Why does fire stay upright always, and never downward?

Because the hot gas from the flame is less dense than the surronding air and therefore rises. An experiment on the space shuttle, burning a candle in 0 G produced an almost sperical flame because although the density of the hot gas was still less there difference in weight was eliminated.

The process of combustion creates hot gasses. The hot gasses expand and is lighter than the heavier dense air. the flames are carried upward by the moving gases.
The question I have. How would the flame look if you lit a match in a weightless environment in still air?

Hot air rises.
