The flows inside the liquid phase of a liquid foam are largely unkown. However, they are at the origin of the foam stability and viscosity, which are two important quantities in many industrial processes. A closer look inside foam films is thus not only beautifull but also usefull. See other videos from the 2018 Gallery of Fluid Motion: https://gfm.aps.org/
