Invented by NASA scientists, Ferrofluid is a liquid with magnetic particles suspended in it. It’s used to help aircraft avoid radar. It can also be used for artistic purposes as demonstrated in the Hans Gretel Talking Bottle Opener video.

Ferrofluid is a fluid that contains magnetic particles that react to magnets. It’s shape changes when the magnetic field is removed and then flows back into liquid. It is made up of tiny magnet particles suspended in the form of a carrier liquid. It can be used using neodymium magnetics.

Ferrofluid is typically used by the military to cover aircraft. It can also be used in optical filters and hard drives.

Ferrofluid can be bought as either a liquid or as a bulk liquid. Ferrotec produces premium ferrofluids that can be used in vacuum rotary feedthroughs. It also is used in recycling separation processes.

Ferrofluid is used in space-related programs to assist astronauts with their critical tasks in environments with zero gravity. It’s also used in MRI equipment as well as optical filters. It is also used in speakers, actuators, and vacuum seals.

Ferrofluid is used to create sculptures by Japanese artists. These sculptures often feature black liquid that rises to form bristles that are swaying. When ferrofluid artifacts are exposed to air, the jagged edges become less apparent.

Sachiko Kodama, an Japanese artist, has created ferrofluid-based sculptures. It was used for the Montreal Science Centre’s interactive exhibit, as well as by other artists.https://www.youtube.com/embed/L8cCvAITGWM
