玻璃真空室會內爆嗎？：英語精讀講義

What's up guys?

大家好？

We are back in the lab again today with our homemade vacuum chamber.

今天我們又回到實驗室，帶著我們自製的真空室。

You remember we built this in a previous project and the whole purpose of this thing is to degas silicone 文法

你們記得在之前的專案中我們做過這個，它的主要用途是幫矽膠除氣，

so we don't have air bubbles trapped in our silicone molds.

這樣我們的矽膠模具裡就不會有氣泡殘留了。

The only issue I have with it is that it's made out of a pressure pot 文法

我對它唯一不滿的是它是用壓力鍋做的，

and this thing is not see-through. 用詞

而且這東西不透明。

So if we're doing some cool experiments,

所以如果我們做一些很酷的實驗，

we won't be able to see them.

我們就看不見裡面的情況。

So I went down to the Super Center and picked up some of these glass cookie jars 片語動詞

所以我去了一趟超級中心，買了一些這種玻璃餅乾罐，

and wondered if they could work as an option as well.

想知道它們是否也能作為一個備選方案。

Now this project was inspired by my cousin Ty Moser with the Monoloco Workshop who used one of these glass jars to build a vacuum chamber on his channel

這個專案是受到了我表哥 Ty Moser 在 Monoloco Workshop 頻道的啟發，他用這種玻璃罐在頻道裡做了一個真空室，

and I'll put a link in the description to where you can see that.

我會在描述裡放個連結，大家可以去看看。

Now the last thing we want with a vacuum chamber is for it to implode on us 講解

對於真空室來說，我們最不希望看到的就是它發生內爆，

right as we're doing some work. 片語搭配

尤其是正在幹活的時候。

That will spread glass all over the room

那會把玻璃碎片弄得滿屋子都是，

possibly into your face and we don't want that to happen.

甚至可能噴到臉上，我們可不想發生這種事。

So before we actually use these in the real world,

所以在實際投入使用之前，

we need to test them and make sure they're capable of holding up to the vacuum pressure. 片語動詞

我們需要測試一下，確保它們能承受得住真空壓力。

Now you probably remember that with our pressure pot,

你們可能還記得，在之前的壓力鍋上，

I made a Proto Putty seal that can be removed and replaced.

我用 Proto Putty 做了一個可以拆卸更換的密封圈。

I also did the same thing with these glass jars as well.

我在這個玻璃罐上也做了同樣的處理。

We've got a smaller version that's blue and can be removed

我們有一個較小的藍色版本，可以拆卸，

and then we've got the larger version that's red.

還有一個較大的紅色版本。

Now when these things go onto the acrylic,

當它們扣在壓克力板上時，

they form an airtight seal because these are stretchy rubber gaskets. 片語搭配

會形成一個氣密密封，因為這些是彈性橡膠墊圈。

So I think they're going to work really well and I can't wait to put them to the test. 慣用語

所以我覺得它們會很好用，我都等不及要測試它們了。

Now since I know my cousin Ty had a chamber similar to this,

因為我知道我表哥 Ty 有一個類似的真空室，

I'm going to start off with the smaller one. 片語動詞

所以我打算先從小號的開始。

We're going to put it under vacuum pressure and let it sit for about 10 minutes.

我們會給它施加真空壓力，並放置大約 10 分鐘。

While it's doing that, we're going to set up the cameras and run away

在這期間，我們要架好攝影機，然後躲得遠遠的，

so that if it does implode, we're well out of harm's way. 慣用語

這樣如果它真的內爆了，我們也絕對安全。

Just for fun, I crunched up a water bottle and stuck the lid back on

為了好玩，我捏扁了一個水瓶並蓋上蓋子，

so we can put this inside the chamber

我們把它放進真空室裡，

so as we're drawing the vacuum, 用詞

這樣在抽真空的時候，

we can see how a crunched up water bottle reacts.

就能看看捏扁的水瓶會有什麼反應。

I'm just using a little bit of clay at the bottom

我在底部用了一點黏土，

to hold the bottle in place. 片語搭配

把水瓶固定住。

Pretty nice fit.

剛好合適。

The exhaust valve needs to be closed and the intake valve needs to be open

排氣閥需要關閉，進氣閥需要打開，

and we're ready to go.

