Hubelino Marble Run - 43-Piece Switch Expansion Set - The Original!

Age Range: 4-12 Years,The switch expansion is small but powerful. By turns the marbles are directed either left or right. The switch turns itself and makes it possible to aim at two terminals at the same time. This set also includes two switches, as well as run elements, marbles, building blocks and base plates. Our robust marble runs are designed to stay put, so your kids can focus on the fun. They promote spatial intelligence and an understanding of fundamental physical concepts like acceleration and gravity.The set allows you to build a small, standalone run, complete with switches (no other sets required).Contents include: 43 pieces (22 run elements, 15 building blocks, 1 baseplates, 3 marbles and 2 switches).After each marble that passes the switch, it turns over so that the following marbles always follow a different path. So the builders themselves decide which marble reaches which target.To experience the ultimate in marble-run mayhem, we recommend using the Switch Set in addition to any of our larger marble run sets—the Mini Set is a great place to start!100% compatible with building blocks from other manufacturers. Suitable for ages 4+, but still challenging and fun for older children ages 8-12.
