Which paper towel is strongest science fair project?

The Bounty paper towel was the strongest. Zoë Miller After being soaked, the Bounty towel held an impressive 43 ounces or 2.69 pounds.

Which paper towel absorbs the most liquid?

In our absorbency tests, Viva proved to be #1. These cloth-like paper towels were able to absorb the most liquid out of every brand tested, while also picking up spills quickly. Viva paper towels were also the softest paper towels, according to our consumer testers.

What makes a paper towel strong?

Paper towels are made from the same types of plant fibers that other types of paper are made from. The difference between paper towels and other types of paper comes when the paper fibers are mixed with a special type of resin to make them strong when they are wet.

Why do paper towels absorb water?

Paper is made of cellulose, which water molecules like to cling to. As a result, paper readily absorbs water. Paper towels are especially absorbent because their cellulose fibers have empty spaces—tiny air bubbles—between them.

Which paper towel is the best hypothesis?

Three different brands of paper towels were tested. These included Bounty, Viva, and Sparkle brand paper towels. It was hypothesized that Viva paper towels would be the most absorbent.

Why does water flow upward in paper towel?

Capillary action is all around us every day If you dip a paper towel in water, you will see it “magically” climb up the towel, appearing to ignore gravity. You are seeing capillary action in action, and “climbing up” is about right – the water molecules climb up the towel and drag other water molecules along.

Why do thicker paper towels absorb more water?

If a towel is thicker, it has more fibers to absorb water with! The fibers in tissues and paper towels are made of cellulose molecules—big molecules that consist of lots of tiny sugar molecules chained together.

How much water can paper towels absorb?

Then the water was squeezed into a measuring cup. The amount absorbed was recorded onto a chart. Each paper towel was tested three times. The results showed that Bounty absorbed an average of 16 mL of water, Viva absorbed an average of 15 mL of water, and Sparkle absorbed and average of 14 mL of water.

Which property is demonstrated when paper towels absorb a water spill?

Paper towels are permeable and porous, meaning that they contain small spaces that both liquid and air may pass through. Liquid is able to rise through a property of water called cohesion—that is, water molecules like to stay close to one another (which also helps to explain surface tension).

Which type of paper towel did the water rise higher on?

Water wants to be wherever it can be held and kept together through cohesion and adhesion. In this case, the puffier, softer paper towels were able to hold more water because their capillarity was greater. This is due to their larger holes and pockets, which can hold more water than standard paper towels.
