New for 2013: Add LED light to the magnetic structures you build with SmartMax Lighthouse! 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. They magnets are strong enough to carry up to 60 times their weight! Lighthouse features 27 pieces, including 2 LED-lit magnetic bars.
