Foams
A foam is a substance that is formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas.

Famous quotes containing the word foams:
“This fantastic state of mind, of a humanity that has outrun its ideas, is matched by a political scene in the grotesque style, with Salvation Army methods, hallelujahs and bell-ringing and dervishlike repetition of monotonous catchwords, until everybody foams at the mouth. Fanaticism turns into a means of salvation, enthusiasm into epileptic ecstacy, politics becomes an opiate for the masses, a proletarian eschatology; and reason veils her face.”
—Thomas Mann (1875–1955)
