Science – Rainbow Colours!!

Science Rainbow Colours!!

We were way overdue for a fun experiment, so I broke out the materials for a paper towel experiment!

  • Water
  • Food colouring
  • Spoon to stir
  • Paper towels
  • Clear cups

This was so simple and worked like a charm! I put 5  plastic cups – filled with water, 2 empty.

  1. Add food colouring to each one and stir. We used yellow, green and blue.
  2. Roll a paper towel into a tight tube.
  3. Stick one end into one of the coloured waters, and the other end into the empty middle cup.
  4. Repeat for the other side, so that each cup has a paper towel that ends up in the middle cup, as seen above.
  5. Observe the water moving up the paper towel. Ours took a while to get down into the other cup (30 minutes).
