Right now i use a homemade grav/waterfall bong and it works pretty good. The only thing i hate about it is you have to refill it after every hit. My friend owes me $50 and he said he could get me a bubbler instead of paying me the $50. I just want one so that i can have smooth hits but not having to refill it all the time. And i do not want something as bulky as a bong(although a bong would be pretty sweet). I hope my friend comes through and gets me the bubbler.
