I would assume that certain amount of basic chemistry is still quite advanced for a non chemist.

If you would create a YouTube channel talking about basis programming language you would also attract plenty of people.

Nonetheless I don't want to lower the value or skill of him.

I'm entertained by it and can't judge his skills.

It still takes a lot to stand in front of a camera and doing what he does but still it could be that a chemist find it boring what he shows.

Young? He's 29? Were you mistaken or are you implying that 29 is pretty young to be creating self-aware youtube content.

He has videos dating 7 years back. I thought he looked young for what he was doing. Did not see him until quite a bit into the video and it was not what I expected. Really knowledgeable, a lot of equipment and a really good setup for someone so young. There is also the fact that there is no big source of income that I could easily spot.

I read it to infer that NileRed looks pretty young for his age, which I think is true.
