ABSTRACT:
An improved ball for use in playing tetherball games is characterized by its construction of unitary seamless resilient material, such as rubber, having an oval shape when at rest and having holes at opposite ends of the smaller axis of the ball. Through the smaller of these holes a cord is attached to the ball, preferably by means of a stop introduced into the interior of the ball by way of the larger hole. The stop has a passage extending axially through it through which a suspension cord or tether is passed. The larger hole is left open to the air, and thus imparts superior cooling properties to the ball which enhances its longevity. The exposure of this hole to the air also provides a whistling sound as the ball orbits thereby providing an added element of enjoyment to the game in which the ball is used. Further, by being attached to the suspension cord on the smaller axis of the ball, the ball in orbiting when struck tends to assume a spherical shape due to the centrifugal force exerted on it during play.
