    "abstract": "We present a quasi-two dimensional model of flowing soap films that bears\nstriking similarity to the compressible Navier-Stokes equations. The variation\nin soap film thickness that is commonly used for flow visualization in\nexperiments is analogous to density variations in the Navier-Stokes equations.\nWhen the soap film flow velocity is comparable to the Marangoni elastic wave\nvelocity we recover the compressible Navier-Stokes equations and the soap film\nbehaves like a two-dimensional isothermal viscous gas.",
