well i've got this homemade bong thing, and where the bowl would be, its just a stem. and the stem sticks into the mouthpeice of my glass bowl. so its like a homemade bong using my glass bowl for the bowl. its great cuz its a healthy smoke, (using glass, instead of some metal wrench socket from the tool shed) but i also get to fill the bong with ice so it gets cooled down. and also you dont get a mouthfull of ash. Its the best way to smoke, in my oppinion
