Im not sure if anyone has Made a thread on this before or not but here goes. Also if this is in the wrong section could a mod please move it. How to make a glass gravity bong or lung: 1: Put a nail or butter knife in a beer bottle 2: hold the bottle over a bucket or garbage bag (something to catch the glass in) 3: put the palm of your hand over the mouth of the bottle, and give it a quick shake. If you did it right the bottles bottom should come right off without cracking the rest of the bottle. Be careful however as the bottles bottom may have jagged edges that will cut you. It is advised that you take a nail file or sand paper and smooth out the glass. Now just make a gravity bong the same as you normally would, except this time it's glass, so it's naturally more healthy and easier to clean. For the bowl I use a glass bowl and stem from a bong, but you could just put a bottle cap back on the bottle and poke holes in it. Diagram for a G-Bong:

This seems easier, and I would use a wine bottle. [ame=http://www.youtube.com/watch?v=cU0X6sgc4_0]Cut Glass Bottle in Half - YouTube[/ame]

I agree with using a bigger bottle, I just haven't tested it with anything larger than a Perrier bottle.
