Abstract: A game ball is disclosed herein having an inflatable bladder or shell with selected portions thereof reduced in thickness to provide transparent or translucent patterns separated by increased thickness to provide opaque portions. The interior of the ball is occupied by a breakable liquid illumination device held in a removable housing of transparent or translucent material for conveying illumination from the device to the selected portions of the ball thereby transmitting the illumination exteriorly of the ball for visual observation. The apparatus may include ancillary components, such as hoops or nets, which may support an elongated illumination device so that the visual glow from both the ball and component may be correlated during the play of a game.
