Every day, a technology and scientific breakthrough appear to solve problems and meet human needs. Scientists also spent a long time in the laboratory to perfect their findings.
However, certainly the research carried out does not always always succeed. Many things turned out to be unsuccessful and failed miserably. But there are also those who are unsuccessful but actually get unexpected new technology. Finally, this failure results in use value.
The following is a useful line of research errors and finally still used. Many of these inventions are household appliances. Launch Listverse, following the review.
1. Teflon
Teflon cookware is certainly one of the technological inventions that is very useful in the cooking world. Without a sticky pan, the food will be sticky when cooked and difficult to serve or wash.
Teflon itself, or the scientific name is PTFE or polytetrafluoroethylene in the scientific world, actually discovered accidentally when scientists from DuPont, Roy Plunkett, were developing a new CFC cooler.
When he opened the gas cylinder for experiments, he found a reaction between polytetrafluoroethylene and iron shell from the tube. The result is a wax that looks useless. Finally in 1954, there was the idea of coating cookware with this substance but which had been developed, to prevent the food from sticking to the pan.
Finally, until now, almost all modern cooking utensils are coated with various kinds of Teflon with various types.
2. Window Film
Glass has been in human life for a long time. Ancient humans used it in fancy building windows, so high art, jewelry, and so on. The main problem with glass in ancient times was that it was easy to break and the fragments were sharp and dangerous.
Today's glass that we find in cars is like window film and safe glass, the fragments will not be dangerous. Even so, the discovery of this thing is something coincidental.
French chemist named Edouard Benedictus accidentally dropped a beaker. The glass does not really break because the glass contains cellulose nitrate which leaves the film layer in the glass.
Finally this plastic-coated glass was further developed, but was initially used for tear gas helmets for World War I. But eventually these various types of glass were developed and became increasingly common in everyday items.
3. Microwave
Microwave is one of the most useful gadgets in the kitchen. But like the theme of this article, the discovery of this tool is not intentional.
Starting from Percy Spencer, a radar engineer, who was conducting experiments on magnetrons. Magnetron is a vacuum tube that was first discovered in 1945.
In this experiment, he accidentally melted the chocolate in his pocket. To further analyze, he brought dry corn and finally turned into pop corn. He accidentally found a new way of cooking.
Finally in the 1960s, Microwave went on sale in the market. After years of trial and error making this microwave with difficulty. Starting in size that is too large, until the heating process is quite long.
4. Plastic
At present, it is very difficult to find plastic. Within a meter of our current location, there must be something made of plastic. Even our sea is now filled with garbage dominated by plastic waste. At present, the use of this one ingredient is being minimized.
Plastics themselves were originally developed precisely to protect wildlife. When humans used to hunt for elephant ivory, turtle skin, horns, and many other animals, plastic was created to replace that.
This also appeared accidentally, because initially in 1869, a scientist named John Hyatt was assigned to find a replacement for billiard balls from elephant ivory. The substance was not found, instead he found a substance with a combination of cellulose, which is as well as cotton, which is combined with camphor. As a result, a substance is flexible, strong, and can be printed.
This discovery was increasingly developed so that synthetic plastic was found, which really cannot melt. Finally this component is used in everything that we use now.
5. Stainless Steel (Stainless Steel)
Stainless steel is one of the most revolutionary inventions, and is widely applied in items around us. Stainless Steel itself was found from accidental development of iron and steel.
Initially, a mixture of steel was developed but not rust. After that, when iron for the gun barrel was developed, a metallurgist named Harry Brearley experimented to add chromium to molten metal. The rifle barrel remains rusty, but instead the metal that it removes does not rust.
Finally, this waste metal is marketed as a silver substitute dinnerware.
The next development was developed and finally stainless steel was increasingly unable to rust. Finally this type of iron is used in vehicles such as trains and airplanes. You will also always see this type of iron in the kitchen or building location.
6. Bubble Wrap
We might know bubble wrap as a letus toy to get rid of boredom. But the original function of this is to protect our goods from shocks and reduce their impact when they fall. However, far from its original function, bubble wrap initially functioned as a textured wallpaper.
Two scientists named Alfred Fielding and Marc Chavennes heated two sheets of bathroom curtains through a heater, making it a piece of plastic with bubbles in the center. They intend to make it a wall decoration but not really good.
Then a little scientific idea emerged to make it greenhouse insulation. But after the experiment, finally this idea also failed.
Finally, after the plastic was useless, IBM used the plastic to protect its computer components when transported. Finally, bubble wrap is used to wrap electronics and glassware which are packaged to date.
7. Safety pins
Safety pins may be one item that is small in shape but of great use. Of course, his discovery happened accidentally.
Some ordinary mechanic named Walter Hunt fiddles with a piece of wire, so that when in a certain position he manages to make it a pin. Aware of its usefulness not in terms of mechanics but for trivial matters, it perfects it.
He added a kind of twist that made it look like a spring, sharpening the end of the wire to become like a needle, then making a safety while closing the end of the tip.
Hunt finally succeeded in patenting this pin discovery. He also succeeded in developing a pointed needle sewing machine, but his invention was copied by someone else and patented. He himself was in debt and sold his security patents.
