Walking Water – Mixing Primary Colours

Don’t you just love vibrant colours? We did this experiment to show how water can move and to learn about primary and secondary colours. It’s so simple and really fun to watch. All you need is 9 glass jars, some kitchen paper, water and food colouring.

Fill up six of your jars with water, put red food colouring in two, blue in two and yellow in two. Fold up 3 pieces of kitchen paper and follow the diagram below.

Water was absorbed by the kitchen paper and travelled into the empty jar. Here the two primary colours mixed making a secondary colour. We liked the green and orange but weren’t so impressed with the purple! Maybe our blue was too strong?!

From start to end this probably took a couple of hours. We were able to get on with other things and keep coming back to see what was happening. I think that M and Z will be asking to do this one again!

Have you done any experiments that your children ask to repeat? I’m always on the look out for engaging science.

Thanks for reading.

  1. We did this experiment once; though I only mixed up one jar of blue and one of yellow. My boys LOVED it. They also can not get enough of anything having to do with baking soda and vinegar. That fizzing action mesmerizes them every time.
