰並開始變得黏稠。

It smells terrible.

氣味太難聞了。

It seems to form a layer of ice here,

這裡好像形成了一層冰，

so I have no idea if this is going to work.

所以我完全不知道這能不能行得通。

The idea is we just turn it over.

我們的想法是直接把它倒過來。

And look,

看，

it just spills out of everywhere.

它到處噴灑。

Look at that.

看看這個。

It's just all icy

全都是冰，

and then nothing happened at all.

然後什麼也沒發生。

Fail.

失敗。

What the heck?

搞什麼鬼？

Ow.

哎喲。

It's freezing my fingers.

我的手指快凍僵了。

Ooh, frosted.

喔，結霜了。

Okay, let's see if we can make this work.

好吧，讓我們看看能不能成功。

Ready?

準備？

Nothing.

什麼也沒有。

I'm starting to lose confidence that this actually works. 片語搭配

我開始對這東西是否真的有用失去信心了。

And those videos I saw,

我看到的那些影片，

I don't think they were using propane,

我覺得他們用的可能不是丙烷，

but they could have been using butane. 文法

他們用的可能是丁烷。

Huh.

哈。

Let's try one more time just to be sure.

我們再試一次以求確定。

If this doesn't work, 文法

如果這都不行，

I don't know what will.

我不知道還有什麼能行了。

Ooh.

喔。

There we go. 語氣意圖

來吧。

Oh boy.

喔，天哪。

Look at that.

看看這個。

Put the fire out with the Coke.

用可樂把火撲滅了。

I went through five bottles of propane 片語動詞

我用完了五瓶丙烷

and a number of various experiments

以及一系列各種不同的實驗，

and we didn't get any of them to work.

但我們一個都沒成功。

So, it kind of makes me wonder in the videos I saw, 語氣意圖

所以這讓我有點懷疑在我看過的影片裡，

maybe these guys were using butane

也許這些人用的是丁烷

instead of propane.

而不是丙烷。

Maybe that makes a difference.

也許這就是差別所在。

I'm not sure.

我不確定。

But based on my experiments today,

但根據我今天的實驗來看，

I don't think mixing propane and Coke has any kind of reaction at all. 文法

我認為把丙烷和可樂混合在一起根本不會產生任何反應。

The Coke just freezes.

可樂就是結冰了而已。

That's really about it.

真的就只是這樣。

Ooh.

喔。

Now, I don't want to let you go home empty-handed. 慣用語

現在，我不想讓你們空手而歸。

So, for one final experiment,

所以，作為最後一個實驗，

we're going to try filling up this Coke bottle 片語動詞

我們要試著把液態丙烷

with liquid propane and screwing the cap on tight.

裝滿這個可樂瓶，然後把瓶蓋轉緊。

The question is,

問題是，

is this thing going to pressurize and explode,

這東西會加壓爆炸嗎，

or will a Coke bottle actually be able to contain liquid propane indefinitely?

還是可樂瓶實際上能夠無限期地承受液態丙烷？

Okay, I got to put that down. 文法

好吧，我得把它放下。

My fingers are freezing.

我的手指快凍僵了。

Look at that.

看看這個。

Yeah, liquid propane can still give you frostbite, guys.

大家，液態丙烷依然能讓你凍傷的。

So frosty.

都是霜。

So, here we are, guys.

好了，我們到了這一步。

We got this bottle half full of propane.

我們裝了半瓶丙烷。

You can see it rises above the label there.

你們可以看到液面高出了那邊的標籤。

And the thing that I noticed right off the bat 慣用語

我立刻注意到的一件事就是

is how light the propane feels.

丙烷感覺很輕。

I mean, this bottle is halfway full

我是說，這個瓶子已經裝了一半，

and it feels like there's barely anything in it at all. 文法

但感覺裡面好像幾乎什麼都沒有。

That's super surprising to me.

這讓我超級驚訝。

So, let's go ahead and cap this thing off,

所以，讓我們把這東西蓋上，

put it in a safe place

放到一個安全的地方，

and see whether or not this thing will explode. 文法

看看它到底會不會爆炸。

So, quick update.

快速更新一下情況。

I just put the cap on the bottle

我剛把蓋子蓋到瓶子上，

and I can still squish it,

我還是能捏得動它，

which means it's not super pressurized.

這意味著它並沒有受到超大壓力。

And when I shake it,

當我搖晃它時，

it's almost like it contracts even more, 文法

它幾乎像是在進一步收縮，

like it squishes in even more.

像是往裡陷得更深了。

Now, I imagine over time this will warm up

我想隨著時間的推移，它會變暖

and it will pressurize.

並且會增加壓力。

In fact, we could probably take a blowtorch to it

事實上，我們或許可以用噴燈燒一下

and warm it up a little bit quicker.

