Here's a quick video showing how to cut a bottle with only a bottle cutter and a candle. 

There's no need for water, ice, chemicals, etc. Just a means for stressing the glass.

Also, check out the place I got the cutting jig from -

There's quite a bit there on alternative energy. Pretty good stuff. 

Now I can start making more complex vacuum tubes without trying to build them like a ship in a bottle. XD XD

And remember, if there are ANY cracks in the glass after cutting it: It's no good - Throw it out. Because under pressure or any form of strain, these will grow and eventually shatter the bottle, and that's definitely not a fun thing to have happen.

Thanks again for watching and stay tuned.
