Strength
Procedures :
Repeat the experiment number one but this time instead of cutting strips of paper towel lengthwise, cut them crosswise. The title of your results table will be:
Strength of paper towel strips cut crosswise
Compare your results in two tables.
You may repeat experiments number 1 and 2 for testing wet paper towels. In this case you will need to wet the paper just before pulling it with Newton spring scale.
In this experiment you test the absorption ability of paper towels.
Water absorption ability of different paper towels:
7.Subtract dry weight from wet weight for each brand and write the results in the last column of your table.
8.Use the water capacity column to determine which paper towel is a better absorber of water.
For our sample experiment we used the following material:
The data could be presented in written form or a bar graph would be an excellent visual method of displaying the final results. Each brand tested should have its own bar. The length of the bars would be proportional to the strength in Newtons of each strip.
All measurements should be recorded in the project book and may be presented in the final project report either as numerical data or shown as a bar graph. For each brand of detergent tested, the length of the bar should show the percentage of stain removed.
Using the trends in your experimental data and your experimental observations, try to answer your original questions. Is your hypothesis correct? Now is the time to pull together what happened, and assess the experiments you did.
What you have learned may allow you to answer other questions. Many questions are related. Several new questions may have occurred to you while doing experiments. You may now be able to understand or verify things that you discovered when gathering information for the project. Questions lead to more questions, which lead to additional hypothesis that need to be tested.
If you did not observe anything different than what happened with your control, the variable you changed may not affect the system you are investigating. If you did not observe a consistent, reproducible trend in your series of experimental runs there may be experimental errors affecting your results. The first thing to check is how you are making your measurements. Is the measurement method questionable or unreliable? Maybe you are reading a scale incorrectly, or maybe the measuring instrument is working erratically.
If you determine that experimental errors are influencing your results, carefully rethink the design of your experiments. Review each step of the procedure to find sources of potential errors. If possible, have a scientist review the procedure with you. Sometimes the designer of an experiment can miss the obvious.

If you want to know the strength of various brands of paper towels, you do not need a commercial to show you their take. Instead, do your own experiments at home and make your own educated decision. Purchase three to four different brands and then get home and start your various tests to find the strongest paper towel.
Tear off a sheet of each paper towel and be sure they are all whole pieces with no tears. Set out objects of varying weights, like an apple, a brick and a five-pound sack of sugar. Then, have one person hold the paper towel flat, in the air, with two hands on either side, while the other sets the object in the middle. Predetermine a length of time the object must stay on the paper towel before it counts as "strong enough to hold a..." Write down your observations for each brand, depending on how they preformed.
Take a new sheet of paper towel off each roll and soak them with water. Repeat the weight test with your objects to see if water makes any of them weaker or stronger. Write down your results for each. Then, while one person holds the paper towel flat in the air, place one of the objects in the center of the wet paper towel--the brick would work nicely--and see how long the paper towel can hold the weight. Before you start, make sure you have something--or someone--to catch the object when it finally falls through along with another person at the ready with a stop watch.
Grab another fresh sheet with no rips or tears from each brand of paper towel. Each sheet must be the same size to get an accurate result. This time, when one person holds the paper towel flat in the air, have another person use an eye dropper to drop water onto the middle of the paper towel. Place a bowl underneath the paper towel, because you will be counting the total number of drops each brand can hold before the water begins to drip into the bowl.

Science project, paper towel science project: capillarity.
Yikes! You’ve just spilled water all over the table! Never fear, there are paper towels nearby. As you clean up your mess you notice that water is spreading throughout the paper towel. What is going on here? The water is being absorbed, or soaked up, by the paper towel material through a process called capillary action. Capillary action, also known as capillarity , is the rising or absorption of liquids through small gaps and holes certain materials.
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). Water also likes to bind to certain other materials through a process called adhesion. In this paper towel science project, we will be testing which type of paper towel contains the highest rate of capillarity (or ability to absorb water into its many small spaces).
Which of your 5 paper towels demonstrates the highest level of absorption or capillary action?
What happened? Did you notice any major differences in terms of absorption levels? If you used a largely quilted, soft paper towel, you may have noticed that it absorbed more than others.
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. Ever notice how rough and flat the brown paper towels in your school restrooms are? They’re not very absorbent because they do not have the soft, puffy, quilted texture of other types of paper towels.
Paper towels are a great way to explore capillary action because they show the ways in which water and other liquids can move upwards through a material at different rates and quantities. Feel free to keep investigating! Have any celery in the refrigerator? Celery can also be a great example of capillary action. Mix water and food coloring in a cup. Submerge a freshly cut end of a stalk of celery and watch the color be pulled up through the stalk!

