Water level (Posted on 2003-03-10)

I’m sitting in a boat in a pool. In the boat with me is a cannonball. What happens to the level of the pool if I take the cannonball out of the boat and drop it into the pool? Does the level increase, decrease or stay the same?

The level drops.

More water is displaced when the cannonball is in the boat than when it is in the water.
