ABSTRACT:
An aerodynamic toy is provided for use in throwing games. The toy is shaped somewhat like a saucer and its body is provided on its convex sides with radial elevations. These provide discontinuities to the flow of air so that in use the air flow over the convex surface of the aerodynamic toy is disrupted thereby creating a turbulent air layer over the moving surface and reducing aerodynamic drag. An openable central compartment on the concave side may be used to contain batteries and a switch to power lights. The latter are supported by clips near the rim of the saucer.
