I would agree that homemade bongs 90% of the time are no good. I like smoking good weed and I like smoking out of interesting stuff. I don't mind joints/blunts if they are rolled well. To me if I'm going to smoke, I'm going to do it up right. Like I said though, everyone once in a while a homemade bong is worth while. Grav bongs are usually worth while, just because they will drop you. Someone who takes cosmetics into account for homemade bongs usually will have a worthwhile bong. The beer bottle bongs I've seen are pretty cool as well. They certainly aren't a 5 min job though.
