4. Golden Ferrofluid

Get glam with your ferrofluid and adorn your desk with this golden ferrofluid bottle. "Ferrofluid" is a portmanteau of ferromagnetic and fluid. It is made up of tiny particles, no bigger than 10 nanometres across, that will flow and spike in the presence of a magnetic field. It was first invented by NASA as a liquid rocket fuel that would still work in zero gravity. But, like so many great scientific inventions, it has now been made available to you as a wonderfully diverting toy. As well as being plain cool, these little guys are also incredibly relaxing to play with, allowing you to create a little sciencey spike-scape wherever and whenever you want.
