1. A game ball comprising an outer layer of a first material having a generally spherical cavity therewithin, said layer having a substantial radial thickness, and an inner generally spherical core of a second material, means for enabling said inner core to move within and relative to said cavity when subjected to a force exerted thereagainst, said first material possessing a lesser density and a greater degree of compressibility than said second material, and the dimensions of said core corresponding to the dimensions of said cavity when neither of said materials is compressed, whereby when the exterior of said layer is impacted to compress said first material at one side of said core to exert said force against said core, said core shifts within said cavity to momentarily compress said first material at the other side of said core and at the same time to deform said cavity to avoid splitting said outer layer.
