Abstract
An aerodynamic toy adapted to be thrown through the air having a dish shaped body which is substantially hemispherical in shape and which has a rim integral with the body that provides balance and stability when the toy is thrown. The rim has upper and lower parallel surfaces that are substantially perpendicular to the axis of the body and a frusto-conical outer surface. The toy is sized to be grasped with the index finger and thumb extending about the body adjacent the rim in opposite directions and with the middle finger lying against the bottom of the rim.
