It took me several tries to get this glass cutting down, and my cuts are still jagged. If you're looking for a cleaner cut, try the boiling water method, or perhaps try using a dremel tool.
Recycled wine bottles
Bucket of COLD water
Matches or lighter
Be careful. There is an obvious burn risk with this project. Be sure to wear goggles and gloves. In any case, here's the tutorial.
- Fill bucket with cold water.
- Soak the string in acetone and wrap it around the bottle several times.
- Light the string on fire and rotate the bottle so that all sides are heated evenly.
- When the acetone is about to burn out, place the bottle in the water. It should split where your string was.
- Sand down rough edges.
