Although soap films are prone to evaporate due their large surface volume ratio, the effect of evaporation on macroscopic film features has often been disregarded in literature. In this work, we experimentally investigate influence environmental humidity stability. An original experiment allows measure both maximum length a pulled at constant velocity and its thinning dynamics controlled atmosphere for various values relative RH. At first order, seems have almost no impact most dynamics. However, find that rupture increases continuously with To rationalize our observations, propose bursting occurs when becomes comparable liquid drainage. This criterion turns out be reasonable agreement an estimation rate experiment.
