2B30.47 - Egg in a Bottle

Code Number:
2B30.47
Demo Title:
Egg in a Bottle
Condition:
Good
Principle:
Air Pressure
Area of Study:
Heat and Fluids
Equipment:
Milk Bottle, Hard boiled egg with shell removed, matches.
Procedure:

Take several matches, light them and put them into the bottle.  Immediately after they go out place the egg over the mouth of the bottle.  As the air in the bottle cools the egg should be forced into the bottle.  Invert the bottle and blow into the bottle as hard as you can to increase the pressure inside.  The egg should then be forced out of the bottle.
