The low Reynolds number dynamics of a thin layer of fluid bounded below by a flat horizontal boundary and moving buoyantly through a fluid of another viscosity and density is observed by means of model experiments and is described theoretically. Three distinct stages of growth were observed. The first stage is described by a linearized Rayleigh-Taylor instability, for which previous literature, present theory, and experiments exhibit close agreement. In this stage, disturbances of one specific… Expand
