Interesting Video??

I was scrolling around on Tik Tok and found this video. I have no clue about the authenticity of the video, but it does seem interesting in some respect.

The title of the video highlighted that the sphere was “metallic” but it doesn’t look that way to me – it looks more like a matter black colour / material.

It may not be relevant at all, but I thought I’d post it up here to see what everyone here thinks.

Also, this is my first post on this community, so forgive me for any errors.
