someone a while ago posted about there idea of using a gravity bong made out of a 2 liter to have another chamber to filter the smoke with water. what you do is this:

- take your first 2 liter's cap and make a bowl out of that and screw it back on the 2 liter

- than cut the bottom of the 2 liter

- now take a plastic bag and fit it around the bottom of the 2 liter

- now take some strong tape and tape around this bag so its air tight

- you now have the first chamber done

PART II

- now find another 2 liter with a normal cap that screws on and off

- now find some sort of tube, any length, and connect it from the first 2 liter to the second 2 liter

- make sure the end of the tube that goes into the second 2 liter is placed on the bottom area and enters the inside of the second 2 liter a couple inches

- make sure everything is air tight

- now fill the second 2 liter with water till its a little above the tube that you placed inside it

COMPLETE

- Now what you do is make sure the second 2 liter has its cap on at the moment

- now with the first 2 liter place some weed in the bowl that is on the top area

- now hold your liter on the bowl and pull bag back slowly to fill up the first 2 liter

- All you have to do now is unscrew the second 2 liters cap and inhale and enjoy

hope this encourages people to experiment

this is definently a step up from a normal gravity bong because now we can in take more smoke because its not hard on the lungs at all getting us higher!
