This Ferrofluid EFH-1 was ordered a few years ago and has been sitting on a shelf.
This is one of the coolest substances you will ever play with!
Incredibly messy though.

Material used:

- 12v computer Fan Motor,

- Hard Drive Magnet,

- 2 Cylinder magnets as spin bar (I recommend purchasing one),

- Tupperware Bowl,

- Variable Power Supply*

* Can use just about any 5-12v power supply laying around - phone or razor charger,  modem or electronics PS, etc.  Just check the voltage and amperage of the motor you intend to use and compare it to the power supply. Anything over 0.5 amps likely will work.

Best to use less voltage than you motor is rated for or your spin bar may spin too fast.  Add a voltage divider potentiometer or some other means to control speed if desired.



I plan to build a self contained unit with speed control & likely hot plate in the near future. This was just a quick build because I needed one right then.



Spin bar has since arrive in the mail and I have wired the magnetic stirrer to a 5v 1amp modem power supply and it works very well.
