You can't burn water, because it's already burnt (lemmy.ml)

Fire is the rapid oxidation of a material. Water is 2 hydrogen and 1 oxygen. Every molecule is fully oxidized. It's also a common byproduct of fire. Therefore, you can't burn it, because it's already burnt

Honest question. Isn't the metal combusting at that point?

Both contribute to the combustion, but it's the metal that's fuelling it while water plays the role that air/oxygen usually would. I think codyslab did a video where he had a flame fed by air in an atmosphere of methane which demonstrates the concept that actually you need both fuel and oxidiser for the flame, and one "burns" in an "inert" atmosphere of the other
