Build the Motorized Madness Ball Machine, a towering contraption full of building challenge and exciting performance! Towering over 4 feet high and featuring motorized lift and 3 exciting ball runs, the Motorized Madness is a builders dream. This set includes 2,004 colorful K'NEX pieces, new track system and 5 multi-colored balls. Follow the color-coded instructions to build this exciting ball machine step-by-step. Then switch the motor on to bring the model to life. The motorized ball lift continuously carries balls to the top of the tower, where they alternate down one of three different ball runs. The downward spiral sends balls down a dizzying ride to the bottom. The hammer drop transports the balls off the track and onto 2 swiveling elevators, and the funnel drop sends balls on an express ride straight to the bottom. Instructions for a smaller, alternate ball machine are available at www.knex.com. Motorized Madness is appropriate for builders ages 9 & up. Requires 2 "AA" batteries.
