瞬間結冰 - 技巧、訣竅與注意事項！：英語精讀講義

What would your friends say on a hot summer's day if you could open up a bottle of water 文法

如果在炎熱的夏日，你能打開一瓶水，

and pour out an instant snow cone? 片語動詞

然後直接倒出一份「速成冰沙」，你的朋友們會怎麼說呢？

In this project,

在這個專案中，

we're exploring some tips,

我們將探索一些技巧、

some tricks,

一些竅門，

and everything else you'll need to know

以及你需要知道的一切，

to master the art of making instant ice. 片語搭配

讓你掌握製作「速成冰」的藝術。

In a previous video,

在之前的影片中，

we turned water like this

我們把像這樣的水，

directly to ice in just an instant.

在瞬間直接變成了冰。

For this project,

對於這個專案，

you'll just need some purified water,

你只需要一些純淨水，

and the easiest place to find that

而最容易找到它的地方，

is in a water bottle.

就是瓶裝水。

Go ahead and throw about six bottles in the freezer

儘管去冷凍庫裡放上大概六瓶水吧，

because the more bottles you start with, 文法

因為你開始用的瓶子越多，

the better chances you're going to have for success.

你成功的機率就越大。

The temperature dial in my freezer was set to 5 of 7,

我家冷凍庫的溫度旋鈕設在了7段中的第5段，

and that settled to a temperature of -24 °C

它的穩定溫度是-24 °C，

or around -11°F.

或者大約-11°F。

Now, these bottles have been sitting at room temperature overnight, 文法

現在，這些瓶子已經在室溫下放了一整夜，

and in my experience,

而且根據我的經驗，

this trick works best if they're evenly spaced

如果它們間距均勻

and placed on their sides.

且平躺放置，這個技巧的效果最好。

The minute the door closes,

關上冰箱門的那一刻，

make a note of the time. 片語搭配

記下時間。

After an hour and a half,

一個半小時後，

check your bottles to see if any of them have frozen.

檢查一下你的瓶子，看看有沒有結冰。

If they're all still liquid,

如果它們都還是液體，

then quickly close the door,

那就趕緊關上門，

but keep checking on them every 15 minutes. 片語動詞

但要每15分鐘檢查一次。

For these particular bottles,

對於這批特定的瓶子，

it took 2 hours and 45 minutes for the first one to freeze. 文法

第一瓶結冰花了2小時45分鐘。

Looking at the bottle,

看著這個瓶子，

you can see it's not frozen solid, 片語搭配

你能看出它沒有凍得硬梆梆的，

but you should see flakes of ice floating around under the plastic.

但你應該能看到塑膠瓶下有碎冰在漂浮。

At this point,

這個時候，

stop and take note of the time.

停下來，記下時間。

Then subtract 15 minutes,

然後減去15分鐘，

and now you have a supercooling formula

這樣你就得到了一個過冷水公式，

for your favorite brand of water.

適用於你最喜歡的水品牌。

In my case,

在我的情況下，

this trick works from 2 and 1/2 hours

這個技巧在2個半小時

to 2 hours and 45 minutes.

到2小時45分鐘之間起效。

Now, if the bottles in the freezer haven't frozen yet,

現在，如果冷凍庫裡的瓶子還沒結冰，

take them out very gently.

非常輕柔地把它們拿出來。

This water is well below freezing, 用詞

這些水的溫度遠低於冰點，

but hasn't frozen yet because there aren't any impurities to get it started. 文法

但還沒有結冰，因為沒有雜質來觸發結冰過程。

The water does want to freeze,

水其實是想要結冰的，

and that's why something as simple as a jolt to the side 文法

這就是為什麼只需往側面輕輕一敲，

can be enough to nucleate the ice formation, 用詞

就足以成為冰晶形成的凝結核，

and just like magic, 慣用語

就像變魔術一樣，

you've got instant ice.

你得到了速成冰。

You'll notice that bottles this cold will develop a layer of condensation,

你會注意到，這麼冷的瓶子表面會結一層水氣，

making it harder to see inside. 文法

讓你很難看清裡面。

So, go ahead and wipe that off. 講解

所以，儘管把它擦掉吧。

This way, when you hit it,

這樣，當你敲擊它的時候，

you'll have a much better view of the crystal formations.

就能更清楚地看到冰晶的形成了。

Another way to start your water freezing 文法

另一種讓水開始結冰的方法，

is to use a piece of ice.

