The # 1 April Fools Prank of All Time - The Swiss Spaghetti Harvest

April 1, 1957: The respected BBC news show Panorama announced that thanks to a very mild winter and the virtual elimination of the dreaded spaghetti weevil, Swiss farmers were enjoying a bumper spaghetti crop.

It accompanied this announcement with footage of Swiss peasants pulling strands of spaghetti down from trees. Huge numbers of viewers were taken in.

Many called the BBC wanting to know how they could grow their own spaghetti tree. To this the BBC diplomatically replied, 'place a sprig of spaghetti in a tin of tomato sauce and hope for the best.'

Even the director-general of the BBC later admitted that after seeing the show he checked in an encyclopedia to find out if that was how spaghetti actually grew (but the encyclopedia had no information on the topic).

The broadcast remains, by far, the most popular and widely acclaimed April Fool's Day hoax ever, making it an easy pick for number one. #1: The Swiss Spaghetti Harvest

Spectrophotometer

In 1935, the first U.S. patent for a spectrophotometer was issued to Professor Arthur Cobb Hardy of Wellesley, Mass. (No. 1,987,441) which he called a “photometric apparatus.”It could detect two million different shades of colour and make a permanent record chart of the results. The patent was assigned to the General Electric Company of Schenectady, N.Y. which sold the first machine on 24 May 1935. It used a photo-electric device to receive light alternately from a sample and from a standard for comparison. It eliminated any need for the two beams (from sample and from standard) to travel different optical paths which in previous designs could introduce inaccuracies if one path varied from the other.«[Image: a "GE-Hardy" double-beam recording spectrophotometer photographed in 1938 showing Walt Disney with the instrument at his studios.]
