Quick and dirty ferrofluid

When we posted our first ferrofluid story [frogz] threatened to make a video of his own version. Well he did and here’s the video. He uses laser printer toner and suspends it in lightweight SAE10 motor oil. He says that a thinner oil produces shapes quicker. I don’t think the power drill with the spoon attachment is really necessary though.

  1. Hey guys, I am trying to do this experiment and I was wondering if HP Toner Refill for laserjet cartridge would work for the ferrofluid? Especially the guy who worked on printers for more than 10 years please comment on this. Thanks.
