As it turns out, the video is not of LK-99, and this piece does not demonstrate superconductivity. The author of the original post apologized for misleading everyone and said he regretted his actions..
It is not yet known whether the other two videos demonstrating the superconductivity of LK-99 from universities in Huazhong and Wuhan are real or not.
