I have made a "double bubble" water pipe. Most people that has been around my house or where I have taken it really enjoyed the pipe. I have made a few for people and been asked to make more. I use recycled parts from old broken pipes and make the double bubble. Parts can be purchased and I can have it built for you.
Another Item that has been ask for frequently is a stalk pipe. "Stalk Pipe" is a walking stick / smoke pipe made from marijuana plant stalk.
