That is crazy the water put it out. Typically magnesium burns hot enough to separate the hydrogen and oxygen from the water making it far worse/explosive! Lucky
Was a Combat Engineer in a previous life, can tell you that lighting magnesium isn’t easy unless it’s in the form of shavings or powder in which case it’s almost like gunpowder. Never tried to put it out once we got it lit but we were told to try and cut off the oxygen source with mud if we needed to put it out. Once it’s going it’s scary stuff.
