Innovative – Gravitrax is a modular, electronic-free interactive track system where you can design and build your own race tracks and experiment with gravity, magnetism, and kinetics to propel your ball to the finish. Add stealth and surprise with 18 new elements. Straight, curved and vertical tunnels hide the marbles as they zip around the tracks. Test the Bernoulli and O-tracks to see how much speed you can generate and where you can drop a marble to a level below.
