Have you ever tried to grow a rainbow?
This fun little experiment is super easy and can be done with items that most people would be able to find around the home.
All you need is:
- 2 Cups (Clear ones work best but any will do)
- A piece of paper towel
- Some coloured markers
Fold the piece of paper towel in thirds and colour the either end with a small block rainbow, like the picture below.
Fill your cups with water almost to the top. Take your paper towel and place each end in a cup.
Watch your rainbow grow!
