Ravensburger GraviTrax Starter Set

This is the GraviTrax Starter Set, which is a really cool way to get into building your own marble runs. It's an interactive track system where you can design and build your own race tracks and experiment with gravity, magnetism, and kinetics to propel the marbles to the finish. It comes with over 100 pieces, including various tiles, levels, and tracks to keep things interesting. New in the box.
