Wet rocks

Imagine you're sitting on a floaty in a pool.  You have a rock in your hand.  What will happen to the level of water in the pool if you let the rock sink to the bottom of the pool?  Think about it, leave your guess in the comments and follow the link for the answer.  Then read my post about making predictions!
Don't read this until you've made your guess!
