Ferrofluids is an amazing liquid which reacts to the influence of a magnetic field. When a magnet is nearby the previously runny liquid suddenly starts to solidify and grow spikes that follow the pattern of the magnetic field produced by the magnet. The stronger the magnetic field the more dense and defined the spikes become.

Neato facts about ferrofluid:
It’s a portmanteau (ferromagnetic + fluid). Did you know that even though portmanteau comes from French, the French call a portmanteau a mot-valise? Trufax.
Ferrofluid is a colloidal liquid made of particles less than 10 nanometers in diameter.
When subjected to a magnetic field, the nanoparticles form regular patterns of peaks and valleys.
In electronics, ferrofluids are used to form liquid seals, like to prevent debris from getting into a hard drive.
Cancer researchers use ferrofluids in an experimental treatment called magnetic hyperthermia.
A Ferro fluid, or magnetic liquid, is a stable colloidal suspension of sub-micron sized single domain magnetic particles in a liquid carrier. The particle, which have an average size of about 100 are coated with a stabilising dispersing agent (surfactant) with prevents particle agglomeration even when a strong magnetic field gradient is applied to the Ferro fluid.
A Ferro fluid contains nearly 1017 particles per ml of liquid, making up about 5% of the total volume. Each particle in the magnetic liquid behaves like a spherical permanent magnet with a North and South Pole.
In the absence of an external magnetic field, the magnetic moments of individual particles are randomly distributed and the fluid has no net magnetisation. When a magnetic field is applied, the moments experience a torque and are aligned in the direction of the field.
