Sachiko Kodama uses ferrofluids to make amazing art.
Ferrofluids are made up of surfactant-coated magnetic nanoparticles suspended in a carrier fluid. The substance flows like a liquid and attracts to a magnet. It has a wide and increasing array of scientific and industrial applications, but Kodama is recognized for her out of the box thinking about the substance and her beautiful, sculptural art.
The Japanese artist combined her love of art and science in exploring the fascinating material and applied her training in art, design, physics, and holography to create fantastic sculptural expressions using ferrofluid.
Though the video above is a couple of years old, it is an inspiring overview of the material and the artist.
