Regular fire, i.e. wood or paper burning - no. Because there isn't enough oxygen to start or sustain regular combustion. But there are kinds of combustion which work underwater. Probably the best-known is magnesium. read more
Regular fire, i.e. wood or paper burning - no. Because there isn’t enough oxygen to start or sustain regular combustion. But there are kinds of combustion which work underwater. Probably the best-known is magnesium. You can light a strip of magnesium, and the combustion actually produces oxygen, which is then used to sustain the combustion. read more
Fire is a chemical reaction that releases energy (heat and light), nothing more. Most kinds need oxygen in gaseous form (air) to keep going, but some do not: magnesium burns just as well under water, because the reaction can sustain itself with water molecules just as well as with oxygen molecules in the air. read more
