Water VS Johnson's Baby Oil

Purpose:
We will be trying to figure out which liquid can the diaper absorbers the most in two and a half minutes. We will be using size 3 pampers diaper as a control group, and Johnson's Baby Oil and water for independent variable. We choose Johnson's baby oil as an independent variable because the thickness of the Johnson's baby oil is close to the thickness of runny poop, also we choose water because it is close to urine that babies produce.
We will pour the 100-700ml of Johnson's baby oil and water onto the diaper one at a time. After each test we will wait for two and half minutes ( every after 100MLs add another minute) and then test it with a dry paper towel. Each time we do the same experiment we will be pouring both of the liquids in the same diaper but at different times. In the end we will find the results of the comparison by the seeing which liquid could absorbers the most in two and half minutes or higher. Also we will find the results by seeing how much liquid can the diaper hold. This experiment will help parents know how long does it take to let pampers diapers to absorb and how much weigh can the diaper pick up. That’s very important to parents because if a diaper doesn’t absorb fast enough then the babies will tend to get rashes. Also it’s very important to parents to know the right time to change the diaper and seeing how much a diaper could hold is the answer.
Hypothesis:
If you pour Johnson's baby oil onto the diaper than the diaper will hold more liquid than usual because Johnson's baby oil is more thicker and weighs more than normal water.
Variables:
Independent: Type of liquid.
Dependent: Amount of water and Johnson's baby oil.
Constant: Pampers size 3, same way of pouring, same way of towel check, and the same time.
Materials:
1. Two size 3 pampers diapers
2. Dry paper towel
3. One 100ml graduated cylinder
4. Water
5. Johnson's baby oil
6. Stopwatch
Procedure:
1. Open the diaper on the table.
2. Fill the 100ml graduated cylinder with water or Johnson's baby oil depends what liquid your using first.
3. Pour 100-700ml of water or Johnson's baby oil evenly over the diaper.
4. Start the stopwatch and wait for two and half minutes.
5. Sway the diaper around (move it nice and slowly)
6. When two and half minutes are up, take the dry paper towel and slightly rub it over the diaper.
7. If dry, repeat the experiment. . Try Experiment with a different amount of liquid or different liquid, each time you increase 100 ML of liquid, add another minute with it.
8. If the paper towel is wet, don’t continue the experiment.

Evaluation
My hypothesis was somewhat correct, although Johnson’s baby oil weighs more than normal water; when I poured it onto the diaper it stayed dry. Pampers is great for keeping babies feeling dry, and it dries quickly. The diaper took a little bit more time to absorb the Johnson's baby oil than water, which is what happens in reality because runny poop takes a little bit more time than urine to absorb. In total Pampers diapers could hold 300MLs of urine and under 300MLs of runny poop. The thing that we did wrong was that every time we did our experiment we added another minute, which makes it not a constant variable. The thing that we could improve on is being more punctual on time; we were off by few seconds for some of the trials. If I had anything that I could change on the experiment, that would be the time. We should have had a longer time to let the diaper absorb. All our trials returned to give us a positive result expect the 300Ml Johnson’s baby oil. When we poured 300Mls of Johnson’s baby oil onto the diaper, the cotton of the diaper didn’t let the baby oil break on. At that part our experiment went kind of unsuccessful. This states the fact that Pampers size 3 diapers can hold up to 400MLs of runny poop and it could hold more than 500MLs for urine. 
Analysis
The two graphs above explain that Pampers size 3 diapers could pick up around 1000Mls in total using the Johnson's Baby oil as runny poop and water as urine, which is quite a lot. After the 400MLS of Johnson's Baby Oil the cotton of the diaper didn’t let the oil break through. This in reality explains that you need to change the baby’s diaper.
In the end of the experiment I opened the diaper from the inside and I found something that looks like crystals and scientifically those crystals are called polymer. The Pampers diaper is composed of an inner layer of polyester that allows liquids to pass through to the layer of absorbent material, and the outer waterproof plastic of polyethylene. Pampers diapers have a special, extra-wide Ultra Absorb layer. This layer contains a gelling material called a super absorber, which is capable of absorbing 30 times their weight, to help lock moisture away from baby’s skin. Liquid passes through the 3 layers of absorbent material and is locked away in the super absorbent core, keeping wetness far away from the baby's skin, helping them stay comfortable and rash free. The inner lining that touches the baby's skin is usually made of polypropylene. Both materials are considered completely safe for babies’ skin. Pampers improve the inner lining with aloe and vitamin E, skin-friendly compounds that are often found in diaper rash creams. So basically, Diapers are usually made of plastic, paper and a crystal called sodium polyacrylate. When this sodium polyacrylate is exposed to water it turns into a gel that can absorb a tremendous amount of water.
