A dry foam consists of thin liquid walls separating gas cells, such as in soap suds. A foam is called wet when the liquid pools at the intersections of cell walls. It is well understood how to “decorate” the intersection of a weightless dry foam to produce a weightless wet foam in its equilibrium state. What happens if the cell walls are weighted? This investigation concerns how to decorate weighted foams, when the weight of the liquid is not negligible, and the weight of the liquid pooling at the intersection will play a role in the larger equilibrium structure of the foam.
