using a a torch with map gas or propane will work to melt the glass. But I used to make bongs out of liqour bottles, I bought a bit designed for drilling in to glass at homedepot. It was like 13$, and yes keep water on the bit and where your drilling and it should work fine...
HeyItsMe Reviewed by HeyItsMe 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
