concerning the system instruments: 4 x glass tubes as observation spaces 2 x lights as heaters 4 x microphones + loudspeaker with 4ch selfbuild amplifier as audio amplification method: setting 2 x glass tubes in the normal thermal state and 2 x tubes in the heating state. catching the internal sound at one of the glass tubes and transmitting the sound to the next space. doing this procedure over and over. as a result, the natural resonance frequencies must be emphasized. in this case, 2 sets of resonances will rise from 2 kinds of thermal states. the difference between thermal states appears as beat.
