A ping pong ball and a penny are placed in water. The ping pong ball floats while the penny sinks? What property of water does this demonstrate?

I think it has to do with the density. The reason the ping pong ball floats is because it has a lower density than the water. The penny sinks because it has higher density than water. Am I correct? Is there another property of water that I need discuss related to density?
Answered by Damon
yes, the mass per unit volume is greater than water for the penny and less than water for the ball.
