We've been using wooden skewers for s'mores, which has been fine for everyone but one kid. And, you just need the one. The one kid never ceases to let the stick catch fire, and then wait too long to put it out, and then panic and do all the wrong things. It was an accident waiting to happen.
So we went big time and got the steel extending skewers. They allowed everyone to stay far, which was good. They made it hard to blow out a fire on the marshmallow, partially because they were fully extended. When you pulled it back, the marshmallow would be over your head. Not only can breath not reach to blow, but firey marshmallows in the air are bad. The other con is that the boys thought they were weapons and when not paying attention almost poked some eyes out.
All issues were human error and hopefully we will learn to use these without injury. Only time will tell.
