Egg in a Bottle

Egg in a Bottle | Science Fair Projects | STEM Projects
Ever wondered how an egg can fit into a bottle? In this experiment, you'll find out how air pressure can push an egg into a bottle.


The hypothesis is that air pressure can push an egg into a bottle.

Method & Materials

You will peel the shells off two hard-cooked eggs, place one of the eggs on the mouth of the jar, and observe the egg after dropping two well-lit matches into the jar.
You will need a narrow-mouthed jar, two hard-cooked eggs, and wooden matches.


The egg was pushed into the jar by the air in the room. It is a misconception to say it was "sucked" into the jar. When the balance of pressure was changed, the egg moved.

Why do this project?

This science project is interesting and unique because it shows how air pressure can be used to move an object.

Also Consider

Experiment variations to consider include using different sizes of eggs and bottles, or using different types of matches.
