all you have to do is go look about 1 and a half threads down on the aluminum part of the bulb, take some scissors and just go to town, the filliment will break off as you do this and probably fall into the lightbulb, so take that out and wash it out so all the little glass particles are out of it, the cap and straw thing is self explanitory

as for smoking it, heres what works the best... hold the lighter so that the flame does not hit the glass, the tip of the flame should be about a centimeter or two below the glass (this way, all of the impurities in the butane burn off before the heat hits the glass, so you dont get that caked on black shit), you may need to preheat the bulb for a couple second, but as soon as you see vapors keep the lighter right there while your inhaling very slowly, you will see the grey vapors come right off the weed and continue into your mouth, if the vapors turn into smoke, then just back off the lighter a little bit, you wont feel anything until you start to exhale, then you die. the end.
