  • a hollow, lightweight, translucent plastic spherical shell,said shell having a substantially imperforate portion,said shell further having a plurality of closely spaced perforations extending therethrough and providing a perforated zone characterized by surface openings,all said perforations and openings being grouped in one portion of said ball surface to cause the wind-resisting characteristics of the surface of said ball to vary unsymmetrically, whereby said ball when spinning in flight will follow a curved path,said shell further having disposed therein a ring-shaped, chemiluminescent light stick which, when activated, enables said ball to be sufficiently visible for play at night.
