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

If it becomes a Kickstarter, I really hope the makers know what they are getting into. There is a lot between a prototype and mass production, and a lot of projects fail between the two.

Keeping it small scale, hand made on demand and high priced may be a safer option.

Naive question: could I use a speaker setup similar to this with my analog synth rig to use combinations of sine, saw, and square waves to find combinations of waves that suspended and manipulated this ferrofluid - and would those sound shapes have applications to laser pulses manipulating atoms? Intuitively, it seems like a way to model concepts for macro quantum computer.

While atoms may not behave as liquids, laser pulses are waves. Is there specific reason why not?

Yeah, you may find that due to the mass and length scale due to the viscosity/surface tension etc. would require sub audible frequencies. Totally worth trying. As far as atomic manipulation, no since that needs to be in a hard vacuum and low temperature. The same wave interference principle is used in that technology though.

That interference principle seems like a function of the size of the blobs and then how you manage the interference patterns of multiple oscilators. Mind you, if you can physically do it with audio synths, you can model it in software, which means we should be able to use ML via a GAN to grind through oscillator patterns to create the necessary pulse effect results.

Maybe more fun for a toy or a game.

This is a great video of the effect of sound on ferrofluids: https://www.youtube.com/watch?v=Axwm-5zng0s

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. [0] https://m.youtube.com/watch?v=6L8yUY-doNc

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

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!

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.
