Burning natural gas to heat the air in the balloon and dropping weights both make the balloon rise, letting hot air out (through vents near the top) makes the balloon sink.
These maneuvers allow the pilot to find air masses that move in the desired direction. No horizontal control is available other than the movement of surrounding air.
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

Hot air balloons are usually shaped like an egg because it is an easy to fold and inflate shape. However there are hot air balloons shaped like cartoon characters or advertising symbols. There are people that specialize in creating unique shapes for hot air balloons.
By releasing some of the hot air in a very controlled manner.
The hot air balloons air pressure is usually used to explain the principle of buoyancy.
There is a valve to release hot air from the top. The amount of hot air you let out from the top is replaced with cooler air from the bottom, causing the balloon to descend.
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
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
This may not help, but I didn't think it had ANYTHING to do with hot-air balloons...

Modern hot air balloons do not have sand bags because the air input is easily controlled for lift. Hot air balloons used to have sandbags to weigh them down until lift off and sand was gradually dumped to gain height in the air.
