They changed the video description!
It's no longer a copper plate, it's an enriched uranium 235 plate!
And they somehow reset the video view count and thumbs without changing the URL.
I'm no chemist, but it's a very strange material choice to demonstrate your superconductor film. And it's one of the most controlled materials on earth, so the cynic in me says it's very convenient if you don't want people to verify.
I can't help but think they are just taking the piss in response to my video.
In that case it's rather funny and I tip my tap to the joke. But when the whole world is questioning the credibility of your research, is that such a good idea?
But I'm open to someone explaining why you'd use enriched uranium 235 for such a thing?
