Today in room four our teacher Mrs Stone decided to show us a tea bag trick. She got rid of the tea leaves inside of the tea bag and unfolded it. She made the teabag a pipe of sorts. Once she set it down on the chair she lit it on fire. The fire moved down the tea bag and then it flew into the air.
But why did it fly? How does it happen? Its all because of the heat. Heat is a form of energy and it always rises. Its like a hot air balloon the hot air that goes into the air pushes against the walls of the tea bag and once the fire reaches the bottom of the tea bag, the tea bag remains fly into the air.
