psychoactive substances and the behavior of several spiders

Once, in order to test the effects of psychoactive substances on the behavior of living things, NASA doped-up several spiders and watched them build. What resulted were some undeniably trippy web patterns. Now, one designer has replicated those drug-inspired creations into some unique-looking bowls, sure to leave you a bit dazed and confused.
During the testing, several spiders were given doses from one of four different substances: marijuana, benzedrine, caffeine or chloral hydrate. Interestingly, the web patterns the intoxicated spiders then produced seemed to reflect their altered state, deviating significantly from their standard web design.
