This deluxe kit takes classic marble runs to the next level with creative challenges and less restrictive building requirements. What it does: 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.Attach the tracks to surfaces with the help of clever nano pads, which work like nanoscopic suction cups, to create a strong, but temporary bond. This version includes all the components from the original Starter Set, the Loop Expansion Pack, and the Trampoline Expansion Pack. In addition, it also comes with a bonus funnel and lever component.Additional features: Beause the pads are not glue-based, they can be quickly and easily repositioned many times without damaging adhesives or sticky residue. A quick wipe with a microfiber cloth will keep your pads ready for action.Includes: Plastic parks for tracks and tricks, seven nano-adhesive pade sheets; ten metal marbles and 16-page illustrated guide. Sizing information: 1.8 lb.; 14.8" x 11.6" x 2.4". Warning: Choking hazard. Small parts. Not for children under 8 years
