Using magnetic ink and any oil lying around your house, make a substance that's liquid when it's sitting around, but turn solid in the presence of a magnetic field
Step 1Intro
This instructable will show you how to make your own ferrofluid. A ferrofluid is a fluid with magnetic particles in it, and if the fluid is exposed to a magnetic field, all the magnetic particles will align with the field lines, and making the fluid much more dense. There's a lot of cool things you can do with this fluid. Enjoy!!!
- magnetic solids: come from the MICR
- surfacant : either itric acid or oleic acid (which I prefer)
- carrier: veggie oil or kerosene (which is better)
So.... for a 100ml total volume, 5ml of MICR, 10ml acid, and 85ml of kerosene.
