Abstract
A projectile launcher is provided for propelling impact-safe foam projectiles. The projectile launcher includes a launch tube sized and configured to accommodate insertion of an impact-safe projectile with substantially little or no friction between the launch tube inner wall and the projectile. A nozzle is disposed adjacent one end of the launch tube. The nozzle is adapted to receive a flow of compressed air from a source and to discharge a stream of high-velocity air which impinges upon the projectile disposed within the launch tube. A play-participant-actuated valve is interposed between the nozzle and the source of compressed air to control the flow of air to the nozzle. The valve is adapted, when actuated, to place the nozzle in communication with the source of compressed air. Upon actuation of the valve the nozzle discharges a stream of high-velocity air which transfers momentum to the projectile, propelling it down the launch tube and into the air or at a selected target.
