Ravensburger GraviTrax expansion rope tracks

The Gravitrax extension set with slide rope allows the marbles to travel long distances and connect different tracks. The rolling marble initiates the movement. The marble glides to the finish line and pushes the next marble forward.
The set is based on the STEM system [science, technology, engineering, and mathematics], making it ideal for teaching children about gravity, magnetic phenomena, and kinetic energy in a fun way.
The GraviTrax track system can be endlessly expanded with additional track pieces and other accessories.
Compatible with all GraviTrax products.
The game box includes: 4x building blocks, 2x U-shaped support posts, 2x base blocks, slide wheel, slide lever, 2x slide beam fixation, 2x slide beams, and instructions.
