摘要：

We assess the question here whether a foam contains the same amount of water in the horizontal plane as in the vertical plane. We show using different measurements of the liquid fraction that, for foam of fine bubbles, with a Plateau border length lower than 0.4 mm, the liquid is not distributed homogeneously in the foam. We argue that this effect can be explained by a swelling of the films due to drainage and is dependent on the orientation of the films.
