Drainage via stratification of micellar foam film formed by an aqueous SDS solution, visualized in reflected light microscopy. Each shade of gray corresponds to a different thickness. Stratification proceeds via nucleation of thinner darker domains, and number of steps increases with concentration, whereas step-size decreases with concentration.