Problem- I am trying to figure out what paper towel is the strongest. I am tested this by getting wetting different brands of paper towel and placing as many pennies as I could on the paper towel before it ripped.
Hypothesis - In my project, I believe Bounty will be the strongest paper towel brand . I believe Bounty will win because I have used it a lot and I know it doesn’t tear easily. I also know that Bounty is good at absorbing an abundance of water.
1. Get a measuring bowl and put the same amount of water in it to wet the paper towel.
2. Place as many pennies on the wet paper towel until it starts tears
3. repeat 5 times for each different paper towel
4. When the paper towel rips count the pennies that were on the paper towel.
Conclusion- After experimenting the strongest paper towel was Bounty. The first time I experimented on bounty I got 230 pennies. The second time I experimented I got 215 pennies. The third time Bounty held 225 pennies.
Abstract- I am testing which paper towel brand is the best out of Bounty, Viva, Signature Home, and Sparkle. I believe Bounty will be the strongest because I have used it before and it didn’t rip or tear. I choose this topic because it’s important to have paper towels that don’t rip while you are cleaning the kitchen for just washing your hands.
While experimenting I first got a paper towel and soaked it in water. I used a measuring cup to make sure I have the same amount of water in each paper towel. Then, I placed as many pennies on the wet paper towel and lifted it when I added every time I added few more pennies. Once the paper towel ripped I counted how many pennies were on the paper towel when it broke.
For Bounty my average was 220 pennies. For Signature Home my average was 180 pennies. For Viva my average was 185 pennies. For Sparkle my average was 170 pennies. The average amount of pennies a paper towel can hold is about 200 pennies.
In the project I learned bounty is the best paper towel brand. My hypothesis was correct because I said bounty and it held the pennies and stayed strong the longest. I think my experiment was accurate because I didn’t use anything that could make something go wrong in my experiment. I think if I had something to hold up the paper towel while I was putting pennies down it would have made it a lot easier.
Graphs and data table:
This post is part of the DIY Summer Camp Activities series. Find more fun things for kids of all ages there .
I coach a homeschool Science Olympiad team and one of the events is Experimental Design. For the event, students use various provided materials to design and conduct an experiment on a specific topic.
For one of our practice sessions last year, I gave them different brands of paper towel and asked them to conduct an experiment on absorbency.
The result – for me – was that I changed my brand of paper towel!! Yes, the results were that dramatic.
So the DIY summer camp activity will not only be educational and fun for your children but should also be beneficial for you!
Here is a step by step walkthrough of the experiment. You can use more water and more paper towels if you are using a bigger glass. Just adapt to make it work with the equipment you are using.
Get your children to come up with a hypothesis as to what they expect to happen and why eg. We believe brand A will be the most absorbent, brand B then next absorbent and brand C the least absorbent because …..
1. Gather needed materials
2. Lay all paper towels on top of each other and use scissors to trim so they are all the same size (this way you’re testing how the absorbency of the towels differs and size isn’t a variable). You will need 3 pieces of each brand.
3. Take 1 paper towel from brand A and roll lengthwise so its diameter can fit in the graduated cylinder
4. Fill the graduated cylinder with lukewarm tap water to a volume of 30ml. (Note: we use metric measurements as that is standard in the scientific community).
5. Put a rolled paper towel in the cylinder so 3cm of the towel is submerged in the water
6. Hold the towel in water for 10 seconds, then lift it up out of the cylinder and allow to drip into the cylinder for 5 seconds. (The purpose for doing this was to make sure the test showed what the paper towels were absorbing AND keeping in. After all, you don’t want towels that drip out everything you’ve just cleaned up!)
7. Either dispose of paper towel in a waste bin OR place in pie pan and throw them all away at once when you finish
8. Record the volume of water remaining in the cylinder and subtract from the original 30ml to see how much water the towel absorbed
9. Repeat steps 3-8 two more times with the same brand of paper towel.
10. Now take the next brand of paper towel and do steps 3 – 9.
Record your data as you do the experiment. Once you are finished, calculate the average amount of water left for the 3 trials of each brand of paper towel.
Draw a bar graph of the average of the tests for each brand of paper towel. It will look something like this:
The independent variable in this experiment is the brand of paper towel i.e. it is the one the tester is changing. The independent variable is always on the X-axis.
The average amount of water (over the 3 trials) left in the cylinder is the dependent variable and the bar should be drawn to this height.
Now that you have the data, and the graph, students can reach a conclusion. They need to decide if their hypothesis was supported by the data or not (NOTE: scientists never say their hypothesis was ‘true’ or ‘false’ but only whether the result of their experiment supported the hypothesis or not)
Paper towel is made of plant fibers. Capillary action in the fibers draws the water into the paper towels. If you have a microscope, put a piece of paper towel under it for your children to look at. The fibers are made up of tiny linked sugar molecules called cellulose. Cellulose attracts water. If you look at paper towel under a microscope you will also see that there are spaces between the fibers – and those will hold water too.
To take this one step further, take a look at how much each roll of paper towel cost and try to calculate the cost of one “test strip” for each. Relate the cost to how absorbent the brand was and that should help you select what to buy in the future.
And your children can see a practical use for science!
Don’t forget to take a look at other DIY Summer Camp ideas to do with your children.

