A friend of the family was sitting around their fire pit and their pre-teen son was being a kid poking the fire. Unbeknownst to parents he was using an old golf club to poke it(I'm guessing an iron?). Out of nowhere the club exploded in his hand and put him in the hospital with burns and other trauma. He has some pretty severe burns, but will be okay. Obviously the moral of the story is don't use clubs as fire pokers, and pay attention to what your kids are doing. However, what would make a club explode when exposed to fire? The only thing I can imagine would be magnesium??
