Build a Playground of tubes and tracks that you can run balls through with this new SMARTMAX set. Create the wildest structures and let the balls roll! SmartMax allows children to explore magnetism safely while developing STEM skills. The oversized pieces are specifically designed for handling by young kids as they learn about the effects of magnetic attraction and repulsion, while older children will have fun using the pieces to construct ball runs, towers, bridges and other creations. All parts can be combined with all existing SMARTMAX sets, creating an endless range of possibilities.
