A strange exposition video then, I would try to remove the part that wasn’t superconducting (the part touching the magnet) before I released this. A completely floating piece of this superconductor would remove literally all doubt.
Scope of the claim. This is world changing. Shoot the first video, then get the dremel/pliers and cut that large bit off. It would be worth it, because if this works at all, then it's vital to prove it. We'd be having a very different discussion if that small piece was umabiguously floating and remaining locked in place.
For one thing, because if you're throwing out a world-changing claim, you yourself would like to be sure it is what you think it is.
It's an obvious test to do, so it's quite surprising they didn't do it. Maybe they did and didn't film it, I don't know - but for the trouble of a couple of minutes of time, it's weird not to have it - especially if your method is reproducible.
