Egg in the bottle - 2!

The Egg in the Bottle activity explores air pressure differences more dynamically. In this version, an egg is placed on a bottle cap, and a wide-mouth bottle is inverted and carefully heated from below using a lighter. When the bottle is placed over the egg, the air inside the bottle cools, creating a pressure difference that pulls the egg upward. Alternatively, this experiment can also be performed by placing a burning piece of camphor on the egg before inverting and placing the bottle over it. In both cases, if the pressure difference is strong enough, the egg gets sucked inside. 

Learning Objective:

To demonstrate the effects of air pressure changes through heating and cooling, showcasing the power of pressure differences and their influence on physical movement and force.
