Ferrofluid
Have you heard of ferrofluid? Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water), and they become strongly magnetized in the presence of a magnetic field.

There's loads of videos of these on YouTube, but I like this one in particular. Fascinating stuff.
