They were lots of fun when you took a whole roll and dropped a rock on it. Right up to the point where someone got a piece of the rock embedded in his @$$.
Of course you realize that those fun caps are probably banned by the child safety nuts. Makes me wonder how so many of us survived all the fun stuff back when we were kids.
That's probably the first time I got my ears to ring but I was using my dads hammer. Ear plugs Gents ear plugs. Yeah fun stuff, I could'nt even begin to remember how many trees I've fell out of, nasty ponds I've swam in all in the pursuit of frogs,newts and snakes or how many times the neighbourhood was out looking for me/us because we managed to get lost in the woods and all the belts and switches that came to me because of it.
