Aerodynamic throwing toy

Abstract

Disclosed is an aerodynamic throwing toy having a general geometry of a shape formed by taking a sphere of a desired radius, with a disc of a desired height removed from the sphere's equatorial region. The remaining partial hemispherical portions are rejoined along their respective base sections. The resulting toy is round from a plan view, and has an edge, visible in a side view. The toy rotates about the center of its joined partial hemispherical portions while in flight. The toy can be thrown like a baseball, can spin while in flight, and can usually be caught with one hand. The height of the disc can be determined from a predetermined angle of latitude of the sphere. The aerodynamic throwing toy can have dimples disposed circumferentially about the toy. The toy can have various graphics, designs or patterns disposed on the outer surface of the toy.
