[sudoroom] Fwd: Ferro Fluids? (sorry bad link)

[Patrik D'haeseleer]

Just saw this project on the Make blog, about making magnetic ink - would
probably work just as well for ferrofluid:

http://openmaterials.org/2012/07/02/diy-magnetic-ink/

The page includes a link to a supplier selling magnetite powder at $16 a
pound (down to $5 a pound, for a 44lb bag):

http://shop.chemicalstore.com/navigation/detail.asp?id=FE3O4M1

I put in an order for one pound (add $9 in shipping, so $25 total -
figures...)
