Popping bubbles captivate our childish sense of wonder and our scientistific passion to unravel the observation.  On face value, the behavior of a ruptured soap film is seemingly simple, however, the patterns that emerge are intricate. Our video uses the sublimation of frozen carbondioxide to visualize the complex characteristics of this phenomenon.  We show how the rupture forms both a flapping flag like instability and Rayleigh-Plateau fingering. The fog allows us to see the resultant wake inside the bubble as the film receeds.
