K'nex Ferris Wheel

A compact motor sends tiny seats circling around this ferris wheel, eschewing the need for manual spins or a work force of hamsters. Assembled from more than 400 parts—primarily rods and connectors—the wheel stands at more than 1.5 feet tall. Though not included with this set, the ferris wheel can be paired with the K'nex corkscrew coaster and vertical viper to create your own working amusement park.
