Egg sucked into bottle
A hard boiled Egg. A bottle with a neck slightly narrower than the egg Result. You should find that the egg is slowly sucked into the bottle. If students believe 'using up oxygen' is what causes the egg to be sucked into the bottle challenge them to design an experiment to prove or disprove this theory. This creates a lower pressure inside the bottle than outside the bottle. The greater pressure outside the bottle forces the egg to get sucked into the bottle. Sucking an egg into a bottle; Sucking an egg into a bottle. You should find that the egg is slowly sucked into the bottle. Explanation. This means that the air pressure inside the bottle will reduce allowing the air pressure outside to push the egg into the bottle. And because a boiled egg is very rubbery and flexible you can get it. The egg in a bottle demonstration is an easy chemistry or physics demonstration you can do at home or in the lab. You set an egg on top of a bottle (as pictured). You change the temperature of the air inside the container either by dropping a piece of burning paper into the bottle or by directly heating/cooling the bottle. The air outside then tries to get into the bottle to fill up the vacuum, thereby forcing the egg to get sucked inside. In this connection, it may be mentioned that hard boiling an egg increases its intermolecular spaces causing it to become quite flexible, making the experiment possible.
