Abstract
A pneumatic playball which emits a series of strobe-like light flashes each time the ball is bounced by a player. The playball includes a spherical casing formed of flexible, translucent plastic material having internal plugs at the opposing poles of the sphere. Suspended between the polar plugs along the diametrical axis of the spherical casing is a light-flashing unit. The unit includes at least one light-emitting diode (LED) connected to a battery through an electronic blinker which each time it is activated, yields a series of voltage pulses which is applied to the LED to produce a series of light flashes. Activation of the blinker is effected by a motion sensing switch which closes to activate the blinker only when the ball is bounced or otherwise undergoes an abrupt change in velocity.
