The Lifter Expansion Set takes your marble run experience to a whole new level with over 25 additional elements. Once the marble reaches the bottom, raise it up to 3 levels higher using the Lifter accessory: a button-operated elevator. Experiment with additional tracks, height tiles, and one transparent level. Combine with the GraviTrax® Starter Set and test your skills to see how long you can keep the marbles rolling.
GraviTrax is a modular, electronic-free interactive track system where you can design and build your own marble runs. This STEM toy for boys and girls 8 and up, encourages experimenting with gravity, magnetism, and kinetics to propel your marble to the finish. Designed with open play in mind, the concept offers endless possibilities to design a different track every time you play. Expand your builds and add some action with a variety of expansion sets and accessories.
