get a pair of pliers, pull off the end that you would typically stick the cap on when using the marker.
Lol is their a technique to drilling threw glass with reg bits...i already broke 2 bits but I think its from pushing down to hard.
Nahh that dude is wrong i filled my bottle with sand and then poured water on the bit and bottle every few 15 seconds or so to keep it cool and it didnt shatter.just go slow bro
No offense but have you ever smoked weed before do you even know what a bong is! If so how is it suposed to get filtered by the water if it's not touching it? Maybe you should find put what a bong is or smoke a real one before you make one. And if it's your first time don't do it out of a bong. Your gonna choke like shit.
