How a Hot Air Balloon Works?
Hot air rises faster than cooler air around it. Hot air balloons take advantage of this effect to lift a balloon and attached basket into the air. The balloon is basically like a big parachute with a semi closed end with a small opening. Into that opening the burner shoots very hot air, as the hot air rises the balloon fills and lifts off the ground. However, the burner has to keep heating the air in the balloon or it will cool and fall (slowly) to ground. To find more information click here: http://www.howstuffworks.com/hot-air-bal…
