With the Gecko Run: Loop Expansion Pack, you can bring even more speed, action, and experimental fun to your Gecko Run marble run. How much speed does the marble need to race perfectly through the loop? Experiment and find out!

The Loop Expansion Pack comes with over a dozen pieces to complement the Gecko Run Starter Set, including a loop 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
• Partially Sustainable: Tracks made from renewable raw materials
