What Kids Learn From This STEAM Activity
In the STEAM activity, Egg in a Bottle, kids learn about air pressure and the scientific method. They place a hard-boiled egg on the mouth of a bottle, then use heat to create higher pressure inside the bottle. When you heat the air inside a closed container like a bottle, it expands and creates higher pressure. When you stop heating it, and the air cools down, it contracts, creating lower pressure inside compared to the outside. This pressure difference causes the egg to be pushed into the bottle because air always moves from high-pressure areas to low-pressure areas. This activity teaches kids about the relationship between temperature, pressure, and gases, fostering an understanding of basic physics principles in a fun and hands-on way.

What We Need For This STEAM Activity
STEAM Activity, STEM Activity Egg In A Bottle Materials- Glass bottle with narrow mouth
- 1 Peeled hard-boiled egg
- A lighter or match
- 1 Small piece of paper
How to Do the STEAM Activity Egg In A Bottle
- Ensure that the glass bottle has a mouth that is smaller than a hard-boiled egg can go through.
STEAM Activity, STEM Activity Egg In A Bottle – The Glass Bottle Has Mouth That Is Smaller Than a Hard-boiled Egg Can Go Through. - Ignite the paper: Light a small piece of paper on fire using matches or a lighter. (Kids need adult’s help and supervision.)
STEAM Activity, STEM Activity Egg In A Bottle – Ignite The Paper - Drop the paper into the bottle: Quickly drop the burning paper into the bottle and place the egg on top immediately.
STEAM Activity, STEM Activity Egg In A Bottle – Drop The Paper Into The Bottle - Observe the magic: Watch as the egg gets pulled into the bottle as the paper burns out. It’s due to the change in air pressure inside the bottle.

Variations & Challenges
- Attempt to fit multiple eggs into the bottle at once for an added challenge.
- Encourage kids to explain the scientific principles behind the experiment, such as air pressure and temperature, to deepen their understanding.
