image: A viscous bubble film with sufficiently large viscosity, will collapse under the force of surface tension and adopt a wrinkling pattern along its periphery. This material relates to a paper that appeared in the 7 Aug., issue of Science, published by AAAS. The paper, by A.T. Oratis at Boston University in Boston, MA, and colleagues was titled, "A new wrinkle on liquid sheets: Turning the mechanism of viscous bubble collapse upside down."
