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.

Very cool project. There is a video of it in action[0] at the bottom. This is something that screams Kickstarter to me. [0] https://www.youtube.com/watch?v=7a3JiGTE9sc

Thank you. Video should have been embedded at the top of the website. Only a video can explain the value of the idea.

I experimented with making a clock using ferrofluid previously. I was inspired by this clock [0] but put off by the price tag. Generally the main issues I found were that it degraded over time and I had real trouble with ferrofluid smearing on the container. Will have to try again now!

That is so cool

But 12 grand!? Wow.

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

> This is called ferrofluid. It is a material developed by NASA in the 1960s. It was used as both spacecraft fuel and sealing material. I'm a bit curious how ferrofluid was used as a fuel.

It's commonly suspended in Kerosene, so maybe that's what they meant? Bit of a long stretch though.
