【英语时差8,16】虫子是如何浮在水面的？-上

It’s summertime, and you’re on vacation. You sit beside a quiet pond, fishing, trying to relax, trying to think about nothing at all. You watch the leaves stirring, the water rippling¹ in the sunshine, and the water bugs² standing³ on the surface of the water. There are two things involved in this trick: one is a property of the water, and the other has to do with the bug’s feet. Let’s start with the water. Water molecules⁴ naturally stick to each other, due to a strong chemical attraction between the individual molecules. At the pond’s surface, the uppermost water molecules experience this attraction as a strong pull toward each other, and downward from the water beneath them.
