In common with other areas in which fluid dynamics plays an important role, the physics of foams is strongly influenced by gravity. In particular this poses difficulties in studying the equilibrium of wet foams. This is the primary motivation for some recent proposals for microgravity experiments under the auspices of ESA and NASA. At a more practical level, the microgravity environment should greatly extend the range of possibilities for the fabrication of metallic foams, in terms of alloys, additives, pore size and relative densities.
