Abstract
Abstract An improved aerodynamic toy for being thrown through the air in a spinning motion is disclosed. A centrally located body in the form of a many sided pyramid is attached to the circular base or saucer portion of the aerodynamic toy. The spinning motion of the aerodynamic toy enables the centrally located body to perform a number of aerodynamic functions which improve the flight performance of the aerodynamic toy. In the preferred embodiment, the centrally located body is a four sided square bottomed pyramid having an elevational profile higher than the rim and saucer portion of the aerodynamic toy.
