HEAT vs. the EGG
Place the egg on the mouth of a Vita Water bottle. The egg is to big to go through (make sure it is a peeled hard boiled egg). Take a cotton ball, soak it in rubbing alcohol, drop it in the bottom of the bottle, light it on fire with a lighter, hurry and put the egg on top and watch what happens. It is amazing how those heat molecules expand and then retract the way they do!
