Introduction: Making a Cup From a Cut Beer Bottle
This is the natural successor to last week's video on how to cut a bottle with hot water. Here's how I got the raw edge on the cut glass to something that you could use for drinking out of. If you have a good, clean break you can actually get the rim to be perfectly level with minimal effort, and it looks really good. A lot of tutorials don't seem to put as much effort into the finishing part, because of how hard it is to sand/grind down the glass edge to a flat finish without a belt sander or something. My solution was (as my friend called it) a "power jig", construction shown in the video.
If you have extra glass that didn't fracture off cleanly, you can usually break it off without a problem. If your crack extends down into the cup, you'll either have to discard it or re-score the bottle lower for a shorter cup... or at that point, a mini-bowl. Maybe a dish for soy sauce when you have sushi...
As long as you polish out most of the cracks and chips (stress points), your cup should be relatively safe in the dishwasher. Go with the top rack though.
The bottle I used was for Woodchuck Hard Cider, scored and cut 4 inches from the base. It comfortable holds 1 cup of beverage, with about half an inch of clearance from the top.

Options for future variations:
1. Use a thicker bottle. Even with a rounded lip, it feels weird to drink from because we are all used to drinking from mugs with substantially thicker walls. If you frequently drink from shot glasses or plastic cups however, you'll be right at home.
2. Etch the bottle/cup for a unique, classier finish and look.
