Abstract
A football having an end appendage comprising at least one long, narrow strip of a flexible sheet material, e.g., cloth of flexible plastic, which functions as a tail when the ball is thrown or kicked and which provides directional stability for the football while in flight. When multiple strips are used which are formed of a rigidly flexible sheet such as MYLAR, the appendage also functions as a sound generator. When the football is thrown in a normal manner, the tail extends backwards, providing a slight drag to cause the back tip of the ball to align itself with the front rip, thereby resulting in the straight and accurate flight of the ball. One end of the appendage is preferably detachably/attached to an end of the football by interlocking hook and loop material, commonly known as VELCRO.
