Innocent-looking bubbles can serve as a launching pad to spread bacteria from water into the air, according to a new study.

The study, published Nov. 15 in the journal Physical Review Letters, found that bacteria can manipulate the physics of bubbles in a way that enhances the microbes’ spread. For example, bacteria-covered bubbles can last for a much longer time than clean bubbles, even though the bubble’s surface thins out over time. Then, once they burst, these thinner bubbles create many more droplets, which are launched into the air at a faster rate compared with clean bubbles.
