We tend to hold inventors in high esteem, but often their discoveries were the result of an accident or twist of fate. This is true of many everyday items, including the following surprise inventions.
1. Play-Doh
One smell most people remember from childhood is the odor of Play-Doh, the brightly-colored, nontoxic modeling clay. Play-Doh was accidentally invented in 1955 by Joseph and Noah McVicker while trying to make a wallpaper cleaner. It was marketed a year later by toy manufacturer Rainbow Crafts. More than 700 million pounds of Play-Doh have sold since then, but the recipe remains a secret.
2. Fireworks
Fireworks originated in China some 2,000 years ago, and legend has it that they were accidentally invented by a cook who mixed together charcoal, sulfur, and saltpeter - ag by ironing together two pieces of waxed paper, thus keeping the chips fresh longer. Today, chips are packaged in plastic or foil bags or cardboard containers and come in a variety of flavors, including sour cream and onion, barbecue, and salt and vinegar.
4. Slinky
In 1943, naval engineer Richard James was trying to develop a spring that would support and stabilize sensitive equipment on ships. When one of the springs accidentally fell off a shelf, it continued moving, and James got the idea for a toy. His wife Betty came up with the name, and when the Slinky made its debut in late 1945, James sold 400 of the bouncy toys in 90 minutes. Today, more than 250 million Slinkys hav />A Post-it note is a small pie
