Nope. Kids have been know to burst into flames and worse if they pick up a piece of steel. I read it on this site this one time.
It was funny having that discussion here of all places. The forum is about a sport that requires kids as young as 8 to throw weights and swing them as hard as they possibly can over and over and over but I was told, repeatedly and by more than 1 person, that allowing the same kids to pick up a weight and then put it back down was a real bad idea.
