you can hold fire on glass as long as you want, it won't fuckin melt, what are you thinking?

sorry about that kid man, the only perfect way is with a certain type of drill for glass, other than that the glass will most likely shatter. I'd reccomend you go out and buy a Sobe. Sobe bottles are made with a small notch in the bottom of the side which is extremely thin glass and you can make a perfect hole there with a screwdriver every time. then you can use it as a waterfall bong and get completely blitzed off a little weed.
maryjanehaze Reviewed by maryjanehaze on . Can you drill a hole in glass ? what is needed ? what type of drill bit ? I want to make my own bong , and I have a really nice piece of glassware i want to use , and then add my own bowl etc. Can this be done ? I practice drilled a Corona Beer bottle and it shattered just as i drilled through . :( Rating: 5
