Bongs and Pipes (DIY)

[Bdan3us]

Well the other day i created a bong out of a Propel water bottle. originally it was just a bong but i decided to add a tube for sucking at the top. eventually i cut the tube in half and put it in their too. So the final result was a bong with 2 tubes at the top for sucking. it worked quite well, except for the fact that i didnt have a real slider so i used a metal pen cap. Which eventually melted. So now im working on a bigger bottle with the tubes again and a metal pipe at the bottom. But i have purchased a glass slider to put in the metal pipe. Now im working on a, Gravity bong? i have no idea what it is, SWIM told me about it and i want one really bad. Can someone please explain via pics or blueprints of some sort. he wants me to build it for him. so any help is wonderful.
