Clear PVC does exist. It's cheaper (2" of 4"clear acrylic plexiglass pipe was $70) than the clear acrylic plexiglass pipe I used in my bong. The only reason I didn't use the PVC is it won't bond to the acrylic plexiglass my case is made of. Most places that sell plexiglass should have the clear PVC. Also it seemed to have a slight yellowish tint to it.
