The National Geographic 95-Piece Motorized Marble Run Set is a super-fun way for kids to explore construction, engineering, and physics! Configure the pieces in any design you’d like and explore endless marble maze possibilities! The motorized lift keeps the action moving, creating a perpetual motion machine that keeps the marble action going non-stop! The pieces in this kit--including the motorized lift--are compatible with existing National Geographic Glow-in-the-Dark Marble Run kits (non-magnetic), allowing you to explore even larger runs! The detailed Learning Guide has lots of information about the physics of motion and gravity, so kids can learn while they play! And when they’re all done, a convenient storage bag is included so you can keep all the marble run pieces stored together.
