Gecko Run takes classic marble runs to the next level with new creative challenges and less restrictive building requirements. This innovative marble run uses a specially designed system of flexible tracks that does not require any support structures. Traditional marble runs require lots of pieces to create vertical height, but with Gecko Run, your doors, windows, cupboards, bookcases – virtually any smooth surface – become part of your track, allowing you to build higher with fewer pieces.

With the Gecko Run: Snake Expansion Pack, you can 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!  

The Snake Expansion Pack comes with over a dozen pieces to complement the Gecko Run Starter Set, including the Snake stunt; additional marbles and nano-adhesive pads; 2 extra tracks; and more.

• 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
