1. A compound ball for simulating the performance of a regulation size ball for the playing of a sport, comprising an outer shell and an inner shell dimensioned to provide a spacing between the outer and inner shells, the outer shell being spherical and formed of molded polymeric material and defining circular apertures spaced over the surface of the outer shell, the inner shell being gas filled and comprised of a material capable of resiliently rebounding in response to being compressed by the outer shell upon deformation of the outer shell in response to being hit, the apertures in the outer shell permitting air to pass through the apertures when the compound ball is in flight, the inner shell providing mass and impact rebound within the outer shell for simulating the action of a regulation ball when thrown, caught, hit or impacts an object.
