How does the egg in the bottle trick work?

In this demonstration, the lit matches heat the air inside the bottle. When air is heated it expands and some of it escapes out the bottle. When the matches go out, the air inside the bottle cools and contracts (takes up less space), thus creating a lower air pressure area inside the bottle than outside.

Why did the egg fell down inside the bottle?

When the air contracts, the air pressure inside the bottle becomes less than the air pressure outside the bottle. This gives the higher air pressure outside of the bottle the opportunity to push the egg down into the bottle.

How do you put an egg inside a bottle without breaking it?

Peel your hard boiled egg and make sure all the shell is removed. Place the egg in the neck of the milk bottle, to check that the egg will sit neatly in the top of the milk bottle and that it won’t slip through.

How does an egg get in a bottle with hot water?

  1. First get permission to use kitchen equipment and eggs. Then put the bottle in the bowl of hot water for about five minutes.
  2. Move the bottle to the bowl of ice water. Wet the egg and place it pointed side down in the bottle opening.
  3. To remove the egg, hold the bottle upside down so the egg is near the opening.

What happened to the pressure inside the bottle when it was squeezed?

When the walls of the bottle are squeezed, the pressure increases inside the bottle. This added pressure decreases the volume of the gas in the bottle, including the gas in the medicine dropper. This is Boyle’s Law.

What happens when you leave an egg in water for 24 hours?

Leave the egg in the water for 24 hours. The water will migrate from the side of the membrane where water molecules are abundant (outside the egg) to the side where water molecules are less abundant. After 24 hours, the egg will be plump again.

What gas law is applied in an egg in a bottle?

Gay-Lussac’s Law
Gay-Lussac’s Law helps explain the egg-in-a-bottle trick, where boiled water displaces the air inside a bottle, and as the water condenses, an egg placed over the bottle will be pulled inside because of the change in pressure inside the bottle.
