I’m reading Matthew Walker’s book Why We Sleep and came across this study which I found pretty wild:
In the 1908’s NASA scientists exposed spiders to different drugs andd then observed the webs that they constructed. Those drugs included LSD, speed (amphetamine), marijuana, and acaffeine. The results, which speak for themsleves, can be observed in figure 3. The researchers noted how strinkingly incapabable the spiders were in constructing anything resembling a normal or logical web that would be of any functional use when given caffeine, even relative to other potent drugs tested.
It is worth pointing out that caffeine is a stimulant drug. Caffeine is also the only addicitve substance that we readliy give to our children and teens-the consequences of which we will return to later in this bookR. Noever, J.Cronise, and R. A. Relwani, “Using spider-web patterns to determine toxicity,” NASA Tech Briefs 19, no.4 (1995(: 82; and Peter N. Witt and Jerome S. Rovner, Spider Communication: Mechanisms and Ecological Significance (Princeton University Press, 1982)
