Video of a Floating Hot Air Balloon

A floating hot air balloon is a type of aircraft that uses a large bag, called a "balloon," filled with hot air or a mixture of hot air and gas (such as helium or hydrogen) to rise into the air. The balloon is typically made of lightweight, heat-resistant materials such as nylon or polyester. The hot air is generated by a burner, which is fueled by propane or other gases. The pilot controls the altitude of the balloon by adjusting the heat in the balloon and the amount of gas in the envelope, as well as by using the wind currents to navigate. Hot air balloons are often used for sightseeing and recreational purposes, but they can also be used for scientific research, wildlife management, and other purposes.
