These high quality glass milk bottles make an egg-cellent demonstration of air pressure: just add one hardboiled egg and a little bit of fire! If you place a lighted piece of paper inside the milk bottle and then place an egg on top of the bottle, the fire goes out and the egg is mysteriously pushed into the bottle, whole! A perfect demonstration of warm air expanding, and cool air contracting - it's the cooling of the heated air inside the bottle that allows the atmosphere to "push" the egg inside.
