In 1943, architect Richard James was attempting to build up a spring that would bolster and balance out delicate hardware on boats. When one of the springs incidentally tumbled off a rack, it kept moving, and James got the thought for a toy. His better half Betty concocted the name, and when the Slinky made its presentation in late 1945, James sold 400 of the fun toys in an hour and a half. Today, in excess of 500 million Slinkys have been distributed around the globe.

4. Potato Chips
George Crum is the responsible person if you ever wanna thank you someone for loving potato chips. Discovery of potato chips is really interesting. George apparently made the salty nibble in 1853 at Moon's Lake House of New York. He then tired of a client who constantly sent his broiled potatoes back complaining that they were spongy and not crunchy enough. Then George cut those potatoes as dainty as could reasonably be expected, seared them in hot oil, at that point drenched them with salt. The client adored them and "Saratoga Chips" rapidly turned into a well-known thing at the cabin and all through New England.
