yeah, i kinda want one of those, but im not too sure about it, it seems like a good idea, but after a while it would be a pain to have to smoke as much as you would have to, after all it isnt a small bowl, there has to be some amount to put into it that would hold it there. And if you have enough for a glass blunt, just roll a blunt and then stop smoking halfway through, or whenever you get tired of it, it will save, and you'll get higher than you expect when you relight it.
