First get permission to use kitchen equipment and eggs. YOU WILL
NEED 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. Text by Julie Vosburgh Agnone
