Abstract
Foams consist of cellular liquid structures, or lamellas, that are filled with gas. Some type of surfactant is required in order for foams to form—they cannot occur in pure liquids. If a gas, such as air, is sparged into a liquid containing a surfactant, the surfactant will form a double layer around the gas bubble, creating a collection of spherical foam bubbles. Such foams tend to be unstable and readily coalesce or break due to their high liquid content. More stable polyhedral foam, of most interest to us, is formed as a result of mechanical stresses, and is much more stable or difficult to break. Breaking of foam occurs in three stages: drainage of the cellular liquid comprising the walls, breakage of the foam walls, and diffusion of the gas out of the foam cells.
