ed this research, explains: Our streams of water carry microscopic bubbles and acoustic waves down to the leaf. There the sound field sets up echoes at the surface of the leaves, and within the leaf crevices, that attract the bubbles towards the leaf and into the crevices. The sound field also causes the walls of the bubbles to ripple very quickly, turning them into microscopic scrubbing machines. The rippling bubble wall causes strong currents to move in the water around the bubble, and sweep t
