The physics behind bursting bubbles (1 of 2)

Date:23 June 2010 Tags:,

In this video, the interfacial bubble ruptures, uncovering a dimple on the water surface. The high curvature of this dimple causes a jet to form; since this jet does not have enough kinetic energy to be propelled into the atmosphere it returns to the interface. Yet, around the jet, there is a ring of smaller bubbles formed during the film retraction. One of these daughter bubbles ruptures at 56 ms (left side of movie).
