Primary Perception

Cleve Backster was one of the top lie-detector operators in the world. He taught FBI, CIA and other agencies' operators on the use of the lie detector. Quite by accident, he discovered that plants responded to events and thoughts in their immediate environment. This book is written by him, explaining what he did, and the results. He spent decades researching things like what happens to the eggs in a carton when one of them is put in boiling water. Or how a plant in the room responds to putting eggs in boiling water. He noticed the plants reacted when men's urine, in the other side of the laboratory wall, were killed by antiseptics in the urinal.
