This is expected, as the tiny space between paper towel layers helps hold more water.
Paper is made of cellulose, which water molecules like to cling to. Paper towels are especially absorbent because their cellulose fibers have empty spaces—tiny air bubbles—between them.
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.
Cleanup Let your wet paper towels dry, then recycle them if possible.

In this experiment, we're going to be testing how much water paper towels can absorb.
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.
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.
