Kinetic rotational body of coiled flat, round, polygonal or tubular material - has vertical axles, in form of ring or flat or three dimensional figure, and is set in middle of torus shaped body

摘要

The material is coiled to form a torus shaped body (1) which rotates on a mainly vertical axis (2) positioned in the middle of the rotational body under the effect of its own weight. The axis is an enclosed circular ring or other flat or three dimensional figure. The axle's surface is dulled and possesses sufficient static friction so as not to slip. The cross section of the coils is non circular, and the coils of the rotational body are in one or more colours. ADVANTAGE - The rotational body is for demonstration or play, to attract attention.
