Ferrofluid is one of the coolest liquids around. It is infused with tiny magnetic particles that respond to changing magnetic fields to form trippy spikes and patterns. It was originally invented in the 1960s by a NASA engineer to explore the idea of moving liquid rocket fuel in zero gravity. Nowadays it is used in fancy speakers. Take the CyberPuffs Ferrofluid Speaker for instance: its magnetic fluid dances to the beat of your music.
Unlike many other ferrofluid speakers, this one has a sound pickup function, so it can react to sounds around it without a Bluetooth connection. There are various cool colors for you to choose from. A tiny magnet is included that you can use to interact with the ferrofluid inside. You can order these speakers in black or white color.
