Wonder if it uses the newly developed antigravity systems......

Suprisingly simple the core technology consists of a string, a cat and a piece of buttered toast. Tying the toast butter side up on the back of the cat and then dropping both results in a perfect tension. The cat must always land on its feet and the toast must always land butter side down according to common understandings. So therefore they will spin indefinitely......

Don't believe it then try it for yourself. The materials are easily obtained ;-)
