These are plans for a playground or back yard Ferris wheel.
Dubbed a "Squarris Wheel" by its designer because of its square wheel, this pint-sized backyard version of its big brother, the Ferris wheel, will bring safe carnival fun right to your own home.
Braced to make it as sturdy as possible, the wheel is designed to operate on "kid power." That is, each time around, each passenger gives the wheel a backward push with his feet.
The plan's designer says there is no danger of traveling too fast for safety, and no danger of falling out of the bucket seats, since the small riders are held in by a safety bar.
Another safety feature is a set of wheel locks, which prevent the toy from being used when mom or dad can't be around to supervise getting on and getting off.
