Gecko Run: Marble Run Snake 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 the snake stunt; additional marbles and nano-adhesive pads; 2 extra tracks; and more. 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! For ages 8 and up.
