Separate Colors with Water

Science of Art: Separating Colors

Materials:

paper towels, scissors, colored markers, water, jar

Procedure:

  1. With a pair of compasses draw some circles onto paper towels(or you can use a round cookie cutter). Cut them out with scissors.
  2. Using markers of different colors (black, purple, green, brown and orange are good colors to use) to draw a dot (about the size of a dime) of color in the middle of each circle.
  3. Place each circle of paper towel over the top of a clean dry jar.
  4. Add drops of water to the dot of color, use an eye dropper or a straw.
  5. Allow the color to spread and dry.

Result:

Rings of different colors will appear.

Explanation:

You will see that as the water spreads the colors will travel at different speeds and you will see that each color will create a ring. In printing and painting there are three primary colors – red, blue, and yellow. The enormous variety of colored dyes, paints, and inks are made by mixing different amounts of two or more of the primary colors.
