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. This is just about the simplest ferrofluid you can make. You'll need two basic materials: magnetic (MICR) ink, and a household oil. I've tried a couple types of oils, and it seemd like a light lubricating oil works best, but any cooking oil will work fine, as well. The amount of oil you have is pretty much the amount of ferrofluid you'll get out--about 50mL is good for starters, but feel free to make as much as you want.

As a result, he’s now considering ways to develop the concept further, with an eye on eventually manufacturing a model he can sell. “We are trying to combine with various speaker types,” Jung explained. “We plan to create a device that can be used by connecting to a high-fidelity speaker rather than a Bluetooth speaker.” As the latest generation of Earfun's Free Pro model, the Free Pro 3 goes all-in on new features while retaining the ultra-compact shape and style that sets the Free Pro apart from larger earbuds. The headlining feature for some Android users is Qualcomm's Snapdragon Sound compatibility, which brings hi-res audio support via the aptX Adaptive Bluetooth codec and higher-quality voice transmission thanks to aptX Voice.Ships in 2 business days Patented Technology This is an actual lava lamp with NASA derived nanotechnology inside. The 'lava' is made of a magnetic fluid called ferrofluid. Like an ordinary...

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. 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.

Very cool lamp! Great conversation piece. People play with it for hours on end. Size is better (larger) compared to other like items. This is about the same size as a normal lava lamp."

You may have heard about harvesting iron oxide from cassette tapes using acetone. If you’d like to try this method, break apart cassette tapes and soak the tape in acetone for 1 hour outside. Then, use a knife to gently scrape the iron oxide off the tape into a dish. Just keep in mind that many people have tried this method with little success, so it’s a better idea just to buy iron oxide outright. Now add double the volume of Acetone to extract these particle out of the solution. They stay coated with Oleic acid.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 Since finding out about ferrofluid, Jung has used it in multiple pieces of art — including an impressive ferrofluid “ Pataphysical Pond,” in which the ferrofluid spreads out like a live oil spill or an ever-shifting Rorschach test. The idea for the speaker came to him when he was listening to music while playing with a ferrofluid display cell he had built. Absentmindedly, he manually began timing the electromagnetic pulses to match the music he was hearing. Ships 8/12/19 This Does NOT act as a lava lamp. Instead, it has magnets at the bottom of the bottle to keep the ferrofluid spiky at all times. The ferrofluid comes... Whatever form it ultimately takes, who wouldn’t want one of these? This is pretty much the definition of a party piece in every sense of the word.
