Recipe for making chalky paint for sensory play
- 1/4 cup cornflour (or corn starch)
- 2 tbsp water
- 2 drops of food colouring
What does it feel like?
Chalky paint that uses cornflour (cornstarch) makes the liquid thick when it experiences any friction. So if you were to run your finger through the liquid it would feel thick and hard to move, however, if you added your finger to the liquid slowly it would just feel like water.
This makes it a great science activity for children.
Possum wasn’t that excited about the idea of using her feel and so she chose to play with the chalky paint using her hands. Wonderful!
Important things to note
The chalky paint leaves behind markings like chalk once it has dried. From our experience, it was still slightly visible after about a week but I’m sure a pressure washer would remove any traces very quickly. I also recommend not using too much food colouring as it will stain hands if too much is used. 🙂
The few drops of food colouring that I did add to the recipe looked sensational as it was a great to see the colours as they swirled and combined together in certain areas.
