 Abstract liquid foams undergo a transition from a dry state to a wet state when they are exposed to moisture. This transition is characterized by a dramatic increase in the number of collective rearrangement events, which can be observed through the simultaneous occurrence of multiple T1 events. The probability of these events occurring follows a Poisson distribution, indicating that there is no correlation between them. These findings provide insight into the dynamic behavior of soft jam systems, which have applications in biology, materials science, and food science.
