this trick works best if they're evenly spaced

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

At this point,

这个时候，

stop and take note of the time.

停下来，记下时间。

Then subtract 15 minutes,

然后减去15分钟，

and now you have a supercooling formula

这样你就得到了一个过冷水公式，

for your favorite brand of water.

In my case,

在我的情况下，

this trick works from 2 and 1/2 hours

这个技巧在2个半小时

to 2 hours and 45 minutes.

到2小时45分钟之间起效。

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

现在，如果冰箱里的瓶子还没结冰，

take them out very gently.

非常轻柔地把它们拿出来。

This water is well below freezing, 用詞

这些水的温度远低于冰点，

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

但还没有结冰，因为没有杂质来触发结冰过程。

The water does want to freeze,

水其实是想要结冰的，

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

这就是为什么只需往侧面轻轻一敲，

can be enough to nucleate the ice formation, 用詞

就足以成为冰晶形成的凝结核，

and just like magic, 習語

就像变魔术一样，

you've got instant ice.

Another way to start your water freezing 語法

另一种让水开始结冰的方法，

is to use a piece of ice.

是用一块冰。

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.

然后把水倒在上面。

You should see it freeze instantly

Now, if you start pouring your water,

现在，如果你开始倒水，

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

it means your water hasn't cooled enough

If you do get the cap off,

如果你确实打开了瓶盖，

pouring too slowly might result in this effect 短語搭配

倒得太慢可能会导致这种现象：

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

水根本倒不出来，

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

那是因为水在瓶颈处结冰了，

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

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

When trying this approach, 語法

在尝试这种方法时，

it's important that the glass is extremely clean

玻璃杯必须非常干净，这一点很重要，
