Chem 121: Chocolate Mousse and Elemental Business Cards

We’ve been learning about colloid: one phase of matter dispersed in another. This classification of matter includes foams, slurries, smoke, jello, clay, homogenized milk, and many other substances. What better way to learn than to make a delicious colloid – chocolate mouse – a dispersion of chocolate fat and air in water.
