Egg in a Bottle

Turn your kitchen into a laboratory and wow your kids with this simple science experiment from TV crafter Jim "Figgy" Noonan.

What is happening?
The newspaper burns until all of the oxygen in the bottle is consumed (or the paper is consumed, whichever comes first). The burning heats the air in the bottle, increasing its pressure and causing it to expand. The heated air makes its way out of the bottle, pushing the egg out of the way in the process, making it appear to jump on the opening of the bottle.

When the flame goes out, the air cools, and the egg seals the mouth of the bottle. Now there is less air in the bottle than before which exerts less pressure and creates a slight vacuum. The combination of the vacuum in the bottle and the higher air pressure outside the bottle pulls/pushes the egg into the bottle.


All tools and materials available at your local grocery store.


  • Glass milk bottle (or similar glass container)

  • Hard-cooked egg (peeled)
  • Vegetable oil

  • Newspaper

  • Matches or lighter


  1. Select a milk bottle (or similar glass container) with an opening slightly smaller than the diameter of the egg.
  2. With your finger, apply a small amount of vegetable oil to the inside rim of the opening, providing a bit of lubrication for the egg to enter the bottle.

  3. With matches or a lighter, ignite a small piece of newspaper and drop it inside the bottle.

  4. Immediately place the egg on top of the mouth of the bottle with the smaller, pointed end facing downward.

  5. When the flame goes out, the egg will be pulled into the bottle.
