Water drops bounce when they hit

The video has an explanation for why a water drop doesn't fall into a puddle smoothly. Instead, the air under the drop gets compressed, and is enough to support the drop briefly. Enough air gets forced out that some of the drop falls into the puddle. And then the surface tension goes sproing! and bounces what's left of the drop into the air. This repeats a few times until the drop is used up.

I can only hope that someone is inspired to figure out how to get the maximum number of bounces.
