Winner of a Parents’ Choice Gold Award, this is the 323 piece building set that lets children construct miniature bridges and skyscrapers. It provides young engineers with interlocking modular pieces that snap together to form 20 different models inspired by real architectural marvels such as the Golden Gate Bridge, Brooklyn Bridge, or Empire State Building. Each bridge or skyscraper demonstrates principles of mechanical physics such as force, tension, and compression and illustrates basic structural elements such as columns, beams, trusses, and archways. The set includes a 44-page full-colored instruction booklet. Ages 8 and up.
