Abstract
A classical membrane model is developed for a dynamic wormhole. Its throat expands hyperbolically with an acceleration proportional to the surface energy density . The model leads to a negative bulk viscosity coefficient on the throat, expressing the instability against perturbations (expansions or contractions).
