Query: Bubbles and liquid films resisting drainage, evaporation and
  nuclei-induced bursting   Soap bubbles are by essence fragile and ephemeral. Depending on their
composition and environment, bubble bursting can be triggered by
gravity-induced drainage and/or the evaporation of the liquid and/or the
presence of nuclei. They can also shrink due to the diffusion of the inner gas
in the outside atmosphere induced by Laplace overpressure. In this paper, we
design bubbles made of a composite liquid film able to neutralize all these
effects and keep their integrity for more than one year in a standard
atmosphere. The unique properties of this composite film are rationalized with
a nonlinear model and used to design complex objects.
