I've seen a friend of SWIMs that had a long pipe, so when it got really resinated he would scrape from where your mouth goes towards the bowl, and could get a good pile of crystals. When he had the pile inside the stem near the bowl, he would just get a straw or something to push it into the bowl. Then smoke it up of course. Also, SWIM
used to put his mouth on the hole on top of the bowl and suck out of that side. By this he means he would not scrape the pipe, but light the mouthpiece/as much of the stem as possible and it will start to smoke.
