The liquid that is commonly used to suspend the metal is a type of oil. They use various electromagnets to create the patterns in the ferrofluid. I saw a senior design project that this guy created patterns in the ferrofluid with electromagnets that changed with the music. This uses the similar concept of the iron filings on a piece of paper and then putting a magnet underneath, except using gravity and a fluid to get a more 3 dimensional view to create the patterns

in the beggining i thought it waS mercury

hahahahaha yeah me 2.... i saw that thing in myspace and never before... but what is that thing and where can i find it?

its room temprature, its just a "liquid" with a high metal content that is warped by magnetism. its quite common, and available to buy on the web

do they have to make this very hot/melted to be like that? what is the temperature? and can you solidify this into sculptures? they would be gorgeous.. i have to read up on this a little more.. its really cool.. if someone hadn't posted this in a myspace bulletin i would have never seen or heard of this..

dis is sum awsum, trippy shit.... i mean dat in a good way

The ferrofluid follows the magnetic field lines that are made from a magnet near by. The spikes you see is the liquid following the lines, if the magnet was strong enough, or if this was done in zero gravity, the liquid would form actual lines instead of just spikes.

they could market this as the worlds most awesome 'science toy.'
