I get that the manufacturing process doesn't produce pure samples, and that it's highly likely that the sample has many "islands" of the right lattice structure within it, of various sizes and shapes.

What I don't get is why they don't just pulverize the sample, put it in a magnetic field, and then sift out the floaty particles.

Things floating at an angle and halfway make me very suspicious.

Also, why are all these videos like 5 seconds long? The stuff is supposedly superconducting at room temperature and would supposedly float indefinitely. Why not just put up a 24/7 livestream, do stuff like pass strings/paper/loops/etc around it.

I think this material is very interesting, but all the videos I see are so clownish that I am getting more skeptical as time goes on.

it's possible pulverizing it would destroy the structure that allows this to happen in the first place
