Plate spinning. Plate spinning is a circus manipulation art where a person spins plates, bowls and other flat objects on poles, without them falling off. Plate spinning relies on the gyroscopic effect, in the same way a top stays upright while spinning. Spinning plates are sometimes gimmicked, to help keep the plates on the poles. Many Chinese acrobatics troupes feature plate spinning, usually in combination with contortion or acrobatic skills.
