Puddle's Great Escape
Why do puddles disappear?
You step in a puddle on Monday morning — splash! — and by Tuesday afternoon, it's gone. No one drank it. No one mopped it up. Where did all that water go?
Water molecules are incredibly tiny — millions of them in a single drop. And they're restless. Even when the puddle looks perfectly still, those molecules are vibrating and bouncing around like popcorn kernels on a hot stovetop.
