Pyramid power
Pyramid power refers to the supposed paranormal properties of the ancient Egyptian pyramids and objects of similar shape. With this power, model pyramids are imagined to preserve foods, sharpen or maintain the sharpness of razor blades, improve health (some people report having been "so energized that they could not cope with the dynamo effects they experienced"), function "as a thought-form incubator," trigger sexual urges, and cause other dramatic effects.
Pyramid power is one of many pseudoscientific theories regarding pyramids. Such theories are collectively referred to as pyramidology.
History
A French hardware-store owner and pendulum-dowsing author, Antoine Bovis, developed the idea that small models of pyramids can preserve food in the 1930s. Unverifiable stories persist that Bovis stumbled across a paranormal force while standing inside the King's Chamber of the Great Pyramid in Egypt. According to this legend, he saw a garbage can inside the chamber which had been piled with dead animals that had wandered into the structure. Bovis noticed that these small carcasses were not decaying, and inferred that the structure somehow preserved them.
