Thames & Kosmos Gecko Run - Marble Run Deluxe Kit, Toy Model Kit for Creative Marble Runs, STEM Toys to Foster Problem-Solving Skills, Playable Only with Starter Set, Age 8+

Innovative: Design your own vertical marble runs with this specially designed system of flexible tracks that does not require any support structures, allowing you to build higher with fewer pieces. Intuitive & Mess-free: Tracks attach to smooth surfaces with the help of clever nano-adhesive pads that create a strong but temporary bond; the pads are not glue-based and can be quickly and easily repositioned without leaving behind damage or sticky residue. Open-ended & Educational: Combine different configurations and environments for endless possibilities; develop engineering and problem-solving skills and see physics in action. Partially Sustainable: Tracks are made from renewable raw materials. What’s Included: The Deluxe Starter Set comes with over 90 pieces, including all components from the original Starter Set, the Loop Expansion Pack, the Trampoline Expansion Pack, and an additional funnel and lever component (16 tracks, 10 marbles, 56 nano-adhesive pads, and more)., Manufacturer: Thames & Kosmos
