7 WHICH BANDAGE STICKS ON THE LONGEST?

Problem

Which band-aid sticks the longest: Johnson & Johnson Tough Strips, CVS Health Plastic, or Assured Fabric?

Hypothesis

I think that Johnson Johnson is going to win between all three of them. The reason I think this is because it was expensive and one of the most common in the store.

Procedure

    1. Need to buy three or more different pairs of band-aids

    2. Turn on the faucet on medium water

    3. Put one of the band-aids on your knuckle

    4. At the same time put your hand under the water and start the timer flex as well

    5. Do the same thing for all three of the band-aids

Conclusion

After testing all of them, Johnson & Johnson proved to be the best sticking band-aid. In fact it stayed on 2 minutes, 3 seconds longer than the worst sticking band-aid. My hypothesis turned out to be correct. I learned that the Johnson & Johnson did the best and is probably one of the best band-aids out there.

WHICH BANDAGE STICKS ON THE LONGEST?

For my science fair project I tested which bandage, Johnson & Johnson Tough Strips, Assured fabric bandages, or CVS Health plastic bandage can withstand water the longest without peeling off? My hypothesis is that the Johnson & Johnson bandage will stay on the longest. The reason I think that is because it was the most expensive one. Also, it was the most common one at the store. If people use this bandage, then it means it works well and stays for a while. The reason I chose this topic was because it seemed a pretty interesting one to do. The other reason I did this was so I know which one stays on the longest for my benefit.

I started out my project by buying three different types of bandages. Then, I put one of each on my thumb knuckle, but not at the same time so they wouldn’t get stuck together. I stuck my hand under running warm water, started a timer, and moved my hand flexing my fingers. As I was flexing my hand, I counted how many times I flexed my hand before the bandage came loose. I repeated this process with the other two brands of bandages. I recorded the amount of time it took to loosen the band-aid and recorded the data. I then did another round of testing and then calculated the average of both testings for each bandage.

My average time flexing with the Johnson & Johnson band-aid was 245 times. As I was flexing I noticed that the band aid wasn't coming off so I stopped. The average time for the bandages to come off came to 3 minutes, 03 seconds. The average time flexing with the Fabric bandages was 45.5 times. The average time was 73 seconds. The Plastic bandage average flex time was 51.5 times and the average time was 81 seconds.

After testing all of them, Johnson & Johnson proved to be the best sticking band-aid. In fact it stayed on 2 minutes, 3 seconds longer than the worst sticking band-aid. My hypothesis turned out to be correct. I learned that the Johnson & Johnson did the best and is probably one of the best band-aids out there.
