Kids Science Experiments - Egg Through a Bottle

When you are searching among the many kids science experiments that are out there, you should try to choose one that not only is educational, but entertaining as well for your son or daughter. Science should be interesting and fun, especially at an early age. Children, as well as their parents, love this particular experiment. It’s called, “Sucking an egg in a bottle.”

As always when conducting kids science experiments, there should always be adult supervision Here is what you will need:

1 hard boiled egg (peeled)
1 long necked bottle
3 matches

Demonstrated in this project will be Physics, specifically Thermodynamics. Don’t be intimidated by the technical words as this experiment is definitely appropriate for elementary school students

Now, boil and egg and set it aside allowing it to cool. When its room temperature, peel the shell off. Place the bottle on a table making sure there is nothing around it that may be flammable. Now have a responsible adult light three matches and place them inside the bottle all at the same time, not one at a time. Quickly, place the egg on top of the bottle opening.

The matches will heat up the air, which causes the air to expand. When the matches go out, it causes the air inside to contract as it cools down. Lower pressure is created inside the bottle, than can be found on the outside. The pressure outside of the bottle causes the egg to get sucked into the bottle. Pretty who science fair project huh?

What happens is that heat causes most solids and liquids to expand. Cooling whatever it is causes them to contract. The Atoms or molecules the solids are made up of vibrate more quickly with the higher heat. This causes the solid/liquid to become larger, and when it is cooled, it become smaller. I hope you enjoy all the kids science experiments I have on my site.
