Have fun building incredible structures and vehicles with SmartMax! SmartMax allows children to explore magnetism safely. 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 towers, bridges and other creations. The magnets are strong enough to carry up to 60 times their weight! The Basic Stunt set is a great combination of SmartMax fun: building both structures and vehicles. Includes 46 pieces and a guide to build models.
