Which Towel is The Quicker-Picker Upper!
To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion that the Bounty Cooking paper towel is the Quicker-Picker-Upper as it absorbed about 21.8mL of the water in 20 seconds as oppose to Marcal (19.2mL) Stop & Shop (13.8mL) and the generic school brand (1.8mL). Juice or water spills seem to be the most common accidents, and the quickest way to clean them up is by using paper towels. Because they are made from trees, paper towels consist of giant cellulose molecules which are highly hydrophilic (have an affinity for water) because of the hydrogen and oxygen atoms located on their outer edges. Much like the trees use properties of water for capillary action which moves water up from the roots to the leaves, the paper towels also use water’s cohesive(attraction of a water molecule to another water molecule) and adhesive(attraction of a water molecule to another hydrophilic molecule) behaviors to soak up water. The water bonds with the cellulose because of adhesive behavior and therefore soaks the towel. Although paper towels work in similar ways, the absorbance rate varies between different brands. A lot of different towel brands such as Bounty , Marcal, and even generic brands and Stop & Shop paper towels claim to be the best at cleaning up spills, but which one of them is the Quicker-Picker-Upper? This experiment was designed to determine which brand of towel is best used for cleaning spills by measuring the towel’s absorbance rate. Hypothesis: If Bounty Cooking paper towel is used, it will absorb the...
