Walking Water Rainbow!

We're going to walk through an experiment that is sure to amaze: the Walking Rainbow Experiment! Get ready to see water do some amazing tricks as it walks from one cup to another all on its own. It's like having your very own water acrobat!
Using a couple of household materials, we’ll get to witness a couple forces of nature in action. Are you ready to see water defy gravity?
The downloadable PDF worksheet for this experiment can be found here:

-Materials-
• 7 glasses or cups
• Water
• Food Colouring
• Paper Towel
-Procedure-
1. Line up the 7 glasses close to each other.
2. Fill the 1st, 3rd, 5th, and 7th glasses with water, right to the top.
3. Add 10 drops of red food colouring to the 1st and 7th glass.
4. Add 10 drops of yellow food colouring to the 3rd glass.
5. Add 10 drops of blue food colouring to the 5th glass.
6. Fold your half sheet of paper towel into a strip on one end. Fold it over 2 more times and tear that piece off. Repeat this until you have 6 total folded strips of paper towel.
7. Take your first strip of paper towel, put one end in the 1st glass and the other end in the 2nd empty glass. Repeat this, chaining all of the glasses together.
8. Observe as capillary action walks water from the full glasses into the empty glasses, bringing the colouring with it and blending them to make a rainbow!
