it covers the flame, therefore not allowing any oxygen to reach the flame.
The color of the flame depends on the metal from the salt.

Well mainly pressure against the flame WHEN YOU BLOW IT: Well when you put air pressure aginst the flame it causes it to go out PUT SOMETHING ON TOP: Well when you put somehting on top(such as a metal candle burner) it puts pressure against the flame...it aventually burns out
It is never put it out. It burns forever because it is symbolic.
Fire requires oxygen to burn. No oxygen = no flame. When you put a flame in a jar it lives off the oxygen inside the jar for a while. Once you put a lid on the jar, eventually the jar will run out of oxygen and the flame will burn out.
