Really interesting. I'm hoping to use some ferrofluid in a display at an immersive experience I'm building, and it was great to finally find some tips on reducing staining.

Apart from the fact that it's probably lethally toxic and would also stain the skin a darker shade of charcoal, if there was enough of it to fill a pool, it would be really cool to swim in that stuff!

Salt makes the glass surface more polar by induction on contact with water. It increases the separation of polar and non-polar substances - used to do thuisbioscoopsysteem the lab to separate emulsions and extractions.
@whatelseison89703 жыл бұрын
If you brought the water in the vial to a boil and then rapidly sealed the lid then oxygen could be largely excluded while leaving room for expansion. The pressure inside would simply end up being the vapor pressure of water at the ambient temperature (assuming the V.P of the non-polar solvent is negligible by comparison). Alternately you could add a nitrogen atmosphere to prevent oxidation. I'm no expert on ferrofluids or.. cleaning for that matter but that's a bit of a random sample of my thoughts on the video. Cool stuff though. Keep making vids and crackin' wise. I can't wait to see the follow up to the laser project. Part 1 is great, I can't wait for the second installment of it not working. Now quit lazing around and get to _lasing_ around!

I thought that this would be a literal display, like a sort of electronic ink pixel thing (idea for future?). Good work figuring out the nonsticky bit.

Salt works because it makes the water more polar, causing it to stick more to itself than non-polar ferrofluid

Can you make this in a bigger jar? Also what is needed to make the ferrofluid react to music? I know magnets are involved, however, where are they placed?
@Hellsong89 Жыл бұрын
Oxidation probably happens due lid leaking some air in or/and air in the container causes the oxidation. One way could be to put some inert gas like argon into container and making best possible seal to lid so no oxygen can get in.

@janneliimatainen61863 жыл бұрын
have you ever tested piranha solution (sulphuric acid + hydrogen peroxide) for cleaning the glass? I´d guess you won´t need a strong solution of it because the amount of contaminants are very low.
@dreadin3 жыл бұрын
Try using a solution named Hellmanex III (vendor e.g. Sigma Aldrich) for cleaning the glass instead, it would be a lot less work and should yield the same result.
