I smoke out of my zong with ice, or my piece which has been hiking with me everywhere (too lazy to take a pic, it's just a thick glass color changing piece, so tough it landed on rock in yosemite and didn't even break!)
Blunts, Bongs, Pipes, Joints, Steamrollers, bubblers, chelums, gravitys, vaporizer, knife rips, skillits... i think that's it haha. I love variety. I personally own About ten different pieces, but my best homie who i grow with has at least 50 different pieces, his passion is collecting glass works. BLAZE KUSH
This be my main bong. An 18 inch green skull GEAR bong. Buddy of mine got it for 80 bucks flat. Not sure how thick the glass is; but its definately strong.
It's no ROOR but its a got a nice ice catcher beneath the skull which makes for an excellent ice hit.
Also, not sure if anyone will believe me or care but the circumference around the bottom (the beaker-like chamber) is the exact same as the height. 18''
