If you ever need to cut a glass bottle, here’s a great guide on how to do it.
Simply take spool of threads, tie it around where you want to make a cut, apply some lighter fluid, then light the thing on fire.
After the fire burns off most of the thread, put it in cold water and wala, you have a perfectly cut glass bottle.
I’ve had many times where I could have used this trick, great to know.
