Egg in a Bottle Experiment 🥚ages 3+ 🥚This simple science experiment with amaze everyone and is a great lesson on air pressure.
Before reading the tutorial, check out the Egg in a Bottle Experiment in action in the below video:
MATERIALS NEEDED FOR EGG IN A BOTTLE EXPERIMENT (affiliate links):
- 1 peeled, hard-boiled egg
- 1 glass milk bottle (or any glass bottle with a mouth slightly too small for the egg to fit through)
- A small piece of paper
- A match or lighter
- Vegetable oil (optional – we used a paper towel to rub a bit of vegetable oil on the inside of the glass bottle opening to help the egg move through)
HOW TO DO THE EGG IN A BOTTLE EXPERIMENT:
1. Hard boil an egg.
2. Peel the hard-boiled egg so the shell is completely removed. Optional: rub a little oil on the inside of the glass bottle rim to help the egg move through.
3. Test pushing the egg into the bottle. Notice it will not fit through the neck of the bottle.
4. Have an adult light the piece of paper of fire on one end and quickly drop it into the glass bottle.
5. Place the egg on top of the bottle immediately.
6. Watch as the fire fizzles out and the egg starts squeezing through the bottle.
7. Try turning the bottle upside down and you’ll find that the egg is stuck inside the bottle!
8. To remove the egg from the bottle, use a small spoon or knife to break it up into smaller pieces.
WHY DOES THIS HAPPEN?
As the fire goes out and the air cools in the bottle, the air contracts and the pressure of the air in the jar is less than the air outside the jar. The higher pressure air outside pushes the egg inside the jar. So cool! 👍🏻
