Paper Towel Experiment

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

Paper towels are known for their absorbency. These towels are made of paper and are attended to be used once. Paper towels are used for cleaning and dry a variety of surfaces. During this lab, my group observed several brands of paper towels. Those brands included our school paper towels, Viva Vantage, Best Choice, and Bounty Basic. Our school paper towels were around 800 square feet long, had an average cost per roll of $5.25, and was single ply. This paper towel was brown in color, rough in texture, and dotted in pattern. Viva Vantage had 59 sheets per roll, had an average cost per roll of $2.09, and was single ply. The Viva Vantage was soft in texture, white in color, and had to apparent pattern. Best Choice had 111 sheets per roll, had

The Mythbusters observed the myth that driving whilst talking on the phone is as dangerous as driving drunk. They formed their hypothesis that driving on the phone is as dangerous as driving drunk. Then, they tested their hypothesis. They created an experiment that would have participants drive a car through a course three times. Each time a participant went through the course, they experience different conditions. The first time, both participants drove through the course normally. This served as the control group for the experiment. The second time, participants were asked questions over the phone while they completed the course, and, the third time, they were drunk when they drove through the course. Throughout the experiment, there were several independent variables in place to ensure that only one variable was being tested.

The concentrations and absorbances of the red and blue dyes were used to find the concentration of the purple dyes. From the graph of the blue dye, the linear equation for absorbance was y = mx + b. From that formula came the equation y = 7.915 x 104 (x) + 0.02489, where y represents absorbance, m is slope, x is concentration/molarity, and b is the constant/y-intercept. The same set up was performed for the red dye, but the equation produced was y = 1.045 x 104 (x) +.001298. The equations found when graphing absorbance vs. concentration were used to find the concentration of the purple dyes. The absorbance for purple dye 3 on the red wavelength of 470 nm equaled 0.149 and 0.818 for the blue wavelength of 635 nm. For purple dye 1

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.

Absorbency affects: skin comfort, static build-up, dimensional stability in water, stain removal, water repellency, and wrinkle recovery.

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 this experiment, the amounts of Red 40 and Blue 1 were quantified in six different Kool-Aid samples through the use of a spectrophotometer. This was completing by performing serial dilutions on both dyes, Red 40 and Blue 1, and then creating calibration curves for each of the six samples. The absorbance and maximum wavelength values were obtained from the spectrophotometer for each individual drink sample. Beer’s Law was used to discover the concentration of

When analyzing the IR spectrum of Ruthenium complex with DMSO, the prominent peak is presented at 1105.54 cm−1. This peak indicates that S=O bonded in DMSO. For DMSO, the frequency is around 1050 cm−1. From our spectra obtained for DMSO where the S=O peak is at 1017.65 cm−1. Since the bond appears at a higher frequency, this shows that the bond is strengthened by the reaction. This indicates that when the copper metal was combined with DMSO, it bonded with the Sulfur atom. Combining ruthenium with sulfur atom caused it to donate a pi electron as a back donation.

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

I've used several different laundry bags for washing over the years and have to say these Delicates Laundry Bags from Inside Smarts are by far my favorite!

The absorbance is measured using a Plate reader and a Standard curve is generated. Also, the different types of pipetting techniques are assessed in this Assay.

A bamboo towel is made of bamboo fibers. It is not chemically treated, and this means that it is free of any type of bacteria that can harm you. These products are highly recommended these days, when lots of things that surround us are full of chemicals that affect our health.
