In 1847, Joseph Fry discovered a way to mix some melted cacao butter back into defatted, or "Dutched," cocoa powder (along with sugar) to create a paste that could be pressed into a mold.

"For the purpose of teaching geography," John Spilsbury, a teacher in England, created the first jigsaw puzzle in the year 1767. Adhering his maps to flat hardwood, he used a fine saw to cut along the borders of the European countries, and the jigsaw puzzle was born. Hand-painted and made of wood, the puzzle was a map of England and Wales, with each county making up a separate piece. Soon, people began making pictorial jigsaw puzzles. Their purpose was to entertain rather than to teach. The pieces in these early puzzles were not interlocking. Not until the invention of power tools more than a century later did jigsaw puzzles with fully interlocking pieces come into being.

One day in 1849 Walter Hunt wanted to pay a fifteen-dollar debt to a friend. So he decided to invent something new. From a piece of brass wire about eight inches long, coiled at the center and shielded at one end, he made the first safety pin. He took out a patent on his invention, sold the rights to it for four hundred dollars, paid his friend back and had three hundred eighty-five dollars to spare. Then he watched his latest brainstorm go on to become a million dollar money earner for someone else.Visit for Fun :- http://jokesms-sashi.blogspot.com/
Police Officer William L. Potts of Detroit, Michigan, decided to do something about the problem caused by the ever increasing number of automobiles on the streets. What he had in mind was figuring out a way to adapt railroad signals for street use. Potts used red, amber, and green railroad lights and about thirty-seven dollars worth of wire and electrical controls to make the world’s first 4-way three color traffic light.
