Interesting fact of the day. Water will "catch fire" when used on anything over about 2,200 C.

You can observe this if you take red hot metal and dip it in water, you will see flames produced and even explosions.

The reason is because at those temperatures the water disassociates and hydrogen and oxygen is produced that then reignites turning back into water and producing flame.

In fact particularly hot fires can not be extinguished with water as the water will convert into hydrogen so quickly it will literally just cause an explosion.
