Thames & Kosmos Gecko Run STEM Marble Run Starter Set for Ages 8+

The Gecko Run Starter Set breaks free from traditional marble run design by using nano-adhesive pads that stick tracks directly to walls, windows, furniture, and almost any smooth vertical surface. Kids build gravity-defying courses that climb bookcases, zigzag across cupboards, and race marbles through the air without bulky frames or support towers. The nano pads (which work like microscopic suction cups) hold strong but peel off clean without residue, and a quick wipe with the included microfiber cloth refreshes them for the next build. This starter set gives builders in grades 3 through 8 everything they need to experiment with angles, momentum, and physics while creating completely custom racecourses limited only by the smooth surfaces around them.

• Builds critical thinking and engineering skills as kids test different track configurations, adjust angles, and problem-solve to keep marbles moving through their courses
• Nano-adhesive pads attach and reattach to smooth surfaces hundreds of times without leaving marks, damage, or sticky residue
• Flexible track pieces bend and pivot to create hills, curves, and jumps that traditional rigid marble runs can't achieve
• Grows with builders from simple straight runs to complex multi-level designs that demonstrate real physics principles in action
• Microfiber cleaning cloth included to keep nano pads working at full strength
