Move over boring marble runs, there's a new kit in town! Witness physics in action with this innovative, flexible system of tracks. Thanks to nano pads (safe little strong suction cups), any vertical surface has the ability to become a marble run. Future engineers create hills and jumps, setting up trick shots and learning through trial and error. We love that it's intuitive, mess-free, open-ended, and educational. Includes 12 tracks, 27 adapters, 40 nano-adhesive pads, 2 levers, 7 metal marbles, 4 track turns, funnel with outlet, 3 track bridges, 1 switch, and instruction booklet.
