Density ball in cold/warm water

Put warm water in one beaker and cold water in the second beaker. Place the ball in the beaker of cold water first. Note that it floats, due to its density. Then place it in the beaker of warm water and note that it sinks. The ball's density is between that of cold and warm water.
