Stemmed gravity bongs combine the advantages of gravity and standard bongs as well as giving a significant use for water as opposed to a lung. One of my personal favorites if I don't need to worry about hiding the thing.

Invention?? ok i dont know if this has been made already or not SO DONT FLAME AT ME!! but what i did was i took a 2 liter bottle, cut off the bottom and put a bowl on the cap... simple gravity bong right.. but the bowl had a rubber tube that went into the water... so when you pulled the whole thing up the smoke went under water and then got trapped by the bottle... pretty fucking sick Rating: 5
