Gravitrax Marble Run Construction Toy Starter Kit - Ravensburger
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 gravity sphere to the finish. With a variety of tiles, levels, tracks and features you can control the speed of each gravity sphere.
The open-ended building concept offers endless possibilities to design a different track every time you play. Experience the power of gravity with GraviTrax.
With over 100 pieces and 18 different construction elements, the GraviTrax Starter Set offers everything you need to begin building your own action-packed track systems. Discover how the laws of physics affect the path your gravity sphere takes by adding curves, crosses or even a cannon to your track. Experiment using different heights and angles to control the speed of the gravity sphere.
The included tasks and construction plans introduce you to the world of GraviTrax. Let your creativity take over and construct your own track designs from scratch.
