Dave is correct, you don't need a torch lighter, you just need a good hit that you hold in forever or until you have to cough. I got pissed up with some mates 2 weeks ago & we smoked 1g between 3 of us using a waterfall as we had no bong. I was pissing my pants laughing for I don't no how long & all of my friends were unzipping in long sections running down thier bodies, fucked up but very funny. I also felt like I was on a boat, It was really funny & I loved it.
I reckomend getting really drunk then taking a huge hit, but make sure you are not on a roof or balcony when you do it, & do make sure their are some watchers, we had some girl friends their that were not taking it so it was perfect.
Keep it Legal
