The rock should float for a start.

Meissner Effect does not mean it has to float. It only floats if thats the easiest way to expulse the magnet field. Otherwise it aligns normally with the magnetic field, which is supposedly happening here.

As it’s been theorized elsewhere, it may be that the production processes produce a material with only bits of the theorized superconductor in it, leading to the wiggling effect we see here as well as the Chinese replication video.

It is not a purity issue. On the other hand, 1D superconductors are expected to behave this way. See my other comments.

How do we know it isn't a purity issue?
