  • Tracks attach to the wall or another smooth surface and can be easily repositioned.
  • Kids can test out endless combinations for limitless fun.
  • See physics in action.

Gecko Run is a marble run that kids can configure (and reconfigure) right on the wall or any flat surface. It features nano-adhesive pads that can be quickly repositioned without leaving behind a residue. Kids will put their problem-solving skills to the test with this creative kit, coming up with new ways to get the marble to the bottom.

Every kid needs a marble run and this one is an affordable option that fits right on the wall. It teaches kids to problem-solve and think critically while they play. The specially designed tracks mean that kids can build it high with fewer pieces.

This is a learning tool! That means kids might literally lose their marbles, but each mistake test track is an opportunity to test problem-solving skills.

Future scientists and creative geniuses alike.


The set takes classic marble runs to the next level with creative challenges and pieces that attach to any smooth surface. Kids can create hills and jumps, and even turn corners to create tricks and stunts.
