Sorry man, been done.

Does it work real well though? I'm real tempted to try it, but with the grav top I'm using it'd be difficult and I don't know what I would use as the stem. I'd need to find some other stuff to use.

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
