Paper Towel

Whether cleaning up messes or faces, you want a paper towel that is strong, absorbent, and soft to the touch. We tested absorption how much liquid each sheet absorbs and how quickly. We then measured the strength of each paper towel when wet, because no one wants a paper towel that crumbles under pressure. Paper towels are made up of ground-up plant material called cellulose, which can include wood, cotton, and other plants. The molecules of cellulose are actually sugar – but not like the sugar we eat – which attracts water molecules. Therefore, paper towels are great at picking up liquid spills. Fun fact: a paper towel's design is actually made of small crevices that help the paper towel have a better grip.
