yeah...Nnnnot 8th grade, I agree. I used it, though, with college (mostly) sophomores in an intro diversity course when I got to arachnids--totally set it up with spinneret anatomy & silk chemistry, then the real* research on drugged spiders' webs. It was great.
*yeah, it's NS. article ref: Noever, R., J. Cronise, and R. A. Relwani. 1995. Using spider-web patterns to determine toxicity. NASA Tech Briefs 19(4):82
Okay, I used to have those Time-Life books when I was a kid, and one of the books had pictures of such webs, and I remember the LSD web was really symmetrical and didn't look "impaired" at all. And yeah, the caffeine web was the worst.
