1. An aerodynamic toy comprising, in combination, a body formed of a soft, flexible, homogeneous, thermoplastic, resilient, foam material having a circular peripheral edge, a central region having a higher density than the density at said edge, a substantially flat upper surface and a lower surface, said peripheral edge comprising a convex surface formed of said foam material defining an aerodynamic lift surface, said lower surface being recessed throughout said central region defining a rim of foam material adjacent said peripheral edge having a body thickness between said upper and lower surfaces greater than at said central region and a foam material density less than at said central region, the density of said foam material within said central region between the recess defined in said lower surface and said upper surface being greater than the density of said foam material within said rim, and an annular heat formed high density bead defined on said peripheral edge of said foam material, said bead maintaining the foam material adjacent said peripheral edge under compression to define said convex surface.
