We separate mineral ores by flotation inside huge tanks of foams. We beat eggs. We drink beer and champagne. Our cosmetics are often based on foams, not for technical reasons, but because they are more pleasing to the touch.
Many fire extinguishers use foams.
One form of oil recovery uses foam injection, which introduces many problems of its own. In some other industrial processes, we must kill a nuisance foam, using cleverly formulated additives. Thus foam science is very much alive. Until recently, publications in the field were either scattered or collected in compendia with many authors. The Physics of Foams opens with a simple presentation of key features of foam architecture, including the basic Plateau rules for the intersection of three films.
