Are Plants Watching Us?

This fascinating short documentary reveals the work of scientist Cleve Backster, who investigated plants’ “secret lives.” Backster argues that plants are sentient beings, despite their lack of a nervous system; we are merely unable to detect the fact that they are conscious. He attempts to show plants' awareness by hooking garden-variety ones up to a polygraph. The machine records spikes in electrical activity which seem to correspond to Backster's actions. It even jumps when he focuses his mind on a mental image of a burning fire; it seems that the plants could sense Backster’s presence and even his emotions.
