Continuous chain of bubbles in concentrated polymeric solutions

Abstract

Motion of bubbles in a liquid is a ubiquitous yet very nontrivial phenomenon. The available body of knowledge and even its language connotation consider bubbles only as a discrete, detached from each other, units. It turns out that in concentrated polymer solutions bubbles may form a qualitatively new structure. The experimental study reported below shows that bubbles may form a very stable, continuous, slowly rising, connected long chain similar to beads, or bubble “sausage.”
