Basically the working principle of a hot air balloon is so simple that "by heating the air inside the balloon to make it hotter than outside air".

As with most fluids, the laws of Archimedes can also be applied to the air because the air includes fluids. The Law of Archimedes: The floating force acting on an object dipped partially or entirely into a fluid is equal to the weight of the fluid that is maintained by the object. This principle is the basis for how the air balloon works.

The following will describe how the blimp works, first the balloon is filled with hot gas or hydrogen until the balloon can bubble and the volume of air in the balloon increases. This means the buoyant force will increase as well. When the buoyant force is greater than the total weight of the balloon, then at that moment slowly the air balloon will rise.

The balloon crew (basketball) constantly adds hot gas so that the balloon can reach the desired height. Once the desired height is reached the balloon crew can reduce the hot gas by opening the parachute valve until a balanced state is achieved, ie the buoyancy force with the weight of the balloon. It is at this time that a hot air balloon can fly in the air. But not only is it necessary for the balloon to fly, the balloon crew also makes use of the wind blow moving the balloon from one position to another.
