Gecko Run takes classic marble runs to the next level with new creative challenges and less restrictive building requirements. This innovative marble run uses a specially designed system of flexible tracks that don't require any support structures. Traditional marble runs require lots of pieces to create vertical height, but with Gecko Run, your doors, windows, cupboards, bookcases – virtually any smooth surface – become part of your track, allowing you to build higher with fewer pieces.

Attach the tracks to surfaces with the help of clever nano pads, which work like nanoscopic suction cups, to create a strong, but temporary bond. Because the pads are not glue-based, they can be quickly and easily repositioned many times without damaging adhesives or sticky residue. A quick wipe with a microfiber cloth will keep your pads ready for action!

The versatile tracks are made from renewable, durable, and sustainably sourced raw materials. Thanks to their wide range of motion and flexibility, you can create hills, jumps, and even turn corners to generate a limitless number of tricks and stunts. Each unique configuration promotes hands-on experimentation, supports problem-solving through trial-and-error, develops motor skills, and encourages creativity for kids and their grown-ups!

With the Gecko Run: Loop Expansion Pack, you can bring even more speed, action, and experimental fun to your Gecko Run marble run. How much speed does the marble need to race perfectly through the loop? Experiment and find out!

The Loop Expansion Pack comes with over a dozen pieces to complement the Gecko Run Starter Set, including a loop stunt; additional marbles and nano-adhesive pads; 2 extra tracks; and more.
