Even if it doesn’t turn out to be a superconductor, it is at least strongly diamagnetic, so it opens avenues for future research either way. There’s a potential scenario here where this doesn’t turn out to be a superconductor, but it nonetheless leads to a superconductor further down the line.
The one wrinkle here is if the sample we saw actually was pyrolytic carbon and someone simply mislabeled a vial when looking for something to shoot the video with.
At the extreme end of big news, stupid things can happen (I've worked in a lab: people suck at labelling things they make).
If it is pyrolytic carbon, they've somehow significantly enhanced the dimagnetism of it, which is remarkable. Usually that stuff only barely floats, and only when it is very thin.
