The Wall Mounted Marble Roller Coaster
The 98 different track pieces stick to a wall at any angle and in any sequence with the included reusable poster putty, allowing countless configurations without marring surfaces. The 27 1/2′ of track includes fast-paced straightaways, stairs, and loops that send the 10 included marbles jumping, twisting, and ricocheting in directions and at speeds limited only by the architect’s imagination and the force of gravity. The ten included flexible tubes bend to any angle for forming hairpin turns, steep drops, or rapid declines that foster speedy descents. Price $79.95