我們準備開始吧。

So this is actually a pretty good sign, guys.

這其實是個好兆頭，夥計們。

This vacuum chamber has been running for about 5 minutes now

這個真空室已經運作了大概 5 分鐘了，

and I don't notice anything that's concerning.

我沒發現任何異常情況。

Very cool that our water bottle has fully inflated.

我們的水瓶已經完全膨脹了，太酷了。

And you can see on the gauge here,

大家可以看這裡的儀表，

the vacuum pressure has dropped down about as low as it's going to get. 文法

真空壓力已經降到了最低點。

So this is very encouraging, guys.

這讓人很受鼓舞，夥計們。

I've got the vacuum pump turned off and I've got both of these valves to the closed position. 文法

我已經關掉了真空泵，並且把這兩個閥門都關上了。

So in here, we still have a vacuum

所以這裡面仍然是真空狀態，

and you can see that because the bottle is still inflated.

你可以看出來，因為瓶子依然是膨脹的。

Now what do you think would happen if I open the exhaust port so air can get back in? 文法

現在，如果我打開排氣口讓空氣重新進入，你們覺得會發生什麼？

Let's watch the bottle and find out.

讓我們盯著瓶子看看吧。

I'm going to put my mask on for safety, though.

不過為了安全起見，我要戴上面罩。

Here we go in three, two, one.

準備，三，二，一。

How awesome is that?

簡直太帥了吧？

So the small jar worked and honestly that's what I was expecting,

看來小罐子成功了，老實說這也是我意料之中的，

but this here is the one that makes me a little more nervous. 文法

但這個大號的才真讓我有點緊張。

This is a lot more volume that we're sucking out.

我們要抽出多得多的空氣。

We just need to close the exhaust valve, open the intake valve,

我們只需要關上排氣閥，打開進氣閥，

get our safety measures in place and run away.

做好安全措施，然後趕緊跑。

Here we go!

開始了！

Takes a little bit longer to get the air out of that one.

抽出裡面的空氣需要更長的時間。

Probably because it's a bigger jar, huh?

可能是因為它的罐子更大吧，哈？

So it looks like the bottle's fully inflated.

看起來瓶子完全膨脹了。

Our gauge is down to about 25 inches of mercury 文化背景

我們的儀表顯示達到了約 25 英寸汞柱，

and surprisingly the glass seems to be holding up pretty well.

令人驚訝的是，玻璃似乎撐得很好。

At this point, I'm still pretty nervous to approach it though

此時此刻，我還是不太敢靠近它，

so let's just give it a few more minutes and see if it holds.

所以我們再等幾分鐘，看看它能不能撐住。

Okay guys,

好了夥計們，

this is actually working out really well. 片語動詞

效果其實非常好。

This is holding very nicely

撐得非常完美，

and it's very encouraging because now we have a big vacuum chamber

這很讓人振奮，因為現在我們有了一個大真空室，

that we can use to see really cool experiments happening inside.

可以用它來觀察裡面發生的酷炫實驗了。

The question though is how much pressure would it take to set this thing off? 片語動詞

不過問題來了，到底需要多大的壓力才能讓它炸掉？

Just joking.

開玩笑的。

I'm not going to do that in this video,

我不會在這個影片裡這麼做，

but if you guys want to see that, maybe we'll track down a slow motion camera and do that for a future experiment.

但如果你們想看，也許我們以後做實驗時會找台慢動作攝影機來拍。

Now just because this system hasn't imploded yet, doesn't mean that it won't. 文法

既然這個系統還沒發生內爆，不代表它絕對不會。

If there were any kind of hairline fractures in here, any weaknesses, 用詞

如果裡面有任何細微裂紋或薄弱環節，

it might just be a tap or a touch to set the whole thing off.

可能只需要輕輕一敲或一碰就能引爆整個裝置。

So I'm going to put my mask back on.

所以我還是把面罩戴上吧。

Let's open the safety valve and introduce the air back into the system.

讓我們打開安全閥，把空氣重新引入系統。

Yeah, and check this out.

耶，快看這個。

Now the lid comes off fairly freely.

現在蓋子可以很輕鬆地拿下來了。

What do you think would happen if we put a water bottle in there that we didn't squish the air out of?

