ABSTRACT:
A practice ball comprised of mutually perpendicular X-, Y- and Z-members. A plurality of wings interconnect the X-, Y- and Z- members. The shape of said wings skeletally defines the shape of the practice ball. The wings and reduced weight of the practice ball provide for a shorter trajectory for the practice ball than the equivalent standard ball (golf, tennis, etc.), thereby allowing smaller playing fields to be used. The practice ball may be manufactured by means of an injection molding process, and produces a pleasant whirring sound in flight.
