i just made one out of a big glass orange juice bottle, with a glass bowl and downstem that cost me 4 bucks at San Diego and its sealed with hot glue and its perfectly airtight, i wrote a bunch of stuff on it like verses and shit with a sharpie its not quite as ghetto as most of the ones described and shown here but i think it still falls under the category of homemade cause it took me about a half an hour to bang a hole in that glass bottle with an awl(put duct tape around it so it wouldnt spider crack) and hit it with the awl to weaken the glass till it popped through, im still thinkin of a name ill post pics when i have a chance to tomorrow

later...peace
