Adahill Hoptech Bottle Ferrofluid Magnetic Liquid Display Toy

Product Information

This was the purification process. Note that you can also use paint thinner in place of petrol and isopropyl alcohol in place of Acetone. When the iron oxide mixes with the oil, the iron particles stay suspended in the fluid rather than mixing entirely. When you introduce a magnet to the ferrofluid, the magnet pulls the particles apart, forcing the fluid into interesting shapes, peaks, and valleys. Laserprinter toner isn't usually a mix of suspended magnetic particles: only specialty toner inks are (the ones used for machine readable printing). If you can get the right sort, it will save a lot of effort, but the wrong toner won't work at all and will just make a mess.

The good folks at the Univeristat Der Kunste Berlin made a ferrofluid display that can play Nibbles: http://www.digital.udk-berlin.de/en/projects/winter0405/main/hauptprojekt/snoil.html A solution of ~25% distilled water (a.k.a. deionized water) and ~75% of store bought isopropyl alcohol at 91% concentration. That means that ~70% of my solution was actually isopropyl alcohol. I eyeballed the ratio between the water and the isopropyl alcohol, those numbers are likely to not be exactly correct. The Fidget Tornado | 3D Printed Fidget Cloud | Sensory | ASMR | Tinker Tool | Stress Relieve Desk Toyheat the solution to about 80 ℃ – 90 ℃ . The ammonium oleate will decompose to again form oleic acid (which is hydrophobic) and it will separate out the magnetic particles from the solution. Add some isopropyl alcohol to the glass container. Then add some (or all) of your ferrofluid to the container. Then add some water to bring your isopropyl alcohol concentration to about 70%. Next, use a magnet to settle the ferrofluid to the bottom and then remove the magnet. If your ferrofluid has little bits that are floating, then you need to add more water. If your ferrofluid looks too stringy then I would add more alcohol. When I was done the ferrofluid had zero staining, like you see in the videos online, except for in a few spots. I think for better results I would need a higher quality glass container. Use a magnet to manipulate the ferrofluid. Since iron oxide is magnetic, it will automatically gravitate toward the force of a magnet. Place your magnet underneath the petri dish and move it around. Have fun playing with your ferrofluid! [4] X Research source Dissolve the soap in water with some acid (sulphuric). The oily substance collected at the top is mostly Oleic acid with stearic acid and linoleic acid. This can be further purified by refrigeration. Iron oxide powder creates the magnetism in ferrofluid. Use your electronic scale again to measure your iron oxide. Then, pour the iron oxide into the motor oil. [2] X Research source

Dissolve the Oleic acid coated particles in petrol/kerosene and then keep the beaker over a big magnet to precipitate the unwanted big particles. Then Decant the useful Oleic acid coated particles which stayed in the solution For rare earth magnets cheap, hit up a two way radio shop. I'm constantly replacing speakers in portables (uh, walkie-talkies to those not in the industry). The, more or less, dime sized neo magnets are what I use to hold a lot of tools suspended from the four foot fluorescent light over my repair bench. Drivers, wrenches, a hammer... They're small but powerful. Now let the particles dry out and then add a few drops of kerosene/petrol to make a concentrated solution. The ferrofluid should be ready now.Glass bottle, ideally with flat sides. If you have a round bottle you may not be able to see the ferrofluid due to diffraction.

Motor oil is the carrier oil that will hold your fluid together. Measure out the motor oil using an electronic scale. Then, pour the oil into a shallow dish made of thin plastic, like a petri dish.

Now add double the volume of Acetone to extract these particle out of the solution. They stay coated with Oleic acid.
