There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
Hot air balloons float because hot air displaces cool air in the atmosphere
People think that hot air balloons where made for battles.
Circles and spheres have the least amount of surface area per volume than any other shape, and so it is a very popular shape for hot-air balloons as less heat is dissipated through the skin of the balloon.That being said, hot-air balloons have been made in many different shapes.
