You can tell when the paper towel is maxed out because the water will pool on the table and no longer soak in. Repeat this process with the two other squares you cut from the same brand of paper towel.Then, average your number of drops for the three trials and record this number in your data table. If you're having trouble deciding what brands to test, try to think of things that set the brands apart.This is expected, as the tiny space between paper towel layers helps hold more water.

The water attaches to the cellulose and hangs out in the air space.

Thinner paper towels have less air space in between their cellulose molecules and thus hold less water.

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.

As you struggle and use half the roll of paper towels for one soda, you wonder if it would have been worth the money to get the more expensive brand. In this experiment, we're going to test the absorbency of different brands of paper towels. What evidence do you expect to see to prove your hypothesis? Start by cutting your paper towels into three inch square pieces. When it has completely soaked in, add another drop.

Before you start, think about what results you might get. Make sure you have three of each type, for a total of nine squares. Repeat this process until your paper towel can no longer hold anymore water.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.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?Magnifying your paper further will reveal that the fibers are made of long chains of linked sugar molecules, called cellulose.Water is attracted to cellulose and likes to be soaked up and stick to the cellulose in paper.These fibers are made of cellulose, long chains of sugar molecules linked together.Water sticks to cellulose through the process of cohesion, where water molecules adhere to other molecules.The next time you reach for the paper towels, remember to fold!You might feel good knowing you just saved an extra paper towel from being used.
