I was surprised by the number of people who wrote me and offered different versions of the cigarette tar collection system used in the Science Fair project. It was interesting to read them and remember back to those dinosaur days. That project was actually run in my school (no, not by me) and the system discussed will work. Suck a few cartons through it and you get a measurable mass of tar in the cotton balls, and it looks just god-awful! The guy who did it even took some of the tar and rubbed it on a lab mouse, which a few days later developed cancer and died. Pretty damn gruesome! On the other hand, he pretty much dorked around with it, collecting the tar in the cotton filter, but not weighing it or analyzing it. Any of the systems mentioned to me, such as water traps and more efficient cooling mechanisms, would work. I spent the better part of ten years as an industrial chemist, and I still find it interesting.
The other thing that is starting now is that Carl is getting frisky. Sex will never be the prime focus of the story, but it is an element, and it was written for an adult site. This is one of the big differences between the StoriesOnline version and the StoryRoom version. This version is the PG-13 version.
