There’s no need to go ballistic trying to find a way to demonstrate concepts of forward motion. When the Ballistics Car is pushed, the steel ball ejects from the spring-loaded barrel. The ball falls back into the barrel of the moving car, showing that the ball’s forward motion is the same as the vehicle from which it was ejected – a simple but effective demonstration. Includes a steel ball, release pin, and cord. Choose from one of two different heights of ball flight.
