Four wooden tables with table lamps are placed in a row. There is a laud-speaker on each table. The loudspeakers are placed like plates (with the membrane facing up) and are filled with water. At each table a different sound can be heard.
As one hears the artist talking or making vocal sounds the vibration of the loudspeakers membrane is turned into the waves on the water surface. The relationship between the meaning of what is heard and the wave pattern may be observed.
