How does a fire balloon work?
Hot air balloons work because hot air rises. By heating the air inside the balloon with the burner, it becomes lighter than the cooler air on the outside. This causes the balloon to float upwards, as if it were in water. Obviously, if the air is allowed to cools, the balloon begins to slowly come down.
What is fire balloon called?
