GraviTrax Element: Magnetic Cannon — Magnet‑Powered Launcher (includes 3 marbles)

Launch marbles through your run with the GraviTrax Magnetic Cannon. Place two marbles in front of the cannon; when the trailing marble strikes, the front marble is blasted down the track by a high-powered magnet, giving it a burst of speed to help overcome inclines and continue along the layout. A strong addition to any GraviTrax Starter-Set; this unit comes with 3 additional colored marbles. GraviTrax sets are electronic-free, STEM-friendly and entirely modular — encouraging imagination, critical thinking and problem-solving while providing open-ended play and expandable options.
