This really does work. I tried it so that I can cut all my bottles in half to start an indoor garden. The trick is in the thickness and how much the string can absorb. BTW acetone is also known as finger nail polish remover. I havent tried this with rubbing alcohol yet. The thicker the glass, the more wraps around the bottle you need. I tried it with regular yarn and it worked fine. I tried it with construction string (yellow) and it didnt seem to absorb enough acetone to even light.

A few words of wisdom: wear gloves, make sure the water is cold, wipe excess acetone off of the bottle. I first wrapped some string around the bottle, tied off a knot, then soaked it in acetone. The put it back on the bottle and wipe the glass off so the flames dont go crazy. Rotate the bottle constantly while the string is on fire, then dunk it in cold water. You do not need to apply very much pressure. One thing im not sure about is if you rotate the bottle until the acetone burns out, will the surrounding parts of the bottle near the string be just as hot, thus producing an unclean cut? or does a clean cut depend on a cold bottle with a small amount of heat in a confined area? (the string) i have a lot of bottles to practice with because I actually have a use for this, and I will post results on instructables.com soon. Thanks for posting this. Cheers!
