Ferrofluid

Viewing domes remain crystal clear because messy ferrofluid splash droplets never touch the domes .

Ferrofluid Experiment

Bolt on a strong magnet with ferrofluid on the bolt.

Ferrofluid is a really cool liquid. It has tiny magnetic particles suspended in it so that it reacts to magnets. No magnetic field; it's just a liquid. Apply a magnetic field and suddenly the liquid develops peaks and valleys. The stronger the magnetic field, and the further away the magnet is held (subject to the strength of the magnet) the bigger the peaks. Cool huh? More info here: en.wikipedia.org/wiki/Ferrofluid

A closeup of ferrofluid under the influence of a large donut magnet; shot through a 100mm macro lens. This was taken during the shooting of a friend's video project, an art piece involving objects under the influence of magnets.

Stacked versions of my ferrofluid shots, gives a greater DOF
