Abstract

The thickness profiles of the aureole created in the bursting of vertical soap films are studied by a fast line scan charge-coupled device camera. Detail dynamics of the aureole are reported. Phenomena of the wavelike motions of the bursting rim and detachments of the aureole from the bursting film are also observed. We find that the stability of the aureole increases with the surfactant concentrations and is sensitive to the types of surfactant being used. The concentration dependence suggests that the interaction of micelles might be important in the bursting process. Furthermore, the surfactant monolayer in the aureole is found to be highly compressed and behaves like a rigid film. Existing theories of the aureole formation cannot account for all the observed phenomena.
