Okay. Do you remember the weirdest property of solid water?

你还记得固态水最奇怪的特性吗？

This is what solid water, ice, looks like on the molecular level.

固态水、 冰、从分子图上是这样的。

But solid water, a. k. a. ice, is somehow less dense than liquid water.

但是，不知为何，固态水，又称冰，密度比液态水小。

The ice or snow was solid water. The heat changed it into liquid water, such as we drink.

冰和雪都是“固态”水。热量让固态水变成了“液态”水，就是我们喝的水。

Tom soon found that he could run about on the solid water, and very quickly he ran across the pond and claimed his penny.

汤姆很快发现, 他可以在凝固的水上来回跑了。他飞快地跑过池塘, 挣到了那个便士。
