    Old tread, but what the hell, I'm bored (for bored read should be working LOL), I prefer a proper glass cutter, preferably with a steadying rig, but for the odd times I've done things with this meathod, I've always found the thinner the string (with good fuel) works better, also don't use ice, the thermal shock can be way too much for the glass and it makes getting a straight break much harder, room tempratute water should be fine.

    can i ask? cause i love this kind of experiment what's the science behind this? curiosity kills and i would like to use this as my magical experiment :)

    My understanding is that it has to do with the glass being stressed. When you rapidly change the temperature of glass, it contracts and expands so quickly that it will shatter. You may have noticed this if you ever put a cold dish in the microwave and had it crack or shatter. Or Maybe you pulled a hot glass out of the dishwasher and put ice cold water into it and it cracked.

    This project works because you are concentrating the temperature change to a very specific part of the glass. If you were to heat up the entire bottle and then suddenly freeze it, the entire bottle would likely crack and shatter.

    I love how easy this trick is! Do you have any idea to preserve the label that comes with the beer bottle? The label is not really wash resistant as it is.

    That's a good question. Those stick-on paper labels don't really hold up well to water, especially if you want to put these in the dishwasher. Unfortunately I don't know how to keep those labels on there. Maybe there is some kind of clear-coat you can put on the bottle over the labels to sort of laminate it in place? It would likely have to be non-toxic and also dishwasher safe. I haven't ever looked into this so I'm not sure what's out there. Hopefully that will give you some keywords to start with though. Maybe another user has experience with this and can comment?
