Who Invented Plastic Wrap?...

Plastic wrap is such a common and ordinary thing you can find in every house every day. If you have food left over after a meal it is sometimes quite common to put them in a plate and cover them with this film. The idea is to cover and seal off any food you want to put inside containers in order to keep them fresh. Its invention is credited to Ralph Wiley from Dow Chemical. You will usually get plastic wrap in rolls contained in boxes. Each box usually comes with a cutting edge to make cutting the plastic film a lot easier. Every plastic film sticks to containers like an adhesive sealing food tight. It takes on different names depending on the location. In the United Kingdom, it’s called a cling-film. Some people in the United States call it cling wrap while it is called glad wrap. Invention of the Plastic Wrap The very first sheet of plastic ever used for wrapping anything was called cellophane. It was invented by Jacques Brandenberger, a Swiss chemist, in 1911. It was used as packaging and was quite favored due to the fact that it was transparent. However, it was never used to wrap or seal food. Needless to say, that isn’t the same as the plastic wrap that we use nowadays. The plastic wrap that we are familiar with is used primarily to wrap or cover food. Saran is the very first sheet of plastic to be used to wrap food. Saran or Saran Wrap is a trade name of Dow Chemical. This actually refers to various polymers and monomers that has properties that act like a barrier. Compared to other plastics, this plastic wrap is able to contain aroma...
Who Invented the Skyscraper?

Who Invented the Skyscraper?...

Defined as a super tall building that is continuously habitable, a skyscraper is a fascinating invention. The Empire State Building in New York City, the Willis Tower in Chicago and the Taipei 101 in Taiwan are just some of the most impressive skyscrapers ever created. Today, these buildings serve as practical solutions to the increasing scarcity of land worldwide. Aside from these things, it is also good to know the history of these tall buildings including who invented the skyscraper. The Invention of the Skyscraper Who invented the skyscraper? After he created the first ever load-bearing structural frame for the Home Insurance Building within the City of Chicago in Illinois in 1885, it is but right to credit architect William Le Baron Jenney as the Father of American skyscrapers. The ten-storey building was the very first skyscraper in the world. In 1891, American architects Louis Sullivan and Dankmar Adler designed the Wainwright Building in Saint Louis, Missouri. It was also a ten-storey building. However, many people considered it the first true skyscraper rather than the Home Insurance Building because it was constructed with steel frames. Furthermore, it featured vertical bands, which helped emphasized the building’s height even more. Additional Facts and Other Interesting Information After the early skyscrapers were created, fire restrictions and height limits were introduced. In 1895, the American Surety Building was completed in New York. It was the tallest building during that time. In 1930, the Chrysler Building was completed in New York City. In 1931, the Empire State Building, which was comprised of 102 floors, was completed. In 1932, the Boerentoren was constructed in Antwerp, Belgium. It was made up of 26 floors. In 1940, the Torre Piacentini was completed with 31 floors within the...
Who Invented the Outhouse?

Who Invented the Outhouse?...

Bowel movement being a basic universal need, it’s easy to imagine how the man who invented the outhouse came up with the idea. But who was the first latrine maker? Prehistoric Times Defecation in ancient times is thought to have been done indiscriminately. Prehistoric men released human waste anywhere in the forest. But soon, as the idea of privacy was beginning to take shape in their minds, they began to do it in isolation in caves. This was the crudest form of an outhouse by the first latrine maker or makers. Some studies estimate this to have happened about the same time when man learned to dress up. But the problem of available space in the latrine caves soon started troubling them. Thus, probably for convenience sake, they started digging holes for the purpose and partly refilling it with earth to make it reusable by others. Then, as refilling reached the level of the ground, they dug another site. As they advanced in living standards, people started living in constructed shelters of wood and thick canvas, and much later, wood and stone. The idea of communities also began to propagate. About that time, caves were too isolated and dangerous to continue serving the defecation needs of the people. The person or persons who invented the outhouse came up with the idea at this time. It Really Started in China The earliest record of a water closet system was in China. A stone toilet bowl with a water system was found to have been used in 206 B.C. Thus, the first latrine maker and the person who invented the outhouse could well have been a Chinese who lived around this time. Outhouses in Europe Some experts estimate that the first...

Who Invented Chalk?

Who Invented Chalk?

Your first encounter with chalk might have been in the classroom where you often see your teachers use them to write on a chalkboard. The most familiar form of chalk a lot of people have come familiar with is made of slender sticks around a quarter of an inch thick and about three inches long. You might even have come to wonder who invented chalk. Who Invented Chalk It might come as a disappointment to find out that no one can tell who invented chalk. Chalk is readily found in nature and has been used as a tool for drawing and writing for quite a long time. Drawings that date even to the prehistoric times have been discovered by archaeologists. The earliest chalk writings/drawings have been found in caves. As time went by artists from various countries used chalk to make drawings and sketches. Their work was protected using shellac or any comparable substance. For the convenience of these artists, a major innovation was introduced – chalks shaped into sticks. Even though chalk artists can’t be credited as the ones who invented chalk, their need introduced an innovation that would last for centuries. Making Chalk In the same way we don’t know who invented chalk, we also don’t know who invented the method to make chalk into sticks. What we know is that the method starts by grinding natural chalk into a very fine powdery form. Water is then added along with clay and various color pigments depending on what color of chalk you want to make. The clay actually acts as a binder of some sort. The mixture will initially look something like putty that would be rolled and shaped into cylinders and then would be left to...
Who Invented the Smoke Detector?

Who Invented the Smoke Detector?...

The history of smoke detectors started with American inventor Francis Robbins Upton. He created the first fire alarm in 1890. The patent no. was 436,961. He was a colleague of Thomas Edison but there’s evidence Edison worked on the device. Other Smoke Detectors Upton’s invention was very basic and other models would appear. The next one appeared by accident. In 1930. Swiss physicist Walter Jaeger was trying to make a sensor for poisonous gas. He was hoping that the gas would go in the sensor and ionize air. But the gas didn’t alter any currents. Jaeger lit a cigarette and saw the meter current go down. Jaeger’s discovery that smoke would affect the sensors changed the history of smoke detectors and how they were made. The Emergence of Home Smoke Detectors But these devices hardly made an impact. Electronic equipment made manufacturing very expensive. It wasn’t until the mid 1960s that affordable smoke alarms could be made. The few smoke detectors that were available were so expensive only large companies bothered to install them. The first home detectors were made by  Duane Pearsall in 1965. Their model made use of batteries. The design made it easy for homeowners to replace them. In 1975 Peterson and Pearsall began manufacturing smoke detectors. Their company Statitrol Corp was the first in the history of smoke detectors to sell the products. These models were comprised of metal and resistant to fire. The battery was made by Gates Energy. It didn’t take long before the rechargeable batteries were replaced by double A batteries. The devices proved very successful. By 1977, the company was shipping 500 units daily. In 1980, Statitrol sold its invention rights to Emerson Electrics. Sears would end up selling the product....
