Revealed is the easiest, tastiest way to make hash oil. All you need is some sort of a plastic tube, where you poke one small hole in the top and several small holes in the bottom which you line with 3 layers of coffee filters cut into circles. Then take about an ounce of weed into it. Then dump some butane in and let it sit till it evaporates. Finally just scrape out all your leftovers and then you have some tasty hash oil to put on your blunt or cigarette. This stuff is strong so just put on a little at a time.
