Abstract
Abstract The disclosure is of a discus toy comprising a hollow disc on the sides of which are carried inflatable members, preferably of hemispherical configuration. Openings in the sides bring the interior of the disc into communication with the interiors of the inflatable members. Air scoops are provided on the periphery of the disc so that when the disc is thrown and spun, the inflatable members will expand into a sphere.
