The ball shooter is used to fire the small particle balls in order to score points.  The ball uses the conveyer belt to lift the balls up a Lexan slide.  At the top of the slide are two AndyMark motors spinning out in opposite directions. The motors have a gearbox with a 4:1 ratio. When a ball reaches the top, it is pushed in between the spinning wheels attached to the motors. This is what causes the balls to be fired into the air.