His little household experiment with a roll of paper towels reveals just how many spills one roll of Bounty paper towels can really absorb!
Rob is my hero.
I’ve been a fan of his website for a long time.
I like to help people find unique ways to do things that will save time & money — so I write about “outside the box” Household Tips and Life Hacks that most wouldn’t think of. I’m super-organized. And I LOVE to clean! I even enjoy doing laundry (but not ironing). I’m also a lifelong dog owner — so I often share my favorite tips for living with dogs inside your home (like smart home design choices and dog-friendly cleaning & decorating ideas). Career-wise, I’ve been sharing my best ideas with others by blogging full-time since 1998 (the same year that Google started… and before the days of Facebook and YouTube). Prior to that, I worked in Higher Ed over 10 years before switching gears to pursue activities that I’m truly passionate about instead. For example, I’ve worked at a vet, in a photo lab, and at a zoo — to name a few. I enjoy the outdoors via bicycle, motorcycle, Jeep, or RV. When I’m not cleaning, organizing, decorating, or fixing something… you’ll find me at the corner of Good News & Fun Times as publisher of The Fun Times Guide (32 fun & helpful websites). To date, I’ve personally written over 200 articles about cleaning, organization, DIY repairs, and household hacks on this site! A few have over 2M shares; many others have over 100K shares.

Place one paper towel over one pool of water. Wait ten seconds. Remove the paper towel, and record your findings of the paper towel absorbency in the notebook. Repeat steps 3 through 5 for each paper towel brand. Create a graph to illustrate the results of which paper towel absorbs the most water.
Method. Fill the beaker up with exactly 200 ml of water. Take a sheet of the first brand of towel. Fold and insert into the water. As you dip the towel into the water, start your stopwatch. After 20 seconds, remove the towel from the beaker and squeeze as much water as you can out of the towel in to the graduated cylinder using the funnel.
Have a couple of friends or family members hold each corner of the paper towel. The bowl catches any excess water and prevents a mess. Add five teaspoons of water to the paper towel, and then start placing coins on top of it, one at a time. Place all of the water in the center of the towel. Add quarters to the paper towel until it breaks.
Let's Roll! To start your rainbow science experiment, first line up your clear cups. In the first, third, fifth, and seventh cups, add water so they're a little more than half full. Prep your Bounty Paper Towels by folding each sheet in thirds lengthwise-you'll need six of these. Place to the side while we prep the colors.
This rainbow science experiment is as magic as the science behind it. The colored water travels up the paper towel by a process called capillary action. Capillary action is the ability of a liquid to flow upward, against gravity, in narrow spaces. This is the same thing that helps water climb from a plant's roots to the leaves in the tree tops.

In this experiment you test the absorption ability of paper towels. Procedures: Cut one sheet of each paper towel that you are testing and label them with a letter or a name that indicates each brand. Fold each sheet four times. That will make a small square that has 16 layers of paper towel.
Wet Strength. Take a new sheet of paper towel off each roll and soak them with water. Repeat the weight test with your objects to see if water makes any of them weaker or stronger. Write down your results for each. Then, while one person holds the paper towel flat in the air, place one of the objects in the center of the wet paper towel--the ...

Question Date: 2014-04-14. Answer 1: I did not know the answer to this question, but I was in the lab when I saw it and decided to do an experiment to find out. You could probably do a similar experiment at home. I used a simple paper towel that we have in the lab, not a brand name product. I weighed it - it weighed 2.2 gram.
The results of the experiment were that the Sparkle brand paper towels were the most absorbent. It absorbed on average, 50ml of water, when the Bounty brand paper towels absorbed only 44.75ml of water. Fundamental essentials best sponges we tested rated, so as: Bounty Select-A-Size 2-Ply. Brawny Pick-A-Size 2-Ply.
After conducting the experiment, our results show that the Bounty paper towel brand absorbed the most water (20 mL) out of all the five brands. The paper towel provided by the school absorbed the least amount of water (4 mL). The results from the experiment prove that my hypothesis was right, Bounty was the brand able to absorb the most water.

Fold the paper towel in half horizontally. 2. Cut off about 1/3 of the paper towel. Save the smaller section for later. 3. Draw the rainbow colors on one end of the paper towel in rectangular blocks. Make sure to go over the colors a few times with the markers so there is enough dye to travel up the paper towel. 4.
Varying amounts of water left after using each type of paper towel allowed for a comparative analysis of their absorbent capacities. Responding Variable: Type of Paper Towel: The specific variable responding to changes in the experiment was the type of paper towel being tested. This variable helped determine whether Bounty or the generic brand ...
