Even for soft glass (non-pyrex), one needs at least a MAPP gas torch. Supposing a butane torch actually could, you then have to evenly heat the glass to a uniform temperature, then let it cool SLOWLY, in a kiln, in order for the entire piece to cool at the same rate. Otherwise, it will shatter. In fact, it will shatter if you just apply heat to one single part while the rest remains cool. Also... if you WERE to get the glass hot enough.. then to suck IN.. you'd very much likely burn the fuck outta your lungs. This is why glass blowing tubes have backflow valves.. the superheated air inside the glass can create fatal situations. Also, simply heating the desired spot to the correct temperature point creates the hole, no air in the tube required. Blowing is only for expanding the glass, and some very special techniques that I can't remember offhand. Any other shaping is done using graphite tools. If you want this done, and don't have cash for a glass bit, I'd suggest the old aquarium modifier's glass cutting method: take a copper pipe, cut cotches in one end, fit the other end to a drill. Create a reservoir around the spot to be drilled, fill it with water and medium grit rock tumbler powder, then weight the lowering arm of your drill press by slowly filling a gallon water jug until it applies light, constant pressure. Takes about 5-15 minutes to cut medium thickness glass. On the other hand, you can also just put a rubber stopper in the top, with a downstem and a hose run through it, and make it a shoddy hookah. Oh.. and don't ever use epoxy to affix your downstem. If you can't find rubber grommets anywhere, 1. you're an idiot, they're about $2 for a 5 pack at any online headshop, and 2. use aquarium grade silicon caulk, available at any fucking hardware store, ever.

As aside note, it's amazing what some people will tell you just because they ASSUME it will work.
