This deluxe set builds working models of a house, a pyramid and various types of bridges (beam, arch, truss, cable-stayed and suspension) along with huge models of the world famous Eiffel Tower in France (59" tall) and the Sydney Harbor Bridge in Australia (56" in length)! Builders will be immersed in discovering how triangulation provides strength on a building, the main types of forces acting on structures, how trusses work, and the major types of cable bridges.
