The purpose of my project is to find out which berry stains the most even after being washed by either Antibacterial Soap or Laundry Detergent. Also to find out how the chemical compositions of the four berries, (blueberries, blackberries, raspberries, and strawberries) affects the visibility of the stain on a cotton strip. I also learned that the flavonoid content in the berries plays a major role in the colour of the stain. My conclusion was that blackberries stain the most, I came up with this conclusion over a period of testing, and research.
