This no bearing spinner has a tension spring incorporated into the design. Wind it and let it spin!! If you time your release just right you can get some flight. The edges are made assist in winding. I included finger buttons but I found them unnecessary, but optional. It doesn't have nearly the spin bearing spinners do but its pretty fun to play with.
