The movement of the mechanics models wins over gravity with the gravity shoot & catch set. Thanks to the magnetic motor, the Geomag spheres move up along a never-ending spiral and reach a circuit of amazing magnetic tricks. Here is the "stop&go" trick in action: two magnetic rods, positioned with opposite polarities, can keep one or two spheres perfectly still inside a chute. When a third sphere joins the other two from above, it is itself trapped by the magnet and the lowest positioned sphere is released to continue its journey along the circuit. This gravity set contains 11 magnetic rods, 36 steel spheres and 196 plastic mechanical elements. These gears are essential to harness the forces of gravity and magnetism. 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.
