Go bigger with your wall-mounted marble runs using the Thames & Kosmos Gecko Run Marble Run Deluxe Starter Set! This huge 94-piece vertical marble run STEM kit has everything kids need to create high-flying tracks, loops, jumps, bounces, drops, and gravity-powered marble challenges right on smooth vertical surfaces around the house.

Flexible tracks attach with clever reusable nano-adhesive pads, allowing kids to build on doors, windows, cabinets, bookcases, and other smooth surfaces without the bulky support towers required by traditional marble runs. Tracks can be repositioned again and again as kids experiment with faster, longer, and more elaborate designs.

The Deluxe Starter Set combines the components from the original Gecko Run Starter Set with the Loop Expansion Pack and Trampoline Expansion Pack, plus an additional funnel and lever. Kids can explore approximately 20 experiments and activities while seeing concepts such as gravity, momentum, speed, energy, and engineering in action.

Perfect for kids who love marble runs, STEM toys, engineering kits, building toys, physics experiments, and open-ended construction challenges.
