An aerodynamic toy of a generally flat circular configuration adapted to glide through the air when thrown with a rotational movement imparted thereto, the configuration producing an aerodynamic lift, and the material of the toy consisting of a flexible, resilient polyurethane foam wherein the foam density in the central regions is slightly greater than at the peripheral region, and a recess is formed on the underside. The configuration of the body in conjunction with the recess producing aerodynamic lift, and the body material permitting the toy to be used indoors.
