Experiment with Primary Colors

Materials Needed
  • Cup or jar
  • Cup of water
  • Drinking straw
  • Paper towels
  • Colored markers

There are three primary colors, red, blue and yellow. Did you know that all other colors are made by mixing different combinations of those three colors? In this experiment we will unmix some colors to take them apart.

  1. First you will need to cut some circles out the paper towels. Cut them larger than the opening of the cup or jar so that they will sit on top and cover the opening. Make one circle for each color of marker you will use.

  2. Next place a colored dot in the center of each circle. Touch the tip of the marker to the paper and hold it still for a moment to allow a little of the ink to soak into the paper. Be sure to choose several colors, not just red, blue and yellow. Purple, green, black, brown and orange are good choices.

  3. Set the first circle of paper towel onto the cup or jar with the colored dot in about the center of the opening.

  4. Dip the straw into the cup of water and put your finger over the straw opening to hold the water in the straw. Now place the straw over the ink dot and allow a few drops of water out, onto the ink dot.

What Happened?

The water mixed with the ink and caused it to separate into some of its original colors. These were the colors that were mixed together to get that color of ink in the marker.

The paper towel absorbed the different colors of ink at different speeds causing different inks to spread out farther than others.
