The Electric Kool-Aid Acid test and graduation.

Mountain Girl returns home because she's pregnant, probably with Kesey's child, and another member has neautological problems from his intense drug use. Kesey spends the night in a graveyard and comes up with the idea for the acid test. The test will be about energy and even though it doesn't reach out to the whole world, it has a good start. The begin advertising their acid test at a rolling stones concert. Kesey talks to the man from before who is in the Grateful Dead and the band agrees to play at this acid test party the pranksters are throwing. They throw it on a beach, after changing locations once, and reveal their new toy, STROBE LIGHTS. Everyone has taken LSD including Owlsey, the man in the band, whom no body has every seen trip. Owlsey has one of the most remembered, bad trips nad will be talked about for years to come. Kesey puts on the biggest acid test ever at a stadium but of course, the cops shut it down. The police try to arrest all of the pranksters but their attorneys bail them out. Kesey gets three years porbation and a little service work but he is off the radar. When someone calls the cops on the group for being rowdy they come into Kesey's home and find that he had merijuana in his possesion and this begins most of Kesy's legal troubles all over again. He is not supposed to go to the Trips Festival they've been planning and he is not supposed to hang out with the Merry Pranksters anymore but of course, he can't bail on this. The Festival lasts three days and begins to be a weekly thing. Wolfe says 'the Haight-Ashbury era began that weekend'.
Kesey is forced to move and has a warrant out for his arrest so he moves in with Babb's to his home. The Pranksters help fake his suicide while they smuggle him into mexico where he'll become an outlaw.

I'm not going to spoil the ending of the book, and a lot of things happen, but if this interests you at all, I highly reccommend reading it! Just be sure you have no distractions because it's a bit hard to follow.
