The hot air balloon consists of a dome, fireplace, and a basket that holds the passengers. The basket is made of straw so it is light and flexible. The stove is located at the top of the basket to effectively heat the air. The dome, the balloon itself, is usually made of anti-tear plastic. A fire resistant material such as Nomex is used in the open part of the balloon. Although all hot air balloons are made up of these three parts, each balloon varies in size, shape, shrinkage system and number of burners. The main working principle of hot air balloons is to cause the hot air inside the balloon to rise, while the air inside the balloon causes it to descend.