讓它熱得快一點。

And when this thing gets to the point where I can't push my thumb into it, 文法

當這東西達到我用拇指按不動的程度時，

I'm just going to set it down

我就把它放下來，

and leave it

隨它去，

and we'll see uh see what happens.

我們來看看呃看看會發生什麼。

I'm just going to leave this right here.

我就把它放在這裡。

So, check this out, guys. 語氣意圖

你們來看看這個。

It's been about 20 minutes.

已經過了大約20分鐘。

We've had this thing sitting out long enough 文法

我們把這東西放在外面足夠長的時間了，

that the propane has warmed up

丙烷已經升溫

to outside temperature here,

到了這裡的室外溫度，

which today is about 45 degrees Fahrenheit.

今天大概是華氏45度。

The bottle is pressurized,

瓶子已經加壓了，

but it hasn't warped

但它沒有變形，

and it's still to the point where I can push my thumb in

而且目前我還能用大拇指按進去

and move the plastic a little bit.

稍微讓塑膠移動一下。

So, I don't think this is going to explode.

所以我認為這不會爆炸。

It seems that theoretically, 語氣意圖

看來從理論上講，

we can store liquid propane in a Coke bottle.

我們可以把液態丙烷儲存在可樂瓶裡。

Probably not the safest idea, 語氣意圖

也許不是最安全的想法，

but it looks like you actually can do it.

但看起來實際上你真的能做到。

Okay, durability test.

好了，耐用度測試。

And it stays intact.

它保持完好無損。

That looks pretty cool.

看起來很酷。

So, see guys,

所以，看到了吧各位，

looks like it's a viable idea.

看起來這是個可行的主意。

A Coke bottle will hold liquid propane.

可樂瓶可以裝液態丙烷。

We've dropped this thing,

我們摔過這東西，

we've warmed it up,

我們加熱過它，

and uh I think now it's time to kill it off. 片語動詞

而且，我想現在是時候把它解決掉了。

Let's see what happens when I take the cap off.

讓我們看看拔下蓋子會發生什麼。

Look, it starts bubbling.

看，它開始冒泡了。

Woah.

哇。

That's crazy.

太瘋狂了。

And it started cooling down again as well.

它又開始降溫了。

Did you notice that?

你們注意到了嗎？

All right,

好吧，

let's light it off and dump it out.

我們把它點燃倒出來吧。

Ooh.

喔。

Toasty.

暖烘烘的。

Check it out.

看看這個。

Nice big ball of fire.

好大一個火球。

That's very satisfying.

非常過癮。

Very satisfying,

非常過癮，

very cool.

非常酷。

And look,

看，

it warped my Coke bottle.

它把我的可樂瓶弄變形了。

So, guys,

那麼，各位，

I just turned off our propane bottle

我剛關掉了我們的丙烷瓶

so we can summarize here for a minute what we've just learned. 表達脈絡

這樣我們可以花一分鐘總結一下我們剛才學到了什麼。

We started off with the purpose to see if mixing propane and Coke together

我們一開始的目的是看看把丙烷和可樂混合在一起

would make an improvised bottle rocket.

是否能做一個簡易的瓶子火箭。

But what we found actually happens is 表達脈絡

但我們發現實際發生的是，

the propane freezes the Coke,

丙烷把可樂凍住了，

preventing any significant reaction from taking place. 文法

阻止了任何明顯反應的發生。

We tried a number of variations of experiments to see if we could get it to work, 文法

我們嘗試了許多不同變數的實驗想看看能否成功，

but all of those attempts failed.

但所有嘗試都失敗了。

Oh boy.

喔天哪。

Next,

接下來，

we tried filling up one of the empty Coke bottles themselves

我們嘗試在一個空可樂瓶中

with liquid propane and screwing the cap on tight

裝滿液態丙烷並轉緊瓶蓋，

to see if we could get it to explode.

看看我們能否讓它爆炸。

But rather than exploding, 文法

但它不僅沒有爆炸，

it actually warmed up to the outside air temperature

反而升溫到了外部空氣溫度，

and became a crystal clear liquid. 片語搭配

變成了一種晶瑩剔透的液體。

Very beautiful and apparently very stable as well.

非常漂亮，顯然也非常穩定。

We tried drop testing the bottle for durability 用詞

我們嘗試了跌落測試來檢驗瓶子的耐用度，

and found that it stayed intact. 片語搭配

發現它完好無損。

So, we unscrewed the cap,

所以，我們轉開蓋子，

lit off the gas,

點燃氣體，

and poured it on the concrete.

然後把它倒在水泥地上。

Well, that's it for this set of experiments, guys.

好了，這系列實驗到此結束，各位。

Thanks for joining me,

感謝你們的觀看，

and I'll be looking for you in the next video.

我會在下一個影片裡等你們。

Talk to you then.

到時候見。

Wouldn't that be great if it just exploded 語氣意圖

如果它現在直接在我手裡爆炸，

in my hand right now?

那豈不是很棒？

Oh shoot.

喔，糟糕。
