Me and my friend made this thing. It took our stoned asses 2 hours to make out of 3 2 liter Pepsi bottles, 1 poland spring water bottle, tape, bamboo skewers, and cardboard. The bowl came off some shitty broken bong my friend had. http://img205.imageshack.us/img205/1456/sspx0014.jpg http://img219.imageshack.us/img219/6953/sspx0009.jpg One bowl knocked me on my ass. 2 bowls just made me disfunctional . The thing is it takes a team of like 3 people to hit it effectively cuz there's so much air space inside. The hits are clean though.
should have made them out of sobe bottles. you can puncture a nice round hole at the bottom of a sobe bottle. im sure you could figure it out.
