Ferrofluid

Ferromagnetic liquidis a liquid that strongly polarizes in the presence of a magnetic field. In other words, when an ordinary magnet approaches this liquid, it begins to create certain motions: jumps like a hedgehog, clings to a magnet, rises with a hump.
This ferromagnetic liquid is quite simple to make by hand at home.
For we need oil (motor or sunflower or other) and toner (powder) for the laser printer.
All these two ingredients must be mixed by eye to the density of sour cream.
For better effect you can shake in a water bath, stirring for 20-30 minutes.
But remember - not every printer toner is good  magnet.Accordingly,youmusttakethebest.
