For anyone as fascinated with this substance as I am, here [0] is a YouTube video of someone making it 'from scratch'. It's a very detailed explanation, and includes some comparisons of the outcome VS commercial ferro fluids.

NileRed is one of my favourite chemistry YouTubers, along with NurdRage. There's so much great content on his channels.

When I first saw many of his videos, I was like: "damn, this dude has access to all sorts of chemicals, radioactive stuff, I bet he lives in Texas or Mexico".

Then I learned that he lives in the same city as me.

When I originally found his channel I thought he might be too young to take any sort of seriously, but he handles being that young pretty well. There isn’t a lot of YouTube nonsense, or begging for subscribers, or jokes that for extremely flat. A model for others I think. Really well done.

Although... Explosions and Fire is peak YouTube Chemistry to me!

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.

There's an interactive exhibit in the lobby of the New York Hall of Science that lets you deform a blob of this shiny goo. It's a lot of fun.

Thought of exactly the same exhibit -- love that thing! Worth a stop into NYHS to play with it. I immediately wanted to make one and I'm psyched to see on HN. Evidently it originally had buttons to control the charge, then curators upgraded it with the more tactile wheel controllers.

Won't the ferrofluid increase impedance and cause changed frequency response?

Great video!
