|This is a unique construction set based on a very simple concept: magnetism. The Geomag building system has the polarity and magnetic strength to create geometric shapes and structures. It consists of plastic coated rods with a south-polarized magnet at one end and a north polarized magnetic on the other end. Build a radar receiver, a UFO, two-dimensional shapes (triangles, pentagons and octagons) or more complex three-dimensional models (cubes, pyramids, stars and spheres). The possibilities are limited only by your imagination! This 96-piece set will allow children 8 years and older to create larger and more complex structures. Includes 60 rods and 36 spheres and is available in mixed color sets of yellow and red. Geomag is manufactured in Switzerland.
