not a torch lighter....just a plain damn torch....and for me it takes maybe like 10 or 15 minutes to get the glass hot enough to puncture it....the key to doing this is take it slow....and make sure you keep the rest of the bottle warm while doing it....otherwise i always end up with explosively shattering bottles (not fun when a million fukin peice of shit lil shards go flying all over your skin while they're still 300+ degrees lol) after about 50 bottles i finally managed to get a couple with holes....if you have any tips i'd be overly grateful....
