sovenomund Music Mate Two: Colorful Ferrofluid Sound Visualizer

Ferrofluid toys are great gifts for people who love playing around with magnets. Many companies are now using this NASA engineer invented magnetic fluid to make cool sound visualizers and speakers. Take the sovenomund Music Mate Two for example: it comes with a RGB light that changes color automatically. It has a 45-degree angle, so the liquid dances better.

This ferrofluid visualizer also reacts to a handheld magnet. As the manufacturer explains, these bottles all have bubbles that prevent the glass bottle from breaking due to too much pressure. This model has automatic and sound pickup mode.
