Pen chromatography!

(All grade levels)

Create fun designs and watch the science happen right in front of your eyes!

It is quick, simple and fun!


  • Paper towel or coffee filter paper

  • Sharpies or Markers (black looks really cool!) (felt tip pens work great)

  • Water

  • A Glass


  1. Cut the filter paper or paper towels into thin 1 inch strips

  2. Draw a line about 1/2 inch with the marker above the bottom of the strip

  3. Carefully place the strip of paper into a cup slightly filled with water just so that the bottom of the strip touches the water

  4. Make sure to not place the whole strip in water

  5. Watch the colors separate and the magic happen!
