Build a Marble Run track that twists, turns, races and spins marbles at incredible speeds! These brightly colored chutes, tubes, drop-throughs, merry-go-rounds and spinners stack and click together to create hours of engineering fun. Toddlers simply click the pieces together to create fast and frantic runs for their marbles to roll across, shoot out and knock the dominoes down. They'll have a great time watching marbles whizz around their creations, taking bends at break-neck speed and zooming down vertical drops! Kids can even play against friends or family to see who can complete the run the fastest. Exercise your hand-eye coordination and spatial skills while putting your imagination to the test-the gravity defying feats are endless! Marble Run is a MindWare favorite among youngsters and is the perfect introduction to marble runs with pieces that go together and pull apart with ease. Multiple construction builds, entry points and supply of marbles allow for stimulating races among children.
