With the GraviTrax interactive track system, you can design and build your own race tracks, and experiment with gravity, magnetism and kinetics to propel your marble to the finish. The open-ended building concept offers endless possibilities, to design a different track every time you play. Add speed and flair to your tracks with expansion sets and action accessories for endless hours of fun both young and old will enjoy!
Add some speed to your GraviTrax circuit with the Hammer expansion. If your marbles are decelerating, this hammer will launch them through your track with some much-needed velocity. This accessory also includes six additional tracks. GraviTrax Starter Set required.
