10 Simple Inventions which yielded Millions

The simplest ideas are often the best. In addition, they can bring tons of money. Remember the "Slinky", also known as the stair carpet, who would have thought that a simple metal spring as a toy would be so popular? Or even easier, the Frisbee, a simple round plastic disk. The following ten simple ideas are all "accidentally" invented and the inventors are making millions from it.

10 Frisbee

Walter Frederick Morrison invented the Frisbee in 1948. He got the idea when he and his girlfriend tossed a lid of a tin of popcorn to pass the time. He called his product the "flying-saucer" and later the "Pluto Platter". In 1957, the idea was bought by Wham-O who put the product on the market in 1958 as the Frisbee. The name is a reference to the bakery "Frisbee Pie". The aluminum cake pans of this store were used by students to frisbee. The inventor of the Frisbee had half a million dollars in royalties in 1970. In 2012, more than 300 million Frisbees were sold worldwide.

8 Post-it


The invention of the famous yellow Post-it was a stroke of luck. Researcher Dr. Spence Silver developed the special adhesive that sticks, but also releases easily. The aim of the research was, however, to create a very strong adhesive, and the invention was therefore not used. Art Fry, another employee at 3M, frustrated by the constant bookmarks that fell from his choir book. He had a 'eureka' moment and came up with the idea to use the Post-it.

6 Slinky


The Slinky, known in the Netherlands as "stair carpet", was invented in 1943 by naval engineer Richard James when he dropped a tension spring on the ground. The spring happily hopped up and down as James came up with the idea of ​​one of the most popular toys. The first 400 stair runners sold just before Christmas of 1945, and were sold out within no time. In 2012 there were more than 250 million Slinky’s sold.

5 Kellogg's Corn Flakes
