It's a fundamental building block of life.

It makes up 78% of the atmosphere, AND it's in these tiny micro bubbles,

它佔大氣層的 78%，而且存在於這些微小的氣泡中、

在我的星巴克 "硝基冷啤酒 "中。

And yes, this episode is sponsored by Starbucks.

沒錯，本期節目由星巴克贊助。

They challenged me to liquify nitrogen out of the air,

他們挑戰我從空氣中液化氮氣、

and that's what I'm gonna be doing in this video.

But first I'm gonna try Nitro Cold Brew for the first time...

但首先，我要第一次嘗試硝化冷啤酒

It's subtly sweet without having to add sugar,

and I'm gonna explain why nitrogen makes this possible.

我將解釋為什麼氮氣能讓這一切成為可能。

But first I'm gonna try to liquify some nitrogen for myself out of this atmosphere.

但首先，我要試著從大氣中為自己液化一些氮氣。

we need a way to make the air really cold.

我們需要一種讓空氣變冷的方法。

And to do that, I'm going to use this cryo-cooler.

為此，我要使用這個低溫冷卻器。

So essentially what's inside here is a cylinder of helium and a couple pistons.

是以，這裡裝的主要是一個氦氣筒和幾個活塞。

There's a piston that compresses the helium down into this section,

有一個活塞將氦氣壓縮到這個部分、

and when it does that, it makes that gas really hot.

當它這樣做時，就會使氣體變得非常熱。

And so, that heat gets ejected to the surroundings through this heat sink.

是以，這些熱量會通過散熱器噴射到周圍環境中。

Then the helium is expanded down in here, and as that happens, it gets really cold.

然後，氦氣在這裡向下膨脹，隨著膨脹，它就會變得非常冷。

So it absorbs the heat from the surroundings.

So this is the part of the cryo-cooler that is going to get down to less than -200°C.

是以，這是低溫冷卻器的一部分，其溫度將降至零下 200 攝氏度以下。

This is the place where we can really liquify some gas.

在這裡，我們可以真正液化一些天然氣。

and first do a sort of simple proof-of-concept and make sure that this is working

首先做一個簡單的概念驗證，確保它能正常工作

so uuh, I brought him here to help me make this happen.

所以，我帶他來幫我實現這個願望。

How should people know you, Allen? Like what do you get into, what's your thing?

人們應該如何認識你，艾倫？比如你喜歡什麼，你的愛好是什麼？

艾倫：我是一個失敗的 "神話剋星"、

and also I have a YouTube channel called "Sufficiently Advanced".

此外，我還有一個名為 "Sufficiently Advanced "的 YouTube 頻道。

Derek VO: You may know Allen from his creations and,

德里克-沃：你可能從艾倫的創作中認識他、

relevant to this project, shooting liquid nitrogen from his hands.

Allen: I'm definitely breaking your drill by the way >D: I see that :) I see that.

艾倫：順便說一句，我絕對是在破壞你的演習 >D: 我明白了:)我明白了

Derek: So now, let's turn it on, and you can listen, you can hear it turn on.

德里克：現在，讓我們打開它，你可以聽，你可以聽到它打開的聲音。

been running the cryo-cooler for about 4 hours.

低溫冷卻器已經運行了大約 4 個小時。

Hopefully getting some liquid air in there.

Allen: I bet you 50 bucks there's at least 50 millilitres of liquid air in there.

艾倫：我跟你賭 50 塊錢，裡面至少有 50 毫升液態空氣。

Derek: It ISN'T even that much,>< but I will be amazed if it happens. > Allen: It's like a whole-

德里克：根本沒有那麼多，但如果真的發生了，我會很驚訝。

Allen: Oh, that- that's 50 millilitres, right there. Derek: I bring you a 50 millilitre beaker.

艾倫哦，那是 50 毫升，就在那兒。德里克：我給你拿一個 50 毫升的燒杯。

Allen: I hear something..! >I hear something!< Derek: Oh ohoh >< oh oh!

艾倫：我聽到了什麼......我聽到了什麼！&lt; 德里克：哦哦&gt;&lt;哦哦！

Allen: That sounds like... Derek: How much have we made?

艾倫：聽起來好像......德里克：我們賺了多少？

Allen: 50 millilitres.. Derek: Is that how much we've made? Allen: ..of liquid air!

艾倫：50 毫升。這就是我們製造的量嗎？艾倫： ......液態空氣！

Derek: OooohH..! Cameraman: Oh hoho hoh! Allen: 50! 50!

Derek: OooohH..！攝影師：Oh hoho hoh！50！50!

答：老兄，那是 50 毫升液態空氣。

Derek VO: I know it doesn't look like much, but to make 50 ml of liquid air,

Derek VO：我知道看起來不多，但要製作 50 毫升液態空氣、

we needed to condense around 35 litres of air from the room.

我們需要從房間裡冷凝大約 35 升的空氣。

Derek: What's funny to me is I've done a lot of experiments with liquid nitrogen,

德里克：讓我覺得有趣的是，我用液氮做過很多實驗、

but this feels like the most precious... [Allen laughs] liquified gas that I've ever had

但這感覺就像最珍貴的......[艾倫笑] 我曾經擁有過的液化氣

Allen: I know we didn't shake on it, but you definitely owe me $50.

艾倫：我知道我們沒有握手，但你肯定欠我 50 美元。

[Allen erupts with laughter]  [Cameraman chuckles]

[艾倫爆發出笑聲] [攝影師笑聲]

Derek: 'Cause that's impressive from just a few hours!

德里克："短短几個小時就這麼厲害！

Derek VO: Liquid oxygen is paramagnetic, which means it's attracted to permanent magnets.

德里克-沃：液氧具有順磁性，這意味著它能被永久磁鐵吸引。

I'm going to use this effect to try to extract some liquid oxygen.

我要利用這種效果，嘗試提取一些液態氧。

Derek: Something came out. Allen: Hey, dude, you got it!

有東西出來了艾倫：嘿，夥計，你猜對了！

You got some. Derek VO: See that droplet at the end of the magnets?

有了看到磁鐵末端的液滴了嗎？

To make sure it really was liquid oxygen, we tested how it affected a flame.

為了確保它真的是液氧，我們測試了它對火焰的影響。

Allen: So that's 'for-sure' oxygen, that is liquid oxygen.

艾倫：那就是 "確定 "的氧氣，也就是液態氧。

Derek: You can see how the matchstick REIGNITES with the liquid oxygen,

德里克：你可以看到火柴棒是如何與液氧結合的、

and the flame spreads towards the higher concentration of oxygen.

火焰向氧氣濃度較高的地方蔓延。

[Low-pitched squeaking and chuting sounds emanate from the flame]

[火焰發出低沉的吱吱聲和嘁嘁聲]

[quiet Alien Chestbuster squawk/click sounds emanate from the experiment]

[安靜的外星胸霸叫聲/點擊聲從實驗中傳出]

Derek: There you go, we have made: liquid air.

德里克：就是這樣，我們製造出了：液態空氣。

Next step: remove the oxygen, and just make liquid nitrogen.

下一步：去掉氧氣，直接製造液氮。
