another response for why they really fly is this.. Hot air balloons can achieve flight because of the law of buoyancy, also called Archimedes’ principle. Archimedes’ principle states that an object in fluid (gas or liquid) is acted upon by an upward force equal to the fluid displaced by the object. Since hot air is lighter than normal air, the balloon is buoyant.
Because their fun to ride in and beautiful to see from the ground :)
Well it has a gas fueled flame and the flames heat makes the balloon part fill up with hot air. Hot air rises so the hot air balloon will float into the sky like a helium balloon would.
In a "hot air" balloon, which you refer to in your question, the gas is hot air. Heated air rises, so the balloon rises. The gas used in the burner, to heat the air, is propane.
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
I think the hotter the fire is ( I'm not really sure on how to make fire hotter! :) sorry!) the higher the balloon goes. because hot air rises and so it seems right that if the air is hotter it will rise higher. if you are reading this answer then, you rock!!
To go up. "The hot air balloon ascended in the morning sky."

There is a candle at the bottom of the lantern. the candle will then be lighted and hot air rises, which makes the lantern fly. its the same logic as a hot air balloon

a hot air balloon works when the hot air blowing from the bottom pushes up the balloon which lifts it up into the sky where it moves in the direction where the wind blows .
To the sky,of course.
Helium is lighter than air, therefore it rises upwards.
It falls out of the sky and you die

In a hot air balloon high in the sky
There is hot air to make it fly and there are weights to stear it.
