Spider webs on caffeine

So, I'm pretty sure everyone has heard of this already, but there was some work done to see the effects of drug exposure on a spider's ability to make webs. I couldn't find the original article, but here is a website about it.

They exposed spiders to different drugs (LSD, marijuana, caffeine...) and took pictures of the webs the spiders made. The caffeinated spider web came out very erratic. Here is a "healthy" web next to the caffeinated web:










Another interesting fact about caffeine is that it is an appetite suppressant. So, while the caffeinated spider web will most likely not catch anything, it's ok because the spider will not be hungry.

Too much of a good thing?

According to the book The World of Caffeine, by Bennett Weinberg and Bonnie Bealer, there is a condition called caffeine intoxication. This occurs with the consumption of more than 250 mg of caffeine at one time (more than 2-3 cups of brewed coffee).

The following are common signs of caffeine intoxication:
1) restlessness
2) nervousness
3) excitement
4) insomnia
5) flushed face
6) muscle twitching
7) rambling flow of thought and speech
8) tachycardia or cardiac arrhythmia
9) periods of inexhaustibility
10) psychomoter agitation

If you are not exhibiting 5 or more of these symptoms, it means you are not drinking enough coffee.
