GraviTrax is a modular marble run system designed for children ages 8 and up, compatible with all GraviTrax and GraviTrax PRO components. The Flip'n'Dip Action-Set includes over 100 pieces, featuring hexagonal base plates, rails, curves, and elevation blocks. The set introduces two CORE Elements: the Flip, which propels marbles upward and reverses their direction by 180 degrees, and the Dipper, which guides them smoothly downward. These mechanics allow marbles to traverse multiple levels, gaining momentum for continuous motion. The set comes with pre-designed track layouts for easy setup while encouraging open-ended building. All GraviTrax components are interchangeable, offering flexibility for creative track designs.
