I think we've smoked out of just about everything, lol...my husband has always made homemade pipes/bongs, etc...and they have always been really good and gotten great reviews from fellow smokers, lol. Actually, he made one exactly like the one in the picture above -- his fav. to make is like a gravity bong with a 2 liter bottle and a bread bag - the bowl being on top of the lid of the 2 liter. We have our fair share of boughten pipes/bongs including glass - we use'em all....but we have most fun with the homemade ones I think, lol.
