What is Ferrofluid？ Developed by NASA, the magnetic liquid was originally used in rocket ships to control fuel in zero gravity. In June 2020, Bock Warning, and Cyberslee, discovered that magnetic fluids could be used to create an art rhythm. Now, we've harnessed its power to bring you stunning graphics that enhance your listening experience.

Part of the material components of the ferrofluid of the product are: pure water, mineral oil, and nano-iron powder, all of which are non-toxic and harmless. lt is forbidden to use it in high temperature and sun exposure environment. Hightemperature (such as inside a car) and sun exposure environment will causethe liquid to expand and cause the glass bottle to burst. Ferrofluid - Design inspired by the Movie 《Venom》 The composition materials of ferromagnetic fluid are nano iron powder, mineral oil, brine/pure water, which are non-toxic and harmless materials. 360° PANORAMIC VISUALS The ferrofluid speaker utilizes an integrated transparent container, ensuring that you can admire the captivating sight of ferrofluid dancing to the rhythm of the music from any angle. 4-Color Adjustable Light BlackCyanBluePurple Ferrofluid speaker is a perfect gift at Christmas, birthday, holiday,Father's Day mother's Day thanksgiving Day.
