• Harnesses the invisible forces of magnetism and gravity in Geomag Mechanics Gravity! • An innovative \'gravity motor\' uses the weight of the Geomag spheres to kickstart the mechanisms and movements! • Motion is provided by the invisible forces of gravity and magnetism, without using electricity or batteries! • Encourages fine motor skills and creativity and imagination! Swiss made Geomag Mechanics Gravity is based on an innovative \'gravity motor\' which 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 magnetic track harnesses the invisible forces of magnetism and gravity through original and surprising means. The spheres inside the circuit are set in motion by an innovative magnetic cannon that uses the force of attraction of the accelerating magnet. This STEM product is designed to encourage fine motor skills, learning by playing and creativity and imagination. Geomag is the original magnetic construction toy.
