Egg In A Bottle Magic Science Experiment
Do you think it is possible to put an egg inside a bottle with an opening that is smaller than the egg? In this fun and easy science experiment, we’re going to show you how to put an egg inside a bottle. Being able to do this seemingly impossible task may appear magical but we will show you it’s just science.
Important – This experiment requires adult assistance and supervision due to the use of matches.
Materials:
- A bottle with a wide mouth – check to make sure that the egg is slightly larger than the opening of the bottle
- Hardboiled egg
- 3 matches
- Small piece of paper – about one inch by one inch
Instructions:
- Place the egg on top of the bottle to demonstrate that the egg will not fit inside.
- Now remove the egg.
- Drop the piece of paper inside the bottle.
- Have an adult assistant strike the three matches together until they burst into flame.
- Have the adult quickly drop the matches inside the bottle.
- Immediately set the egg onto the top of the bottle making sure it is sitting snuggly.
- As the matches go out, observe what happens to the egg.

How it Works:
The matches heat up the air inside the bottle. This causes the air to expand and some of it even escapes. Once the matches go out, the air inside the bottle cools and contracts. This lowers the air pressure inside the bottle. The higher air pressure outside of the bottle seems to magically push the egg inside.
Make This A Science Project:
Are there other ways to reduce the air pressure inside the bottle and cause the egg to go inside?
