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 foam:

    “To dine!” she shrieked in dragon-wrath.
    “To swallow wines all foam and froth!
    To simper at a table-cloth!”

    To join the gormandising troop
    Who find solace in the soup?
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    Yet ere I can say where—the chariot hath
    Passed over them—nor other trace I find
    But as of foam after the ocean’s wrath
    Percy Bysshe Shelley (1792–1822)

    And his wish is intimacy,
    Intimater intimacy,
    And a stricter privacy;
    The impossible shall yet be done,
    And, being two, shall still be one.
    As the wave breaks to foam on shelves,
    Then runs into a wave again,
    So lovers melt their sundered selves,
    Yet melted would be twain.
    Ralph Waldo Emerson (1803–1882)
