We'll not only see which ones will be best to clean up spills, but also understand how they work through scientific properties of water.
Our goal is to answer the research question: ''Which brand of paper towels has the greatest absorbency? You've managed to spill cola all over your books and the floor while you were studying in the living room. You notice your family got the store brand instead of a brand name. Slowly apply one drop of water to the first brand of paper towels.
Taking an average of three trials will make your data more reliable. Do you want to see if the expensive brand is really worth it? What about if the paper towels are made from recycled materials?
To ensure you get accurate results, make sure you wait for the first drop of water to completely absorb before adding another.
Water molecules, which like to stay together, follow the one another as they are absorbed by the cellulose and fill the empty spaces.
Layering the paper towel creates more spaces for water to fill, which explains why your layered paper towel could hold more water and was more efficient at drying your hands.
Would the empty space between the sheets help to hold more water?
Materials Observations and results Did you measure a higher mass for the folded wet paper towel and did your hands feel drier when you used it?
Fiber types and construction patterns have also been demonstrated to have a large impact on absorbency in natural and synthetic textiles examined in a similar experiment (Beskisiz et al, 2009).
Both of these pieces of research suggest certain controls for the paper towel experiment described herein (Beuther et al, 2010; Bekisiz et al, 2009).
