    Gecko Run: Marble Run STEM Edition

    Build and experiment with physics using vertical nano-adhesive marble tracks.

    $39.95

    Bring physics learning to new heights with Gecko Run. This innovative take on a classic marble run is highly dynamic and engrossing. Tinker with the flexible track system, loop-de-loop, and other tricks to create your perfect run. Traditional marble runs require lots of pieces to create vertical height, but with Gecko Run, your whiteboards, cabinets, doors, windows, cupboards, bookcases – virtually any smooth surface – become part of your track, allowing you to build higher with fewer pieces.
    This hands-on kit provides the perfect opportunity to experiment with physics and learn about potential and kinetic energy, angle of incline and velocity, collisions, momentum, centripetal force, elastic potential energy, conservation of energy, and circular motion.
    Attach the tracks to surfaces with the help of clever nano-adhesive 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 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!
    The Gecko Run STEM Educational Kit includes everything you need to zip, zag, bounce, skip, and hurdle into an awesome engineering adventure. A 16-page illustrated manual guides you through setting up your first runs and teaches you how all the different elements work. Witness physics in action! Use independently or combine with any of the expansion packs.

    • Intuitive: Tracks attach to smooth surfaces with the help of clever nano-adhesive pads that stick to smooth, vertical surfaces around your home
    • Mess-free: The pads are not glue-based and can be quickly and easily repositioned without leaving behind damage or sticky residue.
    • Open-Ended: Position in endless configurations on smooth surfaces
    • Educational: Develop engineering and problem-solving skills, and see physics in action
    • Challenges: The open-ended challenges set rules such as using only the specified parts in an allotted amount of time to achieve a stated goal, like the longest run or the fastest run. There are many possible solutions to each challenge, making them excellent for hands-on engineering design activities.
    • Tracks made from renewable raw materials
    • Additional stunts available in expansion packs sold separately)
