Regulation balls must weigh 8-16 pounds (3.6-7.2 Kg) and have a diameter of 8.5 inches (21.6 cm). Since the physical size of regulation balls is the same, while the weight may differ, lighter balls are much less dense than heavier ones. Thus, 8-10 pound balls will actually float when placed in water.
