Ferrofluid is mesmerizing to behold. It has the fluid properties of a liquid and also the magnetic properties of a solid state of matter. The term itself is a portmanteau of “ferromagnetic” and “fluid.” This is because ferrofluid is made up of microscopic magnetic solids suspended in a liquid form.
Ferrofluids were originally created by NASA to better control liquids (namely rocket fuel) in zero gravity. Combined with rocket fuel, ferrofluids can be easily controlled and directed towards a pump via a magnetic field. Of course, most of us non-spacefaring humans won’t be using the stuff to power a rocket anytime soon, but luckily we can still enjoy the material’s incredible properties via a multitude of spellbinding ferrofluid gadgets.
So without further ado, here are seven of the coolest ferrofluid gizmos that money can buy.
