This week’s area of focus is SCIENCE, let’s discover how chromatography works.

You’ll need:

  • Two jars filled halfway with water
  • Washable markers
  • Paper towel/napkin
  • Scissors
  • Ruler


  1. Fold over a piece of paper towel (so you have 2 pieces on top of each other). Trim off 2-3 inches at the end.
  2. Colour two-inch rectangles of each colour on each end of the paper towel.
  3. Fill two glasses halfway with water and place them side by side.
  4. Place the paper towel in the cups, one in each and watch your rainbow grow!

This science experiment is a great example of chromatography. Chromatography can separate chemicals, the water lifts the washable marker dye with it up the paper towel.
