Bottled Eggs-periment
YOU WILL NEED

One peeled, hard-boiled egg
Plastic or glass bottle with an opening slightly
smaller than the egg
Large bowl of hot water
Large bowl of ice water


HERE’S HOW

Put the bottle in the bowl of hot water for about five
minutes.








Move the bottle to the bowl of ice water. Wet the egg
and place it pointed side down in the bottle opening. As
the air inside the bottle cools, the egg will slowly move
into the bottle.







To remove the egg, hold the bottle upside down so the
egg is near the opening. Blow hard into the bottle with
your mouth tight against the opening. Point the bottle
away from you: The egg flies out!







WHY?

Hot air expands. Cold air contracts. When the air inside
the bottle is heated, the molecules, or tiny air particles,
inside the bottle spread out, increasing air pressure. As
the air in the bottle cools, the air pressure decreases.
The greater outside air pressure pushes the egg into
the bottle. Blowing into the bottle raises the air
pressure again. The air and the egg rush out of the
bottle
