Check out the gravity bong I made:
Made this thing from a 1 gallon jug of apple juice. I used a drill press to drill a 5/8" hole into the glass, where I fit a "quick connect" with 1/2 vinyl tubing. I made one of these out of a plastic jug, but the glass is way less ghetto and maybe even elegant, albeit much more difficult to drill into without cracking. The blue silicone ensures an air tight fit between the quick connect and the glass. The actual "combustion" occurs in a pneumatic air fitting (like what you'd take off an any impact wrench), which I MIG welded onto the jug's cap, and again lined it with silicone to ensure no leakage.
I'm looking for opinions and maybe even suggestions for improvement in future designs .
