I think someone on here mentioned the other day that they know how to make glasses from wine bottles. I have a mountain* of empty beer bottles, so I was inspired to research how to make them into drinking glasses. After 6 or 7 tries, I can't seem to break them cleanly, i.e. it's way too jagged to drink out of. What's the secret to getting a smooth edge suitable for a drinking vessel? I have a feeling my water isn't quite cold enough, but other than that I'm kind of lost. I'm following this tutorial: http://366daysofpinterest.com/2012/04/03/day…

*My girlfriend and I drink A LOT of beer, but there's no glass recycling where I live, and I don't have the heart to throw them all away.
