Abstract:
An aerodynamic flying disk, which comprises:(a) a circular disk body having a topside formed by a top wall and a circumferential rim and an underside formed by an interior cavity underlying the top wall and inside the circumferential rim, the disk body capable of being thrown by gripping the circumferential rim of the disk body and by throwing and spinning the disk body to cause the disk body to fly through the air; (b) a circular groove on the topside of the disk body extending substantially 360Â° around the disk body; and (c) at least one light stick that produces light using a chemical light producing reaction when the light stick is selectively bent and snapped, wherein the light stick is removably retained in the circular groove on the topside of the disk body by a frictional press fit such that the light stick can be installed in the groove after the light producing reaction has been initiated and can be removed from the groove after the light producing reaction is spent, the light stick when installed in the groove being visible from the topside of the disk body without the light stick being obscured in the interior cavity forming the underside of the disk body.
