A warning to all those who shake b.b s and water to get out the initial bad stuff - I just put a hole in the shoulder of a rare drug store bottle doing this. This method has GENERALLY worked well in the past,but every once in a while you get a bottle with thin glass around the shoulder - this is the third time this has happened over the years - I still think its a fairly good method,but you should add some detergent(which I didnt do today)for a little "cushion" and dont shake TOO hard.
