Royal College of Art graduate Dagny Rewera used soap and light to create this audiovisual display highlighting the microscopic appearance of sound.
For the Invisible Acoustics project, Dagny Rewera set up three speakers with lights attached. To visualise the sound emitted, the designer developed an automated system that dips a hoop into a soap solution and holds it directly above the speaker.
When switched on, the sound waves cause the soap bubble to vibrate. However, these tiny aberrations aren't visible to the naked eye, so a lens is suspended above the soap to magnify the microscopic changes in the surface of the bubble. The results are then projected on to the ceiling, creating a dazzling display.
