What one sees as fire is the luminous part of the combustion process. The flame we see consists of fine burning particles (combustible matter + fine uncombustible matter like ash), all raised to high temperature on account of the heat of the chemical reaction. These particles are so hot (above 900'C) that they emit radiation which we call flame. The air that supports the combustion gets hot (but it does not give out luminous radiation), and hence it rises up or goes upwards, carrying the fine burning particles. This flame or fire is lighter than the surrounding air and that is why it goes up. Its weight is less than equal volume of cold air or it is lighter than air.

You can measure the amount of air fire uses during combustion, place a burning candle in a shallow dish filled with water. now put a long glass or a bottle over the candle so it sits in the water. The candle will go out, but before it does the water should rise as the air is used for combustion.

Fire is a chemical reaction, in other words: a process. You can't wiegh it any more than you can wiegh water turning into steam. You can weigh the THINGS that are on fire, but you can't weigh the fire itself.

I invented one however i lost the blue prints when the fire spread and now i can't remember the spark of genius that led me to it's creation
