Ferrofluid - a magnetic liquid developed by NASA and sitting on top of a magnet following the lines of the magnetic field.
Laowa 25mm f/2.8 2.5-5X Ultra Macro
This image shows a ferrofluid - a liquid that is magnetic. It consists of nanometer-sized maghemite particles dispersed in a liquid. Maghemite is γ-Fe2O3, a kind of rust.
The maghemite is put on a watch glass, with a magnet placed under it. The so-called spikes point in the direction of the magnetic field of the magnet.
My homebrew ferrofluid.
It is a mixture of printer toner (which contains magnetite nanoparticles) mixed with plain olive oil, suspended in distilled water.
The mixing ratio is about two or three parts toner to one part oil.
The black blob can be manipulated with strong magnets, but I still haven't seen the typical spikes.
The toner was harvested from an OKI G282-23 toner cartridge (p/n 09004391).
I will continue to experiment with other suspension fluids and mixing ratios.
Please be extremely careful when trying this.

As the magnet pulls away from the fluid it forms peaks, as it moves back towards the fluid it collapses again.
I want to try some other ideas with ferrofluid but this was a quick test to see if it looked promising. The silver thing is a rather large (finger crushing) rare earth magnet (about 4cm diameter). The ferrofluid is just dripped onto the magnet with a petri dish to keep the ferrofluid off the magnet.
Ferrofluid is a pain to play with. It is as bad as the Cat in the Hat Comes Back, staining everything that it comes in contact with.
Cheers.
Trying out my new Nikon 60mm macro lens. The depth of field is much more manageable than my home-brew reversal macro lens. This should give me more flexiblity and control when composing shots.
Did a final day of testing to find an ideal bubble mixture liquid medium which would stand up to the ferrofluid being drawn through the capillaries.

Some photos are ferrofluid alone. Some are ferrofluid + watercolors. Some are ferrofluid + cornstarch/water.

A little macro fun with ferrofluid and a magnet. I found a stronger magnet today so hopefully I'll have some more interesting shots with this wonderful liquid later!

Here is a cool YouTube demonstration of ferrofluid... www.youtube.com/watch?v=fAbycqD2UmQ&feature=related
And here is the Wikipedia article on it.

Nothing to do with gravity, high-speed, flash or anything like that... all to do with a magnetic personality.
ok, it's ferro fluid. This stuff is trickier to work with than I had originally given it credit for. And it seems my A' level in physics is a load of pants as well... Why didn't I pay attention when we were doing "flux density"!!!!!

ferrofluid close-up. A ferrofluid (portmanteau of ferromagnetic, and fluid) is a liquid which becomes strongly magnetized in the presence of a magnetic field. Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water).
