Explore the world of the magical invisible forces of magnetism and gravity with this 183 piece set.
This innovative evolution in the Geomag Mechanics line has no need for electric or battery motors. Swiss-made from 90% recycled plastic, this clever construction uses the weight of the metal balls to trigger movement in the construction, getting faster as you load the magnetic spheres. A truly STEM product, stimulating all levels of scientific exploration and a fascinating build project for inquisitive minds. Magnetic fun with the laws of physics!
