I cant quite picture it...Im too easily confused.
anyhow, I just took a water bottle, put a little hole on the side towards the bottom, stuck a pen in it(with the ink thingy taken out, so its hollow)on the other end of the pen, I stuck the bottle cap with a hole in the bottom. Add water and tinfoil, and ya got a cheapo bong. For a pipe, one of my friends took a mini flashlight, took everything out of it, except the part where the bulb rested, and I dont think he even used any tinfoil for the bowl. It was kinda cool. er..kinda.
