1. Microwave Ovens
In 1945, Percy Spencer with the Raytheon Corporation as experimenting with a new vacuum tube called a magnetron when he noticed that the candy bar in his pocket began to melt. This intrigued Dc. Spencer to try another experiment with popcorns. Then he noticed that popcorns sputtered, careened and poped all over his lab. Spencer immediately saw the potential in this revolutionary process. In 1947, Raytheon built the first microwave oven, which was named the Radarange. It was weighed 750 pounds, 51/2 feet tall, and it cost about $5,000. However, when the Radarange first became available for home use in the early 1950s, its huge size that made it uneasy to carry around and expensive price made it unpopular with the market. Nevertheless a much more popular 100-volt, countertop version was introduced with a price of $495 in 1967. There are not much subsequent products that are based on Microwave Ovens.

2. Saccharin
Saccharin, the oldest artificial sweetener, was accidentally discovered in 1879 by researcher Constantine Fahlberg, who was working at Johns Hopkins University in the laboratory of professor Ira Remsen. Fahlberg was sitting in his lab, playing with new uses for coal tar, to no great success. He had spilled a chemical on his hands and he forgot to wash his hands before lunch, which caused the bread he ate to taste unusually sweet. In 1880, the two scientists jointly published the discovery. Then in 1884, Fahlberg got a patent and began mass-producing saccharin without Remsen. The use of saccharin became popular when sugar was rationed during World War I, and its popularity increased during the 1960s and 1970s because of the manufacture of Sweet'N Low and diet soft drinks, which can be seen as the subsequent innovations based on saccharin.

3. Slinky
In 1943, the sensitive springs were used to keep the fragile things steady on the boat. A naval engineer Richard James was trying to create a spring that would support and stabilize sensitive equipment on ships. He knocked one of the springs accidentally fell off a shelf and watch it continued moving. Then he got the idea for a toy. His wife came up with the name. 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 have been sold worldwide. Many toys today are using slinky as a part of their functions. Also slinky weights.
