i try not to scrap my pipes as much as possible befcasue i turn to the resin when i've been dry for awhile, but i just got a new bong so i stuck about a bowls worth of weed into the pipe shook it around and began the pain staking task of getting it all back out with a paper clip (i don't mind, but it is tedious work none the less) ...broke in my new bong with some decent weed soaked up in resiny goodness (not the hard resin that normally forms in my pipes either, it was the good shit that is pure liquid and has a yellowish brown tint to it)
