The ghetto-est piece I use and have ever used is a Sobe waterfall, using a bowl I bought from one of the many many nearby headshops. All glass, no plastic or rubber or glue or anything to poison me.

Looking at that thing though, you're not gonna be able to get a lot of smoke into that thing, and once you do, you won't be able to easily get all the smoke back out without a carb of some sort. It's definitely worth it just to make a waterfall out of a Sobe bottle or something.
stick Reviewed by stick on . How good do "lungs" work? I've realized that I like trying out new smoking methods and I haven't tried out the lung so far. It's fairly easy to make one, in fact, I just made one from a 500ml Naya water bottle and a medium sized Ziplock bag. I'd like to know the following: 1. How efficient are they compared to a bong or GB? 2. Do they leave a strong smell? Comparable to a joint? Bong? 3. Your experiences with lungs. Rating: 5
