After you get the resin out, it works well to put a few cigarette or pot ashes in the bowl and put the resin on top of the ashes to smoke it. It melts so the ashes keep it from dripping straight down the bowl again before it can burn. A piece of coathanger is usually close to the size of the hole in metal pipes. If you can take the pipe apart that works best. If not then you have to push the resin through the pipe backwards, back into the bowl. Then you can dig it out with knife or something.
