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

Attach the tracks to surfaces with the help of ingenious nano pads, which work like nanoscopic suction cups, to create a strong, albeit temporary, bond. Since the pads are glue-free, they can be quickly and easily repositioned many times without damaging adhesives or leaving sticky residue. A simple wipe with a micro-fiber cloth will keep them ready for use!

The versatile tracks are made of renewable, durable, and sustainably sourced 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 configuration encourages hands-on experimentation, supports trial-and-error problem-solving, develops motor skills, and stimulates creativity in both children and adults.

With the  Gecko Run: Loop expansion pack, you can add even more speed, action, and experimental fun to your Gecko Run marble run. How much speed does the marble need to complete the loop perfectly? Experiment and find out!

The Loop expansion pack includes over a dozen pieces to complement the Gecko Run starter set, including a looping stunt track; additional marbles and nano-adhesive pads; 2 additional tracks; and more.
