Oh, so many pranks planned for today! I can't wait to get started. Here's a classic one from 1976. Man, people are gullible.
Today is April Fools' Day, the day for pranks and hoaxes. One such famous April Fools' Day hoax was the so-called "Jupiter Effect" of 1976. During an interview on BBC Radio 2, British astronomer Patrick Moore announced that a very rare planetary event was about to take place—that Jupiter and Pluto would soon align in relation to Earth, and their combined gravitational pull would momentarily override Earth's own gravity and make people weigh less. He called it the Jovian-Plutonian Gravitational Effect, and said that if people jumped in the air at exactly 9:47 a.m., they would experience a floating sensation. Moore signaled, "Jump now!" over the airwaves, and within minutes the BBC switchboard was flooded with calls from people who claimed it had worked.
