My only piece (a bowl that lasted 2 years) finally broke the other night. I was tired of waiting for my new piece to come in and last night I built the easiest perc I've ever seen. If it hasn't been done before I want it to be called an "Olive Perc" hahaha. List of Materials: 2 2-Liter Bottles (Light Green and Blue in the picture) Powerade Bottle (Red) Aluminum Can (Black, structural design and not used to smoke) Glass Bowl/Downstem (Dark Red) Cut one of the 2-liter bottles near the top where the flat sides start bending in, you will use both pieces. Take a soda can, cut the top off of it and cut notches all over it. Set the can inside the bottom of the cut 2-Liter bottle. On mine I made the downstem come inside the can, it doesn't have to. The only thing the can does is hold up the perc body. Cut off the bottom of a Powerade bottle and place it on top of the soda can. Now take the top you cut off the 2-Liter bottle and put it back on upside-down the bottom of the bottle. Cut the top off the other 2-Liter and place inside. It actually works fantastically well and only had to tape the original 2-Liter back together. Everything else was air-tight enough to provide a deep hit. It works like an upside-down dome perc now that I think about it... still it's really cool and super easy to make. EDIT: I would post pictures of the one I built but I left the labels on the whole thing.... you can't really see what's going on inside
