The strongest and safest magnetic construction system available! SmartMax is the magnetic discovery system that enables children, even from a very early age, to experience both the wonders of magnetism and the fascinating principles of architectural construction in a safe way. Extra-large pieces are easy for small hands to manipulate. Magnets can carry 60x their own weight, and have the ideal strength for easy assembly and break-down of constructions. Colorfully-illustrated booklets in each set present the basics of magnetic phenomena, ways to strengthen structures, steps in building towers and bridges, and construction projects from easy to advanced. Children thrive on the creative satisfaction of dreaming up their own wonderfully imaginative magnetic assemblies! Ages 3 and up.
