    Gecko Run: Marble Run Rapid-Fire Launcher Expansion Pack:
    Use the Rapid-Fire Launcher to send up to five marbles onto your track in rapid succession at the push of a button! When they reach the end of the track, the marbles are collected in a magazine which can be quickly and easily reloaded into the launcher.

    Gecko Run: Marble Run Flex-Corner Expansion Pack: Tackle corners, edges, and obstacles with the Flex-Corner expansion! Quickly change direction to bend around corners of any angle or span tracks across obstructions like doorknobs or window frames. With the ability to rotate 360 degrees, this expansion adds a ton of variety to your marble run.

    Gecko Run: Marble Run Twister Expansion Pack: Give your marbles a real spin. This not only brings extra fun to your Gecko Run marble run, but also makes the laws of physics visible.

    Gecko Run: Marble Run Snake Expansion Pack:
    Send your marbles through a maze of sharp curves and see how it affects their speed. But watch out: only if you place the snake correctly in your marble run will the marbles make it through!

    Gecko Run: Marble Run Trampoline Expansion Pack:
    Get hopping! Can you position the trampoline so that the marble flies really far? Can you even bounce it downward, or catapult it up to a higher track? See the physics of projectile motion, elastic collision, and trajectory in action.

      Curiosity, Engineered

      We solve engineering problems most toy companies wouldn't attempt. GeckoBot climbs glass, Gecko Run builds marble runs on walls, and the Mega Cyborg Hand, a wearable hydraulic exoskeleton, was the #1-selling science toy in the US in 2025 (Circana).
