Glass sphere where black liquid climbs and falls with the beat

Inside the sphere is ferrofluid, a black liquid that responds to magnetic fields. Feed it sound and it spikes, drops, and ripples in time with the track. The base lights up while it plays.

Why choose this desk sculpture?

Quiet tracks and loud ones produce different shapes, so it never repeats itself exactly. A magnet wand comes with it if you want to push the fluid around by hand.

Liquid in motion: the ferrofluid reacts to whatever is playing, with peaks that rise and collapse on the beat.
Two ways in: connect over Bluetooth or plug in the supplied AUX cable.
Lit base: the platform glows while audio runs, which shows the fluid against a dark room.
Magnet wand: included, so you can shape the fluid yourself with the sound off.
Long session: 8 to 10 hours on a full charge, refilled over USB-C.

Set it near the speakers and let the track do the work.

The housing is ABS with a glass sphere on top, 10.6 x 9.8 cm in total, so it sits on a desk corner or a shelf without crowding anything. Three finishes are available: white, black, and wooden grey. The USB-C cable is in the box.
