Both are great bong making links. If you don't want to buy a bowl to stick in the top (probobly why you want to make one in the first place) you can "borrow" the top of a salt shaker from a restaurant and turn it upside down. Not sure on the saftey of the metal used to make it, but if you just set your lighter up to it for a while, it should burn all the really nasty chemicals off the top. Be sure tip well as you are ripping them off.
