Very similar to the magnetic ballistics car, yet with a trigger that can be operated with a remote control. As the car propels foward, shoot the ball out of the barrel from across the room using the included remote. Marvel as the ball is caught again by the moving car! With a smoother run and less friction than our prior design, this unit includes a car with barrel: 25mm steel ball: trip that operates by remote control: remote controll unit and instructions.
