Which band-aid sticks the best?

Hypothesis: The waterproof band-aid will stick the best because it will block out the water and it will be very strong when it is stuck onto the skin.

Procedure:

Put different types of band-aids on different types of skin
Leave all band-aids on until they fall off
Record data
Repeat two times
When done, measure the time band-aid stayed on

Abstract-

Which type of band-aid sticks the best, waterproof band-aids, non-waterproof band-aids, or plastic band-aids. My hypothesis is that the waterproof band-aids will stick the best, because it would block out water. The reason why I did this experiment was because whenever I get a cut on my hand, I reach for a band-aid. As I do this, there are many different different types of brands to choose from. When I choose I can never get the right brand, and that is why I am doing my project. To save money.

The procedure for my experiment was to first to find different people with different skin types, then I put all three band-aids (plastic, waterproof, and non-waterproof band-aids) on my test subjects. After that, I left all the band-aids on the test subjects until the band-aids fall off, after this happens I record what band-aid falls off and when they fall off. As soon as I complete the first test, I repeat the test two more times.

I tested different band-aids on different skin types, and the result is that my hypothesis was partially correct because, on the soft and bumpy skin, waterproof band-aids were in second place for stickiest band-aid. To prove this, the average time the band-aids were on the bumpy and smooth skin was one day for waterproof and non-waterproof band-aids, and two days or the plastic band-aid. On the soft and bumpy skin, the waterproof band-aid stayed for two days, the non-waterproof stayed on for six days, and the plastic stayed on for one day. In conclusion, the best band-aid was the plastic band-aid on the bumpy and smooth skin and the non-waterproof band-aid was the stickiest band-aid on the soft and bumpy skin.
