Im using a homeade bong stem that I made out of a bic pen, a metal hitter, surgical tape, tubing, and a cut piece of rubber. I need a bowl so i can pack more bud into it. Whats the best way i can make a stem that will accomidate these needs?
i take it the rubber is for a seal? use a socket. a 1/4'' socket is pretty much a perfect 1 rip go bigger if you want to pack more just make sure the hole in the bottom isnt huge
