Gecko Run: Marble Run Twister Expansion Pack

Gecko Run takes classic marble runs to the next level. Attach the tracks to vertical surfaces with the help of clever nano pads, which work like nanoscopic suction cups, to create a strong, but temporary bond. Designed for use with the Starter Set (sold separately), this expansion pack comes with over a dozen pieces, including a twister stunt; additional marbles and nano-adhesive pads; 2 extra tracks; and more. The twister will give your marbles a real spin, bringing extra fun to your marble run while allowing you to see the laws of physics in real time. For ages 8 and up.
