All balls will bounce based on the surface you bounce it on. Even a bowling ball will bounce at least a centimeter or half a centimeter even though it is hard to determine whether it is getting off the ground or not. Of course it wont bounce if you bounce it on something soft and break through, but it will bounce on a hard cement floor. It will bounce because it will have potential energy weighing it down and if the floor is harder than the ball, the ball will move off like opposite sides of a magnet. but only for a while until our gravity pulls it down and stops it. Hope that helped.
