Adahill Hoptech Bottle Ferrofluid Magnetic Liquid Display Toy

Product Information

To the solution add small amount of Oleic acid and some excess of ammonia which will form ammonium oleate which binds to the magnetic particles and is soluble 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.

It is then possible to make the glass surface superhydrophilic through a special coating. In addition, ferrofluid must be made not to oxidize for a long time because the main ingredient is oil.” 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. [1] X Research source Glass bottle, ideally with flat sides. If you have a round bottle you may not be able to see the ferrofluid due to diffraction. Now add double the volume of Acetone to extract these particle out of the solution. They stay coated with Oleic acid.

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." A network music streamer is an internet-connected hardware component that streams your favorite digital music using an internet connection. A good network music streamer is easy to use, compatible with several file formats and music streaming services, and will ensure your digital music sounds good to appease both casual listeners and esteemed decibel sages. CDs and vinyl records are two physical audio formats that some folks swear by, especially when it comes to sound quality. But even the most tenacious audiophiles have come around to the excellent sound quality now available on digital streaming services, so much so that digital audio has become the primary way we consume our music. But with the range of hi-fi setups people have at home, new and old, one of the best ways to bring your digital audio and online streaming services to them is by adding a dedicated network music streamer.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!

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.

Like an ordinary...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. I'm building on-the-fly braille translators and tactile interfaces by sensing if people are moving the fluid: http://www.artiswrong.com/ffb

I don't have a full answer, but a hint at how to choose your liquid. You want the ferrofluid not to mix with it, so your fluid has to be immiscible with the ferrofluid solvent (or carrier fluid; ferrofluids are colloidal suspensions). In the case of your “FerroFluid EFH-1”, the solvent is a light mineral oil, so you should go with a polar solvent. 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. 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. Dispose of ferrofluid like you’d dispose of motor oil. Since ferrofluid is mostly motor oil, it’s considered hazardous waste. For small quantities (like 1 batch), seal it in an airtight container and throw it in the trash. For large quantities (like multiple batches), take the ferrofluid to a hazardous waste facility.
