[@jekyllgaming99]

I think the issue you were having with the thickness of the ferrofluid was due to the high proportion of magnetite you used - most commercially-available ferrofluids have only a little ferrous powder in the mix. Try using: - 5ml Magnetite And either; - 95ml Magnatec, or - 95ml Sunflower oil (which also contains the surfactant oleic acid, but has a lower viscosity to Magnatec).

[@zellty423]

JekyllGaming99 you're smart

[@polyjohn3425]

That's not the only issues, there's also the oil's viscosity (I think sunflower oil would work much better) and the grain size of the iron oxide. Commercial ferrofluids flow as easily as they do and form those complex shapes because the iron in them is ground into nano-scale particles with an extremely consistant grain size.

[@Alchimex_Games]

[@Crisper333]

[@yangexue6596]

So... It would be a solid magnetic block. Wouldn't that just... Work the same as a block of iron?

[@squarticus2318]

This is actually an MR fluid, ferrofluids are characterized by their ability to retain viscosity when exposed to a magnetic field (and their smaller particles)

[@dantegreenup-smith3347]

hahaha ikr

[@crusaderadonis9370]

From what I have read and heard, oleic acid is a pretty common surfactant used to make ferro-fluids. But tetramethylammonium hydroxide may work better but it's kinda unsafe due to toxic vapours and such. You could try it if you want. P.S. These are ionic surfactants so they ought to work better.

[@jpjay1584]

they do!! in Germany that´s why they invent many things.

[@draggy76]

because most kids would drink it.

[@jartef]

I mean.... These kinds of things are quite a lot more complex than what they make it out to be. Mixing oil and a magnetic substance is hardly science. When I did this in Chemistry in college, we were dealing with highly corrosive and flammable materials making it not really suitable kids in both middle and highschool. To be honest I think that most college students aren't really fit for that kind of experiments and much less interested in the theory behind it. I'm not saying that the way my college, with corrosive, mutagenic and flammable substances, did it is the only way to produce ferrofluid, but showing how to do it leaves people none the wiser as to how the world works. The theory is what is important, showing the students how it applies to reality is the experiments job.

[@blender11th]

Because showing this to 30 kids is kinda hard to do without causing mass chaos

[@Vexumy]

Because it doesn't really teach you much. Maybe viscosity and how magnets work, but nothing really scientific

[@chillaxter13]

You could try adding some dish soap to your water/magnetite mixture. Dish soap is a strong surfactant...

[@charlescooperderose8872]

Siberian Orange he didn’t use water.

[@GogiRegion]

(+Siberian Orange) That was my thought exactly. It could be a bit easier to do in a small concentration.

[@mwater_moon2865]

Nile red made a special soap (while he was making his own magnetite) and then used kerosene as a carrier for his ferrofluid. It not only worked more like the commercial stuff, it worked better than the commercial stuff, and still held together in water.

[@vadepierce1273]

You guys should try to forge a magnet

[@Ltifone2014]

Make a magnet, or heat an existing magnet?

[@jakesimm5889]

Ltifone2014 I'm guessing make. If you heat a magnet, it tends to lose its magneticness (aka magnetism).

[@vadepierce1273]

Ya make one if you melt magnets they are no longer magnetic

[@Ltifone2014]

It's super easy to make a magnet. Heat a peace of iron/steel past critical heat, and run an electric current through it until it cools.

[@noopSiesNife]

finally real ferrofluid, most people make magnetorheological fluid. Which yes, it does have the same properties with a magnet applied but its real not the same

[@Vedrajrm]

Try using a shear thinning surfactant. Those are the liquids who's viscosity reduces as you subject it to shear forces(like intense mixing) That way it can be more runny

[@charlescooperderose8872]

Why not just heat the oil up.

[@charlescooperderose8872]

Vedraj r.m so basically you’re referring to friction, when you say “like intense mixing.” Everyone knows that friction creates heat, if they dont then there’s something wrong with them, but my point being, why are you talking about shear thinning surfactants when all you would need to do is put the oil in a pot, and heat it up on the stove. Why would you possibly want to make this more hard then it needs to be? What happens to engine oil as it’s heated? It gets runny, it thins down in viscosity. The guy in this vid wanting to know how to get his oil runny is not very smart if he has to rely on us for ideas. Keep it simple for crying out loud.

[@tikkidaddy]

Drip in some WD40

[@jasonezekiel3250]

He asks us for what we want to see, plus look at the plethora of videos he has made, also I would not put motor oil next to an open flame, that's potentially a bad idea, but adding something like graphite or graphene to an oil base that is not so dense but more viscous would work. As would cutting it with detergent... You would get an amber(ish) coloured ferrofluid similar to ratsmilk (a brand of commercially available Ferrofluid)

[@xlayz3425]

Mix magnetic primer toner and some vegetable oil to get the perfect results.....

Try a different SAE rating (10w 30) etc the SAE refers to the consistency of the oil, if you’re wondering how I know this I’m a mechanic.

[@crazyaboutscience4174]

Try thin oil. Maybe cooking oil. Hopefully it works.

[@eliasandersson413]

I would guess cooking oil will act almost like the water. Motoroil are made to stick to stuff like said in the video. But maybe it will work, I don't know :)

Mineral oil is the stuff I originally had in mind before watching.

[@zickyd42]

Try synthetic valve oil for trumpets instead, it is of a much thinner consistency.

[@squishy312]

To make it more fluid and thinner, you need to sieve the magnetite so that you have ultrafine particles only. Also, use a lighter weight oil.

[@Suvrat11]

Try using different kinds of oils and even different fluids apart from motor oil and water to see if it becomes thin Maybe adding some ethanol might work If it works you can set it on fire and it will become a flaming Ferro fluid

Brake fluid is super corrosive

[@ToddRickey]

If you use a less finely powdered magnetite, it is likely that the spikes will be more pronounced. The source of such material is on most beaches in the world, which usually contain a high percentage of this oxide of iron. It is easily collected in dry sand by holding a magnet on the outside of a clear bag then placing some sand inside. Once the sand is jostled a bit such that magnetite sticks to the inside of the bag, dump the rest of the sand out. The accumulated magnetite could be collected afterward in another bag. Alternatively, use a large ring magnet to drag through the sand by a cord. Periodically, shake the white sand off before collecting the black into a bag. Finally, use a magnet to purify your final batch.

[@TheNocturnalAlchemist]

Very cool. Something I’m definitely going to try soon.

[@AbeJNacho]

[@streettruckin785]

Use a S-90 surfactant, you can find it at any agriculture store like IFA. It is a surfactant used to get herbicides to stick to plants. It sticky and clear and probably safer than motor oil to be playing with.
