its gotten a small facelift since last posting. I had a diffused glass on glass female (I still have the original somewhere) with like 13? holes, and found that it was then a liter bong as it took a full 32 oz of water to perfect the flow. But Im back to a non diffused female now cause it fits better. (for having such a large volume bubble, these things really aren't very deep. the female goes almost straight down about 4inches so its best hit vertical with as little tilt as you can manage) *edit im stoned and didnt finish before replying* with the original non diffused female style it takes a little less water. again, sorry for the shitty cellphone pictures and taking over a year to reply. buuuuuut whaaaaatever xD
