Abstract: A light sword toy comprising a tube having a proximal end and a distal end, and a light source located at the proximal end of the tube. The light source directs light into the tube toward the distal end. The tube is made of a translucent material which glows when the light source is activated. A ball is contained within the tube, and is capable of moving between the proximal end and distal end thereof. When the ball is initially at the proximal end, it blocks nearly all of the light from the light source from reaching the distal end. When the ball is subsequently rolled toward the distal end, the illumination appears to travel toward the distal end. A ball retaining mechanism is located at the distal end for holding the ball at the distal end until the end of play. Then the ball is releasable by the user to restore the ball to the proximal end of the tube.
