I want to cut a bottle.
I've spoken to people who used the alcohol/string technique, and read stuff on the internet about it, but cannot get it to work.
The descriptions of how to do it are vague at best when it comes to how much string to use, or what type, and how saturated it must be.
How are you supposed to hold the bottle when it's burning? How long it should this burning process take? Is a gentle blue flame (with alcohol) too weak, do I need a raging inferno?
