I saw an episode of Good Eats this weekend ('There will be oil') with cooking oil as the topic. Alton Brown explains the chemical structure of oils, including what is meant by saturated, monounsaturated, and polyunsaturated, by making them out of balloons!
Definitely worth a watch, the balloon action begins at minute 2 in the video below. The black balloons represent carbon atoms, and the hydrogen atoms are the yellow balloons.
