Ok, the idea, I think, is to hollow out a light bulb and basically stick a pen on the end to inhale it. So what I did was literally saw the black part of the light bulb off with a hand saw. Then I ripped the actual light bulb part out so that it was all glass and metal. Then depending on what light bulb you use, dump salt in and mix it around to get the white stuff off. Then put two holes in a bottle cap, one for the choke and one for the plastic part of a pen. Then cut the top of the bottle off and make cuts down it so that when you tape it the plastic is flush with the bulb. So then tape it up really good, below the cap part so you can unscrew it and reuse it.

Then dump, light, and inhale. Keep in my mind this is all coming from the guy who couldn't get it to work though, so if someone wants to correct me be my guest...
