This is the piece that stays at my girlfriend's place... Just snapped this pic now... kinda dark... it's a two-chamber water bong. Lower chamber feeds up into the "neck" of the bong, which holds another small water reservoir. I tend to like the "slowly burn a whole bowl and kill it in one hit" kind of bong hits... but because of the double chamber thing, this bong gets smoke into your mouth/throat/lungs before you're done burning through the bowl. As long as you don't wait to long to pull out the bowl and kill the hit, it's smooth as hell. But it will send me into a coughing fit if I try to be a tough guy and kill a whole bowl in one go.
Got a few more at my place, but no pics. I'm a devoted bong guy though... probably about 90% of my smoking is bongs. Blunts are great for parties/groups. Vaporizers are too expensive/fussy/whatever. I do really enjoy a good bubbler though... and seing the ones above makes me want to get one... lol
I'm gonna to pack a bowl in honour of this thread!
