We participated JSME 14th Dreams of Flow Contest held at Tokyo University Science of as Team LCS×SATUKI. In this article, we describe the outline of Music Awa ~Music hour~.

The theme of Dreams of Flow Contest is “Japanese healing and welfare”, so we focused on Japanese healing. Music Awa ~Music hour~ based on Japanese lighting equipment called “Andon” (Fig.1). Music Awa ~Music hour~ contains a variety of gimmicks.

First, we created a device that oil bead, such as the bubble are ups and downs (Fig.2). It contains benzyl alcohol (C6H5CH2OH) colored in orange and salt water in the bottle. When it is warm from the bottom of this bottle in heat of an incandescent lamp, the specific gravity of benzyl alcohol is smaller than salt water, and floats benzyl alcohol. After benzyl alcohol is raised, benzyl alcohol back specific gravity by being cooled at the top and moves to the bottom. Such ups and downs of benzyl alcohol is repeated.

Second, we created a Laser Harp as a device that music plays.
Laser Harp is likened to string of the laser light, music is played by blocking the laser light. Cds cell is the role of the light sensor (Fig.3). The opposite of Cds cell is installed laser pointer, and it is always in a state where the laser light hits the Cds cell (Fig.4). When benzyl alcohol ups and downs, and refracts the laser light, music plays by laser light being blocked at the Cds cell.

Finally, we demonstrated “Music Awa ~Music hour~”
On the contest day, we presentation and demonstrated to show ups and downs of benzyl alcohol and the music from a laser harp to many people (Fig.5).
