The Build Your Own Contraption Stunt Kit

Was $39.95 NOW $24.95

This is the configurable marble maze that enables a child to create a customized comical contraption. Providing 60 mix-and-match pieces including a chicken coop, toilet bowl, and pig-launching cannon—this whacky wall-mounted maze provides limitless layouts for hours of fun. Track clips adhere to the 2' tall backboard via hook-and-loop fasteners that support the track pieces and all its components, enabling a young architect to engineer stunts that amaze onlookers. The 100" of track pieces include fast-paced straightaways, sloped drops, and banked curves that send the four included marbles jumping, twisting, and ricocheting in directions and speeds limited only by the architect’s imagination and the force of gravity. Includes instruction booklet with tips and guides through five sample configurations. Assembly required. Ages 8 and up. 15 3/4" L x 15" W x 3" D. (3 1/4 lbs.)
