The gravitrax starter set from Ravensburger offers everything you need to begin building your own action-packed track systems. Discover how the laws of physics affect the track your ball takes with curves, crosses, freefalls and even a cannon. Experiment using different heights and angles to control the speed of the ball.
Gravitrax are my goto construction set! The sleek tracks, fun circuits and numerous course options help take marble runs to the next level for repeated fun! -Armondo
This is the perfect gift for a child who likes building things. There are so many ways to build, it never gets old! For us science nerds it’s a great way to have discussions about gravity and force! -Katie
