Featured Scientists – Diego Baresch & Axel Huerre

Diego & Axel work in the Garbin Research Group at Imperial College London. He invites you to experience a beautiful way to visualize sound, by observing a soap film trapped in a bottle’s neck. Music emitted from a speaker forces the bottle to resonate for a particular set of musical frequencies. A fascinating consequence is that the colour bands that appear on a soap film… cannot help it! They start to move and dance in synch with the music in a very graceful way. The sound/light interaction experiment is triggered by complex hydrodynamic effects taking place within the bottle including acoustic vibrations, capillary waves and 2D turbulence patterns.
