This 470-piece motorized, mechanical wooden work of art is a challenge to assemble, and a joy to watch as the open-air cabins rotate among intricate moving parts and gears! The ferris-wheel kit is made of high-grade laser-cut plywood that requires no glue or tools to assemble. The mechanisms are all exposed to show the movement and there is a hidden compartment on the bottom. Includes easy, step-by-step instructions. Assembled size is approx. 8 1/2"L x 10"W x 12 1/2"H.
