Grow a rainbow

Here is a super simple experiment to do at home!  

You only need three things for this:

*A paper towel

*Felts

*Two bowls filled with water

Start by folding your paper towel piece into a rectangle.

Use felts to colour in both ends of the paper towel.

Place each end into the bowls of water and watch what happens!

Can you see what is happening? 

You made a rainbow!
