Gecko Run takes classic marble runs to the next level with new creative challenges and less restrictive building requirements. 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. Thanks to their wide range of motion and flexibility, you can create hills and jumps, and even turn corners to generate a limitless number of tricks and stunts. No two tracks are ever the same. 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.
