The object that is rotating is a magnet. It's not what we're seeing with the flake which appears to be flux pinned.

If this is fake, it's a very well-done fake. I'm feeling 60% sure that LK-99 is RT superconductor at this point. It has theoretical support now since last weekend.

Most flux pinning examples on youtube allow rotation (With round superconductors and magnets, though.)
