Walking water

Firstly Ms Bracey was setting up a experiment for science last week.She put 7 cups into a line and filled up 1,3,5 and 7 with water and added food colouring the primary colours and Left 2,4 and 6 empty and than put in paper towel strips.The primary colours are red,yellow and blue and in Tongan kulakula mo engeenge .We worked in buddies and she gave us an observation sheet. Secondly we were asked to predict what will happen with the experiment.My prediction was the colors were going to mix and become secondary colors.My buddy had the same idea. Lastly, we waited for 3 days and our idea was right,so we were told to observe to write what we saw and we did.
