what is the origin of the term acid test
Lysergic acid diethylamide By the mid-1960s, the youth countercultures in California, particularly in San Francisco, had adopted the use of hallucinogenic drugs, with the first major underground LSD factory established by Owsley Stanley.[111] From 1964, the Merry Pranksters, a loose group that developed around novelist Ken Kesey, sponsored the Acid Tests, a series of events primarily staged in or near San Francisco, involving the taking of LSD (supplied by Stanley), accompanied by light shows, film projection and discordant, improvised music known as the psychedelic symphony.[112][113] The Pranksters helped popularize LSD use, through their road trips across America in a psychedelically-decorated converted school bus, which involved distributing the drug and meeting with major figures of the beat movement, and through publications about their activities such as Tom Wolfe's The Electric Kool-Aid Acid Test (1968).[114] In both music and art, the influence of LSD was soon being more widely seen and heard thanks to the bands that participated in the Acid Tests and related events, including the Grateful Dead, Jefferson Airplane and Big Brother and the Holding Company, and through the inventive poster and album art of San Francisco-based artists like Rick Griffin, Victor Moscoso, Bonnie MacLean, Stanley Mouse & Alton Kelley, and Wes Wilson, meant to evoke the visual experience of an LSD trip.
Pregnancy test Organon International obtained the first patent on a home pregnancy test in 1969, two years after product designer Margaret Crane noticed that the laboratory testing procedure was relatively simple and made a prototype. The product became available in Canada in 1971, and the United States in 1977, after delays caused by concerns over sexual morality and the ability of women to perform test and cope with the results without a doctor.[21]
