Gecko Run takes classic marble runs to another level with new creative challenges and less restrictive building requirements. This innovative track uses a specially designed flexible rail system that requires no support structures. Traditional marble runs require lots of pieces to create height, but with Gecko Run, your doors, windows, cabinets, shelves — virtually any smooth surface — become part of the track, allowing you to build higher with fewer pieces.

Affix tracks to surfaces with the help of ingenious nano-pads, which work like nanoscopic suction cups, to create a strong, yet temporary, bond. Because the pads contain no glue, they can be quickly and easily repositioned many times without damaging adhesives or leaving sticky residue. A simple wipe with a microfiber cloth will keep them ready for use!

The versatile tracks are made of sustainably sourced, durable, renewable raw materials. Thanks to their wide range of motion and flexibility, you can create hills and jumps, and even curves to generate endless tricks and stunts. No two tracks are alike! Each unique setup encourages hands-on experimentation, supports trial-and-error problem-solving, builds motor skills, and stimulates creativity for both children and adults.

With the Gecko Run: Twister expansion pack, you can put a real spin on your marbles. This not only adds extra fun to your Gecko Run marble run, but also makes the laws of physics visible.

The Twister expansion pack includes over a dozen pieces to supplement the Gecko Run starter set, including a Twister stunt; additional marbles and nanoadhesive pads; 2 additional tracks; and more.
