Adahill Hoptech Bottle Ferrofluid Magnetic Liquid Display Toy

Product Information

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."

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 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. 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.

After he completed his initial prototype, Jung decided to share his speaker with the world. This, in turn, inspired his possible future plans to bring it to market. “I started making it for fun, but after posting it on my social media, [people were telling me to] ‘shut up and take my money,’” he said. 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

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!

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.

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. Before anyone suggest to buy online, I would like to make it myself and learn the whole process VS store bought item. You can make brakes with it by putting some fluid between a wheel's axle and hub. The wheel will spin freely as the fluid acts just as a liquid lubricant, but if you apply a magnetic field, you're suddenly putting a lot of friction of the wheel's rotation. 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 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.”

No biggie. For aqueous ferrofluid, silanize the glass with Rain-X automotive windshield treatment. If you want both a hydrophobic and oleophobic glass surface, fluoroalkylsilane surface coupling I absolutely love this lamp...it makes quite a pair with my ORIGINAL Lava Lamp (1960's model). Only negative is that once you 'become one' with the ferrofluid you're hooked. Two thumbs up for this."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.