是用一塊冰。

Put the ice anywhere you want,

把冰放在任何你想放的地方，

and then pour your water over top.

然後把水倒在上面。

You should see it freeze instantly

你應該能看到它瞬間結冰，

and build quickly into instant ice sculptures like these.

並迅速堆積成像這樣的一座速成冰雕。

I put an ice cube on this rock,

我在這塊石頭上放了一塊冰塊，

and you can see the crystals build every time

你可以看到，每次

the water makes contact with the ice. 片語搭配

水接觸到冰塊時，冰晶就會堆積起來。

You could make this easier by using a whole bowl of ice. 文法

你可以用一整碗冰，讓這變得更簡單。

Now, if you start pouring your water,

現在，如果你開始倒水，

and it doesn't look like it's building pillars very quickly, 文法

但它看起來並沒有很快地堆積成冰柱，

it means your water hasn't cooled enough

這意味著你的水還沒有冷到足夠的程度，

and probably needs another 5 to 10 minutes in the freezer.

也許需要在冷凍庫裡再放5到10分鐘。

This bottle did come out 10 minutes later, 文法

這瓶水確實是10分鐘後拿出來的，

and you can see a dramatic difference in how quickly it freezes.

你能看到它結冰的速度有了驚人的不同。

If you leave your bottles in the freezer too long,

如果你把瓶子在冷凍庫裡放得太久，

they may be so sensitive that even wiping the side 文法

它們可能會變得非常敏感，甚至只需擦一下瓶子側面

of the bottle initiates the freeze.

就會開始結冰。

And it could be complete before you even get the cap off. 片語動詞

而且甚至在你打開瓶蓋之前，它可能就全凍住了。

If you do get the cap off,

如果你確實打開了瓶蓋，

pouring too slowly might result in this effect 片語搭配

倒得太慢可能會導致這種現象：

where the water doesn't pour out at all, 文法

水根本倒不出來，

and that's because it iced up in the bottleneck, 片語動詞

那是因為水在瓶頸處結冰了，

and it's freezing the rest of the way down.

並且一直向下凍到底。

If you're wondering how cold the water actually is, 表達脈絡

如果你好奇這水到底有多冷，

I was able to measure one bottle at -4.5 °C,

我測出其中一瓶是-4.5 °C，

and there's a good chance they're actually colder than that. 片語搭配

而且它們很有可能比這還要冷。

If you try pouring this supercooled liquid into a glass,

如果你嘗試把這種過冷液體倒進玻璃杯裡，

you might notice it looks a little thick and syrupy.

你可能會注意到它看起來有點濃稠、像糖漿一樣。

If you get to this point,

如果你到了這一步，

try touching the surface gently with an ice cube.

嘗試用一塊冰塊輕輕觸碰水面。

Everything freezes firm enough to hold the ice cube in place 講解

所有的東西都會凍得很結實，足以把冰塊固定住，

and makes a nice little platform to continue building your ice towers.

並且為你繼續搭建冰塔提供了一個不錯的小平台。

When trying this approach, 文法

在嘗試這種方法時，

it's important that the glass is extremely clean

玻璃杯必須非常乾淨，這一點很重要，

because even a microscopic impurity can trigger the nucleation

因為即使是微小的雜質也能引發凝結，

and solidify your experiment prematurely.

讓你的實驗過早凝固。

You could try using this effect to pour yourself an instant snow cone.

你可以嘗試利用這個效果，給自己倒一份速成冰沙。

As the water freezes,

當水結冰時，

it actually releases latent heat in the reaction 用詞

它實際上會在反應中釋放潛熱，

and warms the ice into a delicious slush.

並將冰稍微加熱成美味的冰沙。

I tried using the juice in these freeze pops

我嘗試過用這些冰棒裡的果汁

as a makeshift snow cone syrup 用詞

來作為臨時的冰沙糖漿，

and poured it on top to get three different flavors.

把它倒在上面，得到了三種不同的口味。

Well, now you know everything you need to know 表達脈絡

好了，現在你已經知道了一切你需要知道的

about making instant ice.

關於製作速成冰的知識。

If you want to see colored crystals,

如果你想看到彩色的冰晶，

try pouring two drops of food coloring

可以在冷凍前

in the water before you freeze it.

在水裡滴兩滴食用色素。

Well, that's it for now.

好了，這次就到這裡了。
