Roller coasters are exciting and fun, complex and fascinating. They're even better when you get to construct them yourself. The Spring Bend Mini Marble Coaster brings the exhilaration of roller coasters right into your home. With 262 pieces and 6 marbles, this coaster is a complex and satisfying build, sure to provide hours of construction fun. And once the coaster is assembled, hold your breath as you watch half a dozen marbles make their harrowing trip down the hairpin turns, building speed until the winding finale. The coaster also features a battery-powered chain lift which is efficient and can serve to educate children about simple pulley machines and gears. It can also provide a hands-on demonstration of the power of momentum and centripetal force. Fun that educates without your child even realizing it! Bend the spring loaded edges to adjust the velocity and force of the coaster. The Executivity product line is made for grown-up and growing geeks alike.
