it's easy, but you need either a set of bubble bags or a piece of silk screen material...i use silk screen material. i buy a chunk of dry ice, smash it up in the heavy plastic bag it comes in, then pour it and my trim/popcorn into the middle of the piece of silk screen material, make a bag out of it, and shake the shit out of it in a 5 gallon bucket (well cleaned)...the trich heads fall through, and the plant material stays in the bag. you stop after 3 or 4 minutes and collect what's in the bucket, kief. (what's in that jar ^). then you do it again till you start getting greener looking kief, which means it's about played out. i'll shake it a couple more times, but i keep that greener kief separately, and use it to dust bowls, or make moonrocks... you can cook whats left for butter, or just get rid of it. you can keep the kief sealed up like that for quite a while if you let it dry a little, or you can keep it frozen "fresh" and use it as you take it out of the freezer. you can take the kief and make hash. i use the hand method just kneading it for a long period of time, letting the warmth from my hands help "melt" it. a bottle full of hot water helps as a "rolling pin", i've been told, going to try it myself the next time i make some. you can also use a press, but i've found that the small hand units don't make it melt inside, you need a hydraulic press to get enough pressure to make it "blend".
