Teabag Rocket Experiment

Earlier this term we began building our knowledge of flight.  There was a keen interest in hot air balloons and students were introduced to the concept that hot air is lighter than cool air.  To test this theory we carried out the teabag rocket experiment.  As you will see, the flame burns down the cylinder and heats the air inside of the tea bag.  Faster moving air molecules in the hot air rise and the cooler air settles beneath.  The rising hot air creates an upward force called lift and as the flame gets closer to the bottom, the ashes become light enough to fly.
