The GraviTrax Magnetic Cannon element uses a strong magnet to turn a simple collision into a boosted launch. Place two marbles in the cannon lane and send a third rolling in and its impact triggers the front marble to shoot ahead with enough momentum to tackle uphill sections or longer stretches of track. The set includes the magnetic cannon base plus three extra colored marbles, giving builders more options for timing tricks and multi marble runs.

Compatible with all other GraviTrax sets!
