Ferrofluid is a magnetic liquid, invented by a NASA engineer in the 1960s, that has, in recent years, become a popular medium among scientifically inclined artists. Ferroflow is an interactive desktop sculpture that makes it possible to play with ferrofluid—needless to say, we want it.
Nigel Stanford's song Cymatics is named for the study of visible sound vibrations, and we see sound made visible in this music video. In fact, this video is a treasure trove of science, with ferrofluid, Chladni plates, Tesla coils, and a fiery Ruben's tube.
Oh, ferrofluids, is there anything you can't do? Researchers led by MIT's Markus Zahn have devised a technique for separating oil from water. Using magnets. Tiny, tiny magnets that temporarily transform polluting oil into a magnetically manipulable ferrofluid.
Oil, watercolors and nanoscale iron particles make for some of the most psychedelic imagery this side of an LSD trip — and we've got the hi-res macro photographs to prove it.
