Abstract
A tetherable game ball is provided that includes a resilient hollow ball (48) having an aperture (52) through which a line (54) having two ends extends therethrough to a position within the hollow ball (48) to form a loop located exteriorly of the ball (48) for allowing a tether to be secured thereto. Each end of the line (54) that is located within the hollow ball (48) forms a knot (56, 58) for restraining the line (54) from being pulled through the aperture (52). The game ball can be constructed so as to have rebound and elastic properties similar to those of a racquet ball.
