US Patent 10478831 Bioluminescent tornado maker system

A bioluminescent tornado maker system for creating a pleasing, glow-in-the-dark tornado. The bioluminescent tornado maker system generally includes a base that supports a transparent vessel having a liquid within it. The liquid may be salt water, and may contain bioluminescent organisms, such as dinoflagellates. An impeller in the base in contact with the liquid causes a rotational flow of the liquid, creating a visible vortex and also a mechanical disturbance that causes the bioluminescent organisms to emit a visible light, resulting in a glow-in-the-dark tornado.
