The rock should float for a start.
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.

pardon my ignorance but why are people posting nitter links every time, what is wrong with original twitter urls?

"I’m no physicist nor chemist" means that I have no qualification to say whether the theory is legitimate or not. "It turned out that LK folks were not talking about some stupid shit" means that their theory is not out of the thin air, but rather based on some alternative theory that has not been actually disproven but simply forgotten. This one is much easier to verify. "was written and published hours before this d…
The last point doesn't make much sense since there were multiple prior similar demonstrations. It's still a prediction made after the experiment has concluded and the results are widely disseminated.

Twitter is basically broken if you don't login, compare this: https://twitter.com/andrewmccalip https://nitter.net/andrewmccalip In Twitter the latest tweet I see is from July, in Nitter is 22 minutes ago. Additionally in Twitter I get 3 notices/popups that I need to close.

I don't understand what you're not seeing. Nobody is saying that the whole LK-99 sample is superconducting. Why would you expect the whole sample to float, instead of "partial floating" as we're seeing, if you have a material that's only partially superconducting?
I was wondering this, why do all the samples not completely float. If the sample is only partially superconducting, could you just smash it into smaller pieces and find a few floating ones? Or would the different domains be so small that you have to turn the sample into dust before you get a completely superconducting piece? Probably can not be answered in general as it heavily depends on the synthesis process?

I'm guessing once they've prepared more samples and had existing samples tested they'll break some into smaller parts to try and get a piece that floats independently.

1. The synthesis process is much more complex than the original paper suggests. Every group except the original is unable to create a large piece of sufficient purity.
2. It seems like even with a pure sample, the entire structure might not be superconducting which leads it to tilt on one edge instead of completely floating. (Some call it a 1D superconductor, I’m a bit out of my depth here)
Should expect all these things to improve soon, but seems like a genuine breakthrough, not a fake or a dud’
