Give your marble run a magnetic boost! When a marble rolls into the Magnetic Cannon, magnetic force transfers its energy and shoots another marble out the other side at high speed. It is a great way to restart momentum on long runs and a hands-on way to explore magnetism and energy transfer. Requires a GraviTrax Starter Set (sold separately).
