haha years ago, back in my high school days I made 3 different bongs in my ceramics class. My first piece I made was a "vase" that held flowers out of the side of it. It held over 44 oz of water and on our lunch breaks we would go down to the local 7/11 and buy a big gulp of water and ice to fill it up. Man I miss that thing, it would fuck you up!!! I also made two others that my teacher said that I should put it in the school art show, but I never did for obvious reasons.
I also made a double perk out of 2, 1 gallon jugs of tree top apple juice containers, some flexible rubber tubing, a hot glue gun and a pen. I stored it in my friends basement and forgot about it. years later durring an inspection of the house my friends step dad and an inspector found it and didn't know what it was. Ahhhhh those were the days!!!
