Which Paper Towels Has The Best Absorbency?
By James Gilmer
Project Design Plan
To determine which paper towel has the greatest absorbency. Paper towels were first introduced for the Scott Paper Company of Philadelphia to help prevent the spread of colds from cloth towels in bathrooms (Corkhill & Seder 2008). Paper towels are constructed of giant molecules consisting of smaller molecules of cellulose fibers (Brown 2013). The smaller molecules are made up of sugar molecules, which is the key to the absorption of paper towels.

Literature Review
There are multiple brands with each brand having different types of paper towels that vary in price that are sold in stores. Consumer Reports rated Bounty has the top paper towel for absorbency, …show more content…

The cylinder will be dried out after each turn
7. After 8 turns, drop the highest and lowest and divide by 6th to get the average

Tools and Technologies

Paper Towels
Water
Measuring Cup
Funnel
Graduated Cylinder
Stop Clock

Variables

Independent Variable = Different paper towel brands
Dependent Variable = Measurement of water in graduated cylinder
Controlled Variables = Amount of water; Time in water; Squeeze of paper towel

Threat reduction to internal validity

By using a purchased gallon of water ensures that the same water is used for each paper towel. By thoroughly drying the funnel and graduated cylinder each time helps ensure the exact measurement. Using the exact same squeezing technique helps ensure that one wasn’t squeezed harder than the other.

Hypothesis

The hypothesis of this experiment is that Bounty will be the most absorbent based on others reporting their own experiments of paper towels.
