How to make DIY Ferrofluid displays | No staining!

[@max_mittler]

Am I the only one who thought it was crazy when he rinsed it with tap water after spending all that time decontaminating it?

[@kinbolluck476]

Hydrocarbon contamination is goal

[@PuissantAlgernon]

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.

[@Blackbird58]

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!

[@ГрэдиОДоэрти]

Great video, thank you. It really helped to comprehend all this stuff with polar and non-polar liquids and molecules

[@georggrieger2988]

really well done video! shame it doesn't have more views :(

[@davegoulden9521]

Density. Fantastic video. My lava lamp idea will work

[@pinkymacgyver8773]

Dude, where can we see your lava lamp?

[@MakeTeachRepeat]

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.

[@whatelseison8970]

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!

[@lung0fish1]

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.

[@dominicperkins4335]

I know you posted this video a while back (so I'm not expecting an answer), but do you think sterile (until you put stuff in) lab vials that you fill with syringes would work without all of the prep work? Edit: It doesn't work lol

[@pinkymacgyver8773]

Thanks for the edit on this haha 👍

[@JourneyCamera]

deserve recognition.

[@peterthornton6145]

Cool project. Interesting that you can just rinse with tap water after the cleaning.

[@satankidd9687]

My thoughts also why take all that time and effort to then just rinse it all off with something loaded with impurities

[@gevinblue]

thank you! My ferrofluid display made of 70% hydrogen peroxide and 30% water (91% distilled) made the ferrofluid stick to the glass on the sides and bottom. I’m yet to try this out but i am excited to as i have almost everything.

[@gevinblue]

didn’t work

[@jakegoat2677]

@@gevinblue Thanks for letting us know, you just followed what he did in the video exactly?

[@gevinblue]

@@jakegoat2677 well I did the same things but I probably done it wrong bc it’s literally the same thickness as peanut butter 😭👍

[@owlredshift]

That narrator is totally the unaltered voice of Nerd Rage. I've always wondered what it sounded like, this is 100% him.

[@laconic6077]

"To explain that, I have made these cute little nano particles." Me: 😲🥺 awe. ♡

[@Stevobulfer]

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

[@liltofu9480]

Love the dedication

[@miguellopezlloret9853]

Amazing info, thanks for your work!

[@undocked9647]

this is the exact kind of thing i was looking for omg

[@kathyhayes-bromley5199]

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]

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.

[@Chriss2370]

Yes, yes very well done indeed. Very emotional!

[@anhtruong6908]

The ferrofluid from the second seller is actually just a repackaged of Ferrotec's ferrofluid. So the quality should be the same with the grade being EH1.

[@SolHuebner]

Thanks for the detailed video :)

[@ZappyOh]

Someone please invent Ferro-Smoke ... a magnetic visible gas.

[@henryoppenheimer]

That's such a good idea.

[@comedyianca]

this is so helpful!

[@coatduck]

This video is terrific, but I noticed that your video was exported with interlacing, which is causing little horizontal lines near the edges of movement.

[@robindebreuil]

This is fantastic information, thanks!

[@aaronharris8245]

Thank you for your video appreciate it.

[@Blackbird58]

Wasn't it worth considering using some jewellers gem polishing paste on the inside of the glass jars?

[@devrim-oguz]

As soon as I saw the staining, I thought about plasma cleaning the glass without you mentioning the surface. Maybe this could help.

[@janneliimatainen6186]

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.

[@dreadin]

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.

[@georgenaylor1894]

Another way is saturated sugar solution in a glass cleaned with caustic soda and rinsed clean.

[@ukskatescott]

If you keep getting the weird lines on export of your videos, try export in 1080p not 1080i

[@manjichromagnon5480]

My guess is that the salt simply increases the buoyency of the ferrofluid

[@pablorios081]

Gran video, método en general complicado

[@ORBITALAURORA]

Awesome 👍🏻 Did you consider 70% alcohol. Will be making something cool so will need to try a few solutions 👉🏻👍🏻👍🏻👍🏻

[@canebrakeruffian1122]

Did the alcohol work?

[@pinkymacgyver8773]

Also interested in your experiments 😊

[@MyAmbianceLiveNow]

Thank you! 🙌🏽🙌🏽🙌🏽🙌🏽🙌🏽🙌🏽🙌🏽

[@Ogbrainded]

Cool video but I wish he will show us the link where he bought the ferrofluid

[@EricThornton24]

Hey Brainded, links to products can be a bit tricky as they often change or go dark... But as of right now (5/25/2021) the fluid I used in this video can be bought on amazon at amzn.com/B00126LYAG. Hope that helps, and thanks for watching! -Eric

[@Ogbrainded]

@@EricThornton24 thanks

[@MyAmbianceLiveNow]

Make sure not to heat the fluid too much once it’s bubbling it’s good because it will burn and evaporate otherwise lol

[@meMe-ke4kz]

In 8:58 it says that the cap should be closed but it is capped…can anyone explain?

[@emicadavis1440]

I need s written step by step lol

[@otiswong2091]

nice

[@lung0fish1]

Hunh. Sodium carbonate+hydrogen peroxide is similar to something called "base piranha" that etches glass.

[@lung0fish1]

Silanization might also work....

[@diegobotina8782]

Good night. Can you kindly sell me ready-to-use ferro-fluid. I have not been able to with everything that explains. Thank you for your attention.

[@eventhorizon444]

The salt might be something to do with buoyancy?

[@frankieslattery615]

Ferrofluid diy

[@mikaelbjornson2666]

Hot, concentrated sodium hydroxide solution followed by a rinse in deionized water would be the simpler solution.

[@ferrofluiddisplay8107]
