GraviTrax Starter Set - STEM Marble Run Toy | Curious Kidzz

Gravity, Magnetism, Kinetic Energy — The Ultimate STEM Marble Run System!

Experience the power of gravity with the Ravensburger GraviTrax Starter Set! Featuring over 100 components, this innovative marble run system allows young engineers to design, build, and test their own action-packed track layouts. Using principles of gravity, magnetism, and kinetic energy, players guide their gravity spheres through twists, junctions, drops, and speed-boosting cannons to reach the finish line. It’s open-ended, screen-free, and endlessly expandable — the ultimate interactive physics playground.

With a modular design, kids can experiment with height, angle, and speed adjustments to overcome obstacles and master track building. Guided by included task cards or driven by pure creative freedom, GraviTrax offers an exhilarating hands-on STEM experience that keeps minds sharp and problem-solving skills active.
