For my science fair project, I am going to test which paper towel brand is the best for absorbing whatever life calls for to be cleaned. I will be testing the brands Bounty, Scott, and Brawny. Paper towels seem simple, but there could be much behind how a paper towel cleans up life’s toughest messes. Paper towels are made up by cellulose fibers, which is also what makes up cotton, wood, and a lot of other plants. When the cellulose fibers are magnified and looked at, they are giant molecules that consist of many tiny molecules that are linked together. The key to absorption in a paper towel are the tiny molecules that combine together to make up cellulose. Cellulose fibers are sugar molecules. Think how easily sugar dissolves in water.

Quilting is part of what makes this possible. After the paper fibers mixed with resin are made into sheets, shapes are pressed into them that impart a quilted appearance. The quilted shapes form pockets of air that attract water and increase absorbency. There are two types of paper towels: folded and rolled. Folded paper towels come with a bifold or a multifold. People often pull multiple folded towels out of the dispenser, while a dispenser for rolled towels gives out one at a time. The process used to manufacture the towels also divides this paper product into different types. White paper towels are bleached using chemicals or a natural process depending on the brand. Paper towels with a light brown color are semibleached or unbleached. The last factor in paper towel absorbency is the number of plies, or stacks of paper. Kitchen paper towels also come in 1-ply and 2-ply, which means they are either 1 layer thick or 2 layers thick. As of absorbency, 2-ply kitchen paper towels are stronger and more absorbent than 1-ply kitchen towels because they have 2 layers of absorbent paper towel per sheet. But 1-ply towels can also do the
In this lab, three different brands of paper towel were tested to see which brand could absorb the most water. The brands that were tested were Bounty, Sparkle, and the Dutch Fork High School paper towels. To understand which paper towel would be the most absorbent one must know what makes paper towels absorbent in the first place. Studies show that, “Paper towels are made up of cellulose fibers, which also make up cotton, wood, and most other plants. These cellulose fibers are actually giant molecules that consist of many small molecules linked together. The small molecules that combine to make up cellulose are sugar molecules; that’s the key to the absorbency of paper towels.” (Brown, 2013). Other key factors that play into the absorbency
When you come to the paper towel aisle in the grocery store do you ever get frustrated and annoyed by all the brands to choose from? Every brand is telling you that they are the strongest and that their brand will absorb the fastest. Have you ever actually taken the time to figure out which brand is indomitable and absorbs the quickest? Well today I will fill you in on this mysterious secret and tell you not only which brand is not lying to you but also which brand you are getting your money’s worth and if paying that extra dollar is worth the name brand I think that the most expensive paper towel will be the strongest based on an ice cube suspended over a paper towel over a bowl held by a rubber band.
Bounty Paper Towels, known as the “The quicker picker upper” started in 1957 in Green Bay, Wisconsin. They are known as the quicker picker upper because they are so absorbent because of the pattern they have and also because they are 2-ply which makes them thicker and more absorbent. At the time, other brands were promoting how strong they were and how soft they were but did not really ever say much about how absorbent they were. After research they discovered that really all customers cared about was how much they absorbed, so that is what they started promoting. In 1965, they came out with a two-ply paper towel that was thicker and softer than any other paper towel on the market at that time. Bounty Paper Towels are made
Grandparents relate more closely to grandchildren than to their own children in many ways. Grandparents and their children can be stubborn and not want to deal with each other anymore because of problems from the past. After so long grandparents give up on their children and deal with them from a distance. Grandparents are more willing to relate to their grandchildren more than their children because it is another chance of getting to know their children through their grandchildren.
Three paper towels A, B, and C where tested on absorbency. This experiment was tested twice. Paper towel A was 26.5 by 28 centimeters. Paper towel B was 26.5 by 28 centimeters. Paper towel C was 15 by 28 centimeters. Scissors were obtained and each paper towel was cut to 13.5 by 15 centimeters. The weight of the three paper towels at this size was 0.9 grams dry for paper towel A, paper towel B weighed 0.8 grams dry, and paper towel C weighed 1.2 grams. Three beakers weighing 12.2 grams each were obtained. Each beaker was filled with 100ml of water with the outcome of them weighing 128.1 grams each. The weight of each paper towel dry was deducted from the weight of each paper towel. Paper towel A was left to soak for seven seconds.
Paper towels are made from softwood trees which contain long fibers. The tree goes thru several processes before it is actually turned into a paper towel. The paper towel is made from pulp in which the water is removed and the fibers then bond into sheets. Also, resin is added to the process to give the paper towel strength (Union). Several layers are then put together with adhesive and then formed into a paper towel (Choudhury). Some paper towels are embossed to form air pockets which help to absorb more liquid and help to add more strength (Union).
For example, a cotton bag from salt, would be washed, bleached, and cut into wash rags. The wash rags would eventually become one of the following; a dish cloth, a wash cloth, shoe-shining cloth, window-washing cloth, to scrub or wax floors, to make bandages, make kite tails, or to tie boxes and papers together. A lot of the time, a cloths would be used for all of those.

“First, the linen rags, were broken down into fibers. Second, the fibers were formed into a durable sheet of paper. The suspended fibers were created by pounding the rags in water. After the pounding, the fibers were then ground into pulp on stones and processed into a pasty liquid in a vat of water.The paper maker, then lowered a sheet of metal mesh into the slurry covering the mesh with the linen cellulose paste. The mold was lifted above the slurry as it was gently shaken, allowing the excess moisture to drain. The delicate, damp sheet was then carefully removed from the mold and placed between two pieces of felt on the flat table of a screw press. Then, the process was repeated and another wet sheet was added to the stack and topped by felt, and so on until a suitable stack of paper and felt separators was achieved. The stack was then squeezed with the press to purge as much water as possible from the sheets of paper. The sheets were then hung up to dry on a line
Paper towels were introduced for kitchen use in 1931 by the Scott Company and are one of the most versatile paper products. They are made from wood pulp which is then bleached to make them white. Resin is added to increase the paper's strength and the implicated water is then removed, allowing the fibers to bond and form paper sheets. Two layers are combined to create moisture-absorbing air pockets, and shapes are pressed into the paper to further improve absorbency.
The penny is the smallest coin in the United States monetary system based on both size and worth. It was made legal tender in 1864 and, in 1909 the image was changed to depict and honor President Abraham Lincoln. The penny has since outlived its usefulness and is now costing the treasury more than it is worth. Along with the rising cost of the penny, it also costs the world time, which is spent searching for pennies. The penny itself, cannot be used to buy goods alone. Since the imposition of the penny, the world has changed and the penny is now outdated and no longer useful.
In the following paragraphs I will be instructing you step by step on how to build your own PC (Personal Computer). It is recommended that you have general knowledge on computers. This means that you need to know what the different parts are and what they do.
To become a success in life, we all need to learn to become a good student in every aspect of life. Becoming a good student takes much work and self-discipline. There are many ways that a student can stand out from the rest of the class. These good students are distinguished by their attitude, intellectual skills, consciousness, and achievement.
The barracks are places great emphasis on cleanliness and well-being, both physically and leadership. In these places, even as much as a clean window is linked to physical cleanliness. More importantly, cleanliness is termed an indispensable fundamental of our role as a leader.
