Ferrofluid is a special kind of liquid that’s attracted to magnetic poles. DAKD Jung shows off an awesome custom-built speaker that takes advantage of this property to propel and direct ferrofluid to the beat of the music. A second video shows off how it works. It’s basically the Lava Lamp 2.0… and we want one.
Designers Graham Plumb and Stephen Braitsch collaborated on this amazing mechanical display that uses a series of 180 magnets to write text in a pool of ferrofluid. They built 10 custom machines which are programmed to raise and lower magnets, creating the segmented letters in the oily fluid.
