The magic of gravity pushes the spheres through the Geomag gravity motor spiral. A magical and eco-friendly system that uses the invisible forces of attraction and repulsion to set in motion the models. Starting at the base of the system, the weight of the spheres creates a never-ending spiral that kickstarts a real gravity motor. This set contains 11 magnetic rods, 32 spheres and 126 plastic mechanical elements. Gravity is the innovative evolution of the Geomag mechanics line. Developed with expert players in mind, the new construction system is based on an innovative "gravity motor": this uses the weight of the Geomag spheres to Kickstart the mechanisms and movements of the Geomag mechanics structures. The motion is provided by the invisible forces of gravity and magnetism, without using electricity or batteries. The play experience is based on these fundamental principles of physics. Mechanics gravity is a STEM product that can truly stimulate curiosity and inspire to learn more about science.
