For a good bowl look by the copper pipes in the hardware store. There should be adapters which change, say an 1/4" pipe to a 1/2". Puttin a screen in it is a good idea too.
SmokeyPotter Reviewed by SmokeyPotter on . Gravity Bongs I've never used one but my roomate did (had to get rid of it before anyone else had a chance-wasn't subtle). Basically it really seemed to zonk him-he was getting flashbacks off shroom trips and the like-who has used one and are they any good? Rating: 5
