19. The lamp which cast darkness, April 1, 1955
Popular Electronics published their April issue for 1955 including an article which described the concept of “Contra-Polar Energy”. Contra-polar energy was described as negative energy, which when applied to any electronic or electrical device would cause it to produce the exact opposite of what it was designed to produce. In other words, if applied to a light bulb, the bulb would cast darkness rather than light. An electric element on a stove would become ice cold rather than generate heat. The energy could act as a brake on an electric motor. According to the magazine the energy was developed secretly by the military during the Second World War.
The magazine included a photograph which depicted a table lamp creating darkness on the surface on which it rested. The article also contained a disclaimer, which directed the readers’ attention to the fact of its being published on the first day of April. Nonetheless, interested readers continued to write to the magazine for additional information for years. In 1959 Popular Electronics was forced to issue a statement which indicated the article had been an April Fools’ Day joke, and continued demand for more information led to their doing so again in 1963, eight years after its original publication.
