Sucking An Egg In A Bottle- Science Experiment

What You Need:
1 hard-boiled egg, peeled
1 long-necked bottle
3 matches

Demonstrates Science Category: Physics (Thermodynamics)
Ages: Elementary Science (Adult Assistance Required), Middle School Science (Adult Assistance Required), High School Science (Adult Assistance Recommended)

Caution: Experiment MUST be done with adult assistance and supervision!

I recommend these printable science project plans for K-12 for hundreds of great project blueprints and this step-by-step guide for doing an award winning science fair project. Also be sure to check out these fun science kits as a fast, simple way to get started on your science experiment.
What To Do:
1) Hard boil an egg and allow to cool. After the egg cools, peel off the ****l.
2) Place a long-necked bottle on your kitchen table (or any table free from flammable debris)
3) Have an adult light 3 matches and place in the bottle (all matches at once, not one at a time)
4) Quickly put the egg on top of the bottle opening



3 minutes



Demonstrates scientific principles:
The matches heats the air, which causes it to expand. When the matches extinguish, it causes the air to contract as it cools. A lower pressure is created within the bottle, than on the outside. The pressure outside the bottle causes the egg to get sucked into the bottle.
Heat causes most solids and liquids to expand, and cooling causes them to contract. Atoms or molecules within the solids vibrate more quickly with the increased heat. This causes the solid/liquid to become larges, and when cooled, become smaller.
