A ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field making wonderful patterns. Ferrofluid was invented in 1963 by NASA's Steve Papell. Ferrofluids are used to form liquid seals around the spinning drive shafts in hard disks, but Steve Papell
invented it as a liquid rocket fuel.
But we, wannabe scientists, are really amazed by the patterns of ferrofluid, so we are presenting you the work of Japanese artist, Sachiko Kodama
Kodama was born in Kagoshima Prefecture and she is best known for her artwork using ferrofluid. She graduated in Physics at the Department of Science at Hokkaido University in 1993 then shifting her focus, entered the University of Tsukuba's Graduate School of Art and Design. After holding a Ph.D. in Art from the University of Tsukuba she has been teaching at the University of Electro-communications in Tokyo as an associate professor.

Sachiko Kodama started working in ferrofluid with her project “ Protrude, Flow” in 2000, created in collaboration with Minako Takeno. She was awarded many times for hers work.
