GRAVITRAX SYSTEM MARBLE RUN MACHINE KIT
Monster GRAVITRAX starter track system. Like a (100)-piece slice of heaven for STEM kids, it teaches them (or adults, actually) about gravity, magnetism, kinetic energy and fun. Includes projects and blueprints, plus base cards, transparent levels, a magnetic cannon, long/med/short rails with curves and intersections, Y-points, vortex and a bunch more, all compatible with all GRAVITRAX expansion packs and add-on sets.
