Summary

This text is about the physics of foam. For the theoretical basics there are explanations for surface tension, which gives the necessary energy to enlarge the surface, surfactants, which stabilize the foam even is the layers are very thin and the Laplace-pressure. Then the principals of the foam decay (evaporation, drainage and coarsening) are presented. To describe the decay an exponential fit is used.
