With 67 pieces, the Geomag Mechanics Gravity Race Track offers a physical construction experience. This marble run uses the forces of gravity and magnetism to set the included spheres in motion. Thanks to the integrated magnetic cannon, the spheres are accelerated without electricity or batteries, while parabolic curves ensure dynamic changes of direction. The set is made of 76 percent recycled plastic and is manufactured in Switzerland. It playfully promotes the understanding of STEM principles and can be flexibly combined with other sets from the Mechanics line.
