Abstract
A throwing disc with changeable aerodynamic characteristics for use with human hands having fingers, comprising a first member which is circular and has a diameter and a thickness substantially less than the diameter of the first member. The first member has first and second surfaces and has an outer margin and a downward depending lip adjoining the outer margin. A second member is centrally disposed with respect to the first member. The first and second members are interconnected so the first and second members can move in unison as the throwing disc is thrown. The second member is movable with respect to the first member for changing the aerodynamic characteristics of the throwing disc.
