Marginal regeneration-induced drainage of surface bubbles

When a soap film drains, marginal regeneration refers to the rise of patches that are thinner than rest film. In this work velocities and sizes buoyant measured found be in good agreement with Rayleigh-Taylor like instability model based on balance gravitational surface viscous forces, as suggested literature. Thus, an environment saturated humidity, eliminate evaporation effects, approximately describes drainage at apex draining bubble.
