Id have to say, knife hits are the most efficient. On that note, did you know you can make an inhaler for knife hits with a glass bottle? just drop in a butterknife, cover the hole with your thumb and shake downward until the bottom drops out. takes a few to get the hang of it, but its awesome
if what you mean, youre trying to remove the bottom of a glass bottle, let me shate my knowledge. get some rather thick string, i use a shirt that i stripped into a long line of thread. tie that close to the bottom of the bottle, soak it in rubbing alcohol (the highest% you can find) light it on fire, let it burn for about 60-75 seconds. then dunk it in some water. the pressure and rapid temp change, causes the bottom to simply pop right off
Wowza! Right on dude, that sounds like fun. I like my smashy method, without all the fire and explosives, and water goin everywhere. I get a nice round and even break, usually with a single downward thrust. hehe. Can even use a bolt, or anything small and heavy you could fit in there.
