Abstract

We consider the dynamics of capillary attraction between an articulated train of rigid rods floating at a liquid–gas interface and a nearby wall. We then explain some of the phenomena that are a result of the strong anisotropy and the extended nature of the system, such as the lining up next to the walling in a ‘zippering’ motion that is observed and compare our results qualitatively with those of experiments.
