Ravensburger GraviTrax Power Extension Interaction – STEM Marble Run

Power Up Your GraviTrax Marble Runs

Transform standard marble plays into energized, exploratory challenges with the Ravensburger GraviTrax Power Extension Interaction. This expansion adds a dynamic power feature that lets you influence speed and trajectory as marbles race through gravity, magnetism, and kinetic elements. Designed to integrate smoothly with existing GraviTrax sets, it invites hands-on experimentation and thoughtful planning, making each build a fresh puzzle to solve.

With 13 additional pieces, this extension extends playtime and unlocks new design possibilities. The interactive system encourages players to test different routes, measure outcomes, and refine strategies—perfect for curious minds who enjoy constructing and observing how small changes alter performance. The expansion complements the core GraviTrax experience by adding electronic elements that heighten the sense of control without complicating setup.
