  That one is clearly rotating. Magnetic levitation with a rotating field is not too difficult (you can get levitating flower pots as cheap novelty toys) but the sample in the new video appears fully static.

    The video in the reply (https://twitter.com/xmal/status/1300794329347260417 https://twitter.com/xmal/status/1300794329347260417) seems to show levitation even when the magnet isn't rotating?

  They're stacked to increase the field density.

  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.)
