Yeah, definitely been done before, but still congrats on thinking of it yourself. That way the smoke actually gets filtered, probably a gravity bong like that gives the best hits IMHO.

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
