Research Abstract

A vertical soap film was made by pulling rapidly a metallic frame out of an additive free soap solution. Nonequilibrium pattern formation and growth in the thinning soap film was observed on a reflection interference microscope. No nonequilibrium pattern was observed in soap films made from three types of surfactant aqueous solutions including 0.1 M sodium oleate aqueous solution. Quantitative phase microscopy allowed us to find emergence of a large step over 400 nm in a thinning soap film made from 0.1 M sodium oleate aqueous solution.
