Today I will be explaining the flying teabag experiment that we did.
First we emptied out the tea from the tea bag and stood the bag onto a sheet of tinfoil so we didn't burn the table. Then we got a lighter and lit the top of the bag, then we watched it burn down the tea bag until it got short enough that the cold air in the room could rush into the bottom of the tea bag and make it fly upwards. Although it only flew for a few seconds it still was flying. The reason for the tea bag flying was because the tea bag was lighter than the air in the room. The tea bag became lighter than the air because the flames burnt away the molecules which made the tea bag heavier.
Has anyone else done this experiment?
