A new piece of the puzzle : Bubbles represent one of the simplest and most pervasive entities in the world around us, occurring in almost all liquid systems. The controlled collision between two microbubbles in water was investigated (see experimental setup) to understand the effect of gas type and solution pH on their stability, using ubiquitous gases—pure CO 2 , air, nitrogen, and argon.
