This mosaic features air bubbles (2-2.5 mm in radii) rising through water and sequences of others in the background. Bubbles pass through a sound field whose waves cause non-linear interactions between the air-water interface, which produce surface irregularities and pinch-off smaller bubbles. From the bottom to the top of the photograph bubbles are formed, rise, oscillate, and breakup into smaller bubbles (time differences between consecutive vertical images is 5.5 ms). The breakup is efficacious for minimizing potential air emboli during open-heart surgery.
