The Electric Kool-Aid Acid Test is a 1968 nonfiction book by Tom Wolfe written in the New Journalism literary style. The book presents a firsthand account of the experiences of Ken Kesey and a group of psychedelic enthusiasts, known as the Merry Pranksters, who traveled across the United States in a colorfully-painted school bus they called Furthur. Kesey and the Pranksters became famous for their use of psychedelic drugs to achieve expansion of their consciousness. The book chronicles the Acid Tests and encounters with notable figures of the time, and describes Kesey's exile to Mexico and his arrests.
