Science Discipline(s) Chemistry Topics Air pressure Combustion Activity Title Egg in a Bottle Demonstration Materials
- Hard-boiled egg
- Glass bottle with an opening that the egg will not slip into
- Cotton balls
- Rubbing alcohol or ethanol
- 2 100 mL beaker
- Baking soda
- Pie plate
- Hair dryer (optional)
- Pour rubbing alcohol or ethanol into a beaker
- Pour vinegar into a beaker
- Boil eggs and peel hardboiled eggs
- Place egg on the opening of the bottle
- Take a cotton ball and soak in alcohol or ethanol
- Light a match to light the cotton ball on fire
- Remove the egg from the bottle and drop the lit cotton ball into the bottle
- Quickly place the egg on top of the bottle
- Observe the egg being pulled inside the bottle
- Tip the bottle with the egg in it so that the egg lays near the opening of the bottle (try to aim the egg pointing straight towards the opening of the bottle)
- Put baking soda all around the egg, especially on the sides
- Pour in vinegar and quickly flip the bottle upside down with the egg closing the opening above the pie plate
- What is air pressure?
- How do you think the egg is going to get into the bottle?
- What happens to the air pressure when air is heated?
- How is the reaction between baking soda and vinegar get the egg out of the bottle?
