Autumn has arrived and the streets and parks are full of colorful leaves. Impress your company and, with the help of coffee filters and nail polish remover, learn what chromatography is and how it can help us see what pigments are contained in leaves. We believe you all know what photosynthesis is, but do you know why leaves change color in the fall? Bring in your leaf and check to see if the anthocyanin, carotene and xanthophyll have overpowered the chlorophyll. Compete with your friends to extract the pigments from your leaf the fastest. An exclusive gift: you can take home a filter paper on which you can see the separated pigments!
