Summary: The well-known Laplace-Young equation asserts that the pressure difference across the film or a membrane in equilibrium is proportional to the mean curvature with proportionality constant being the surface tension of the interface. Here we present two variants of this equation leading to Delaunay surfaces and to mylar balloons, and in this way we provide their nonvariational characterization.
