The egg on top creates a seal. As the air inside gradually _________, the air contracts and takes up less space. Outside air cannot __________ because the egg now seals the top of the bottle. The air pressure inside the bottle is _________ than the pressure outside and so it forms a partial vacuum. This ______________ the egg to get sucked into the bottle.
