Primary Colours Squishy Bag Experiment

Mixing Primary colours squishy bag experiment - follow on activity from the book Little Yellow and Little Blue

Primary Colours Squishy Bag Experiment is a wonderful sensory experience for children to see how colours mix and form other colours. Children use their hands to blends and squish the different coloured paints together for form new colours.

The three primary colours, red, blue and yellow are the minimum number of colours that can be mixed to make the greatest number of other colours or secondary colours.

Primary Colours Squishy Bag Experiment is a fabulous follow on from the stories Little Blue and Little Yellow by Leo Lionni and Red, Blue, Yellow Shoe by Tana Hoban

What you will need?

Mixing primary colours in a squishy bag experiment

You will need a large tray (or flat surface), red, blue and red paint, clear plastic zip lock lunch bags and sticky tape.

The sticky tape is used to seal and strengthen the openings of the zip lock bag and to also tape the bags onto a flat surface.

Mixing Primary Colours Squishy Bag Experiment

Some Ideas:

  • Place the two coloured paints for each zip lock bag in the corners opposite each other. One bag with blue and yellow, second bag with red and blue and the third bag with red and yellow.
  • Use sticky tape to seal and strengthen the squishy bags. If you are concerned the bag may break, you can double bag it for extra strength. I find that by fastening the squishy bags flat on a surface with sticky tape also assists in avoiding the bag breaking.
  • Read the stories Little Blue and Little Yellow or Red, Blue, Yellow Shoe and talk about the colours and what it happening in the stories.
  • Gently press and push the paints to the centre of the bag to blend. Using your fingers gently rub the paint to mix and blend.
  • Watch as the colours blend together. Make predictions and talk about what is happening throughout the process. Use descriptive language.
  • Label and name each colour throughout and talk about the new colours that they see.
  • Ask questions, such as, which two colours made green? Name other objects that are green? Can you go and find me something that is green? What do you see? What does the squishy bag feel like?

  1. I do this with my 2yo, but when he’s done, I peel the bag open and press it to a canvas. It makes spectacular paintings.
