If you look carefully at color images inside of books with a magnifying glass or a microscope, you’ll find there are only four colors that make up all the different colors you see. We’re going to learn how to separate the color that makes up different color markers, which work the same was as the colored printed images in books.

Materials:


  • markers
  • blotting paper, paper towel, or coffee filters
  • water bottle
  • scissors


The different chemicals in the ink travel at different speeds along the surface of the paper when mixed with water. This is used to separate substances into its components.

  1. There are several listed above the ninhydrin that will work, but a couple of them require supervision of someone who really knows and understands how to work with chemicals. Stick to the first couple and you should be fine! Look at the text right above where it says experiment 3 on the Fingerprinting experiment.