你們猜，如果我們放進去一個沒擠出空氣的水瓶會怎樣？

Could we get it to explode? 文法

我們能讓它爆炸嗎？

Woah, look the water's boiling.

哇，看，水燒開了。

Woah!

哇！

But I guess it makes sense. 語氣意圖

不過我想這說得通。

We've lowered the atmospheric pressure in there so much 文法

我們大幅降低了裡面的大氣壓，

that the water has a new boiling point.

導致水的沸點也改變了。

Let's see what happens when we open the valve here.

讓我們看看打開這裡的閥門會發生什麼。

How cool is that?

是不是很酷？

So it must have sucked air out of the bottle as well. 文法

看來瓶子裡的空氣也被抽乾了。

These bottles won't burst until it gets closer to 60 or 65 PSI. 文化背景

這些瓶子直到壓力接近 60 或 65 PSI 才會爆裂。

So I'm going to pressurize one of these bottles with about 50 PSI

所以我打算給其中一個瓶子加壓到大約 50 PSI，

so when we remove the air, the pressure differential should be enough to get the plastic to burst. 講解

這樣抽走外部空氣時，壓差應該足以撐破塑膠。

So we got our purple bottle pumped up to 55 PSI 片語動詞

所以我們把紫色瓶子加壓到了 55 PSI，

and if we remove the atmosphere from the bottle now,

如果現在把瓶子周圍的空氣抽走，

hopefully that'll be enough for it to burst the plastic and give us a nice little explosion.

希望足以撐破塑膠，給我們來個漂亮的小爆炸。

Here we go.

我們開始了。

Do it.

爆吧。

Do it.

爆吧。

Dude, how much pressure can that take? 用詞

兄弟，它到底能承受多大壓力？

Huh, maybe it's not going to explode.

呃，也許它不會爆。

Yes!

耶！

I can't believe it finally worked!

簡直不敢相信，終於成功了！

So there we go.

好了。

Our bottle has finally exploded.

我們的瓶子終於炸了。

I was actually starting to doubt whether or not that would actually work or not. 文法

其實我剛才都開始懷疑它到底行不行了。

We tried that probably six times

我們大概試了六次，

and every time it would explode in my shop

每次它都在我的工作室裡炸了，

dang it rather than in the container.

見鬼，而不是在容器裡。

So there must be a very, very fine line. 慣用語

所以這其中的界線非常非常微妙。

I'm not sure why it would be so difficult,

我也不確定為什麼會這麼難，

but that one worked and that's all that matters.

但這次成功了，這才是最重要的。

And the other thing is the bottle exploded,

還有一點，雖然瓶子炸了，

but the container is still fully intact.

但容器依然完好無損。

So that kind of alleviates my concern because now we can see it can take a little bit of abuse and hold up. 講解

這算是打消了我的顧慮，現在我們知道它還是挺耐操的。

So that's good news.

這是個好消息。

Look at the bottle in there.

看看裡面的瓶子。

It's completely annihilated.

它徹底報廢了。

It's completely destroyed.

完全被毀了。

I think it's a combination of the pressure inside the bottle with the vacuum force

我覺得是瓶內的壓力和外部的真空吸力共同作用，

is pulling it out.

把它給扯壞了。

It just ripped that bottle to shreds. 慣用語

直接把瓶子撕成了碎片。

Man, it erupts with such power that it shakes the table 文法

天哪，爆發的威力大到連桌子都震動了，

and you can see the camera shake a little bit.

你們能看到攝影機也晃了一下。

That is a lot of power.

威力真大。

That's very cool.

非常酷。

So it looks like our vacuum chambers are holding up.

看來我們的真空室撐住了。

That's good news.

這是個好消息。

So there you have it, guys.

就是這樣了，夥計們。

The results are in. 慣用語

結果出來了。

Apparently, these glass cookie jars are a viable option for our vacuum chamber, 片語搭配

顯然，這些玻璃餅乾罐非常適合做我們的真空室，

which is really cool because now we can see inside the chamber

這真的很酷，因為現在我們可以看到容器內部，

as the reactions are taking place.

觀察反應發生的過程了。

And it doesn't hurt that we got a cool explosion out of the experiment as well. 慣用語

順便還在實驗裡看到了酷炫的爆炸，一舉兩得。
