A foam is produced by trapping millions of tiny gas bubbles in a liquid (whipped egg white) or a solid (marshmallow). Whisking water and air produces hundreds of bubbles but they soon 'pop', leaving only water and air again. Eventually the protein coating of the air pockets link together, making a foam.
