Abstract
A hand propelled circular air glider or flying saucer type aerodynamic toy. The toy includes a solid upper disc portion and a concentric, substantially larger lower annular disc portion having an aperture therein approximately equal to the diameter of the upper disc portion. The upper disc portion and lower annular portion are disposed generally parallel and are connected together by a plurality of radially directed, generally trapezoidal, evenly spaced fins. A depending, short cylindrical flange circumscribes the outer perimeter of the lower annular portion to stabilize the flight of the toy as it precesses through a gaseous medium.
