Abstract
In 1990s, Internet was born and changed our life dramatically. It's said that biotechnology may change our life in the near future. Noctiluca is free-floating zooplankton lives in the sea. It is about as large as 1 millimeter and glow in a moment when it is stimulated. Noctiluca hasn't studied enough. This study tried to controll bioluminescence of noctiluca. Firstly, I cultivated noctiluca and made clear that general consumers can cultivate noctiluca if they manage properly. Secondly, I conducted an experiment of stimulation and realized that noctiluca is emitted light with reacting to a water current and a bubble. Finally, I could draw some signs like a nunber and a triangle to use noctiluca.
