I make bong converters from things I get at home depot. I wrote a reply to someones thread like a week ago about it. $5 gets you all you need to turn any standard waterbottle into a bong! I can fit it into a sandwich bag and it doesn't smell that way, except for when I take it out, I have to take it out outside because I have smoked alot of reefer in it and never really cleaned it too good.
