Description : **Not Available for Amazon Resellers** Children can build a working swing ride with this educational building set. Each package contains 486 brightly colored pieces, including variously sized connectors, and multiple styles of rods: short, long, straight and curved . Parts can be connected together to create constructions that actually move, thanks to a battery-powered motor that uses two AA batteries. This engineering set can also be used for building two other rides - a boom ride and a Ferris wheel.
