Intro: DIY Free Ferrofluid (low-quality)
In this instrctable I will show you how to make free low-quality ferrofluid . A ferrofluid is a liquid which becomes strongly magnetized in the presence of a magnetic field.
Step 1: Materials
What you will need :
- some rust
- a cup
- some oil
- stong magnets ( you can obtain those from a dead HDD )
Step 2: Dry Ferrofluid
Pour the rust into the cup. Crush it with a rod of metal until it turns into a dust. Now you made yourself dry ferrofluid.
Step 3: Finishing
In the cup with the rust dust put some oil until it is oil-like , but not too dense because it could not work. Now , put the magnet at the bottom of the cup (so the ferrofluid will stay at the bottom) and pour out the extra liquid.
Step 4: Last Words
THIS IS MY FIRST INSTRUCTABLE . TELL ME IF YOU LIKED IT .SORRY FOR THE FERROFLUID'S LOW QUALITY , I WILL MAKE A BATTER ONE AND MAKE ANOTHER INSTRUCTABLE.
DISCLAIMER : I MADE THIS RECIPE LAST NIGHT SO IT'S MY OWN , I DIDN'T COPIED IT FROM ANY OTHER SITE. SORRY FOR MY BAD ENGLISH :D
