Quercetti Skyrail Rollercoaster with Elevator, 200 Pieces
With 60 years of experience creating educational toys, Quercetti has contributed to generations of children engaging in beneficial play that encourages creativity and stimulates intuitive reasoning. The 200 piece Skyrail Rollercoaster with Elevator is a wonderful marble run building set. Construct a suspension system, and then send marbles racing around the course. It takes just the right amount of tension to race all the way to the bottom without falling off or rolling back. As marbles reach the bottom of the coaster, the battery-operated elevator lifts them to the top in an endless stream of gravity-powered excitement. Includes 15 feet of glow-in-the-dark track, 4 marbles and a detailed instruction booklet. Perfect for demonstrating gravity, speed, inertia, centrifugal force and other principles of mechanics and physics. Compact size is great for table tops. Made in Italy. Ages 8+.
