This is an hoax and it's sad to see people like Sabine Hossenfelder falling for it so easily:

- video recorder in a kitchen or living room

- created by some random tiktok account

- no credentials, no description

- tagged "mysterious"

It's hard to understand how anyone would believe this, specially after so many other fakes

[p-o]

Hoax is quite a strong word where there's been quite a few replication attempts with various degrees of success. Like others have said, we're not sure what this is, but it almost certainly isn't a hoax.

As for this video, well, it's like all the other ones that came before it, we'll know more once we have more data/videos/replication attempts.

I meant that this video is a hoax. I don't hold any opinions regarding LK-99.

Some of the other videos were at least from some more or less reputable sources. This one appears to be anonymous, or am I wrong?

The source[0] seems to be the Douyin (TikTok) user 炼丹师阿翔[1], who also posted a different LK-99 demonstration video[2] a few days ago that shows similar results to previous demonstrations by other researchers.

Yes but what research institute are they affiliated with? For all I know this is an pseudonymous TikTok user who is good at faking videos. Why should I take this for anything but complete fiction?

[Hakkin]

Certainly not making any claims of the legitimacy, just providing the original sources. There doesn't seem to be any attribution besides the anonymous account.

The Chinese subtitles in the first demonstration claim "further efforts will be made to reduce impurities", then the subsequent video claims "technical details will be published once they are properly organized and documented".

I see no indication that it was filmed in a kitchen or living room.

In fact I see some serious lab quality glassware in the background. But posting without its provenance is a weird for sure.

IMO there’s an awful lot of amateur / informal attempts that are promising enough that, while not convincing, are inspiring of hope. But I do wonder how much is fake. But more than a few seem to be clearly not fake, such as the work Varda is posting.
