They are a mixture of two states of matter (phases). Bubble bath foam is a liquid/gas mixture. (Liquid round the edge and gas in the middle) Other examples of 'two phase' mixtures are: Smoke (solid and gas) Fog (liquid and gas) Emulsions (can be solid and liquid like paint or liquid and liquid like mayonaisse) Clay (solid and liquid) Meringue (when crispy) (solid and gas) When the two substances are very finely divided they are termed 'colloids'. Other related terms you could look at are 'gel' and 'sol' I find colloids great sources of extension work when teaching young scientists about states of matter. Good examples in foods and tactile substances ... enjoy :)
