i did that once, it kinda worked. well it worked the 4th try. lemme start off by saying u need a lot of patience. i sat on my carpeted floor and sat 'butterfly style' and held the bottle (opening pointing away from me) in between my feet (with some shoes on ofcourse) then i took a screwdriver bit and held it on the glass with some plyers. i then proceeded to hit the metal bit with a hammer numerous times, taking breaks to dip the bit in oil and water. remember do NOT hit the bit too hard, the bottle WILL shatter. also once u have a small hole or even a deep chip u can then take a sharp knife and twist it around in the hole to widen it. when u 'widen' it u will be chipping away at it. and dont get discouraged if the bottle shatters, it took me 4 tries, but it was worth it =D any questions boys n girls?
