Unit 5 - Heat and light

As you probably know, heat rises! Hot air balloons work at lifting a balloon off the ground by making the air inside the balloon hotter, and ultimately less dense, than the air outside. Similarly, this tea bag flying machine lifts off once the fire burns the tea bag into lightweight ash. The rising hot air current lifts what’s left of the bag and blows it into the air.
