Air resistance seems like a reasonable explanation for the dampening. Furthermore if it's not pure and only partially superconducting, the dampening could be due to magnetic fields forming eddy currents in the sample.

Of course.

Good hypotheses both! “We’ve never been able to pin something this size before” covers a lot of wiggle room. So to speak.

(FWIW I’m thrilled about the possibility of a rtrp drop this year, and I have to assume 'pera is as well. But this video doesn’t look just like flux pinning we’ve seen before. It’s visibly a little different in a way that wants explanation. I wouldn’t come out the gate calling it a hoax, but I’d feel better about not doing that if the basis for skepticism were at least acknowledged.)
