Hot Air Baloon

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. Pilots have a great deal of control over the altitude of the balloon which they monitor with various instruments. They develop incredible anticipation skills over time and can often control a balloon’s descent within centimeters.
