Why doesn’t sand stick to beach volleyball players?

Why doesn’t sand stick to beach volleyball players? | - Yahoo! Sports:

The sand used in competition is heavily regulated by the International Volleyball Federation. There are no pebbles or bits of shells. The shape ensures a smoother grain. The size is Goldilocks style: not too small or too big. Why doesn't it stick? Because it's designed not to.

Interesting! I never noticed this before.
