Abstract
A ball for use in playing street hockey having a substantially smooth spherical shell with a hollow interior cavity partially filled with a liquid and a plurality of prills to less than one-half of the volume of the interior cavity. The specific gravity of the prills is less than that of the liquid to minimize splash of the liquid and to improve the ability of the liquid to remain in the lower portion of the ball as it travels over a playing surface.
