Thin elastic films that can spontaneously attach to liquid interfaces, thereby offering a platform for tailoring their physical, chemical, and optical properties. Curved shells can be used to manipulate interfaces in qualitatively different ways. For example, an ultrathin shell with vanishing bending rigidity can impose its own rest shape on a liquid surface, in a process where the pressure across the interface inflates the shell into its original shape. The approach is amenable to optical applications as the shell is transparent, free of wrinkles, and may be manufactured over a range of curvatures.
