Kids Activities: Colour Changing Chalk

This colour changing chalk activity was fun and easy to make with ingredients that you probably have at home anyway.

    • Tomato Sauce Bottles/ Squirt Bottles
    • Maizena
    • Bicarbonate of Soda
    • Food Colouring
    • White Vinegar

Chalk Mix:
Fill bottles 2/3 with an equal mix of Maizena and Bicarbonate of Soda, add some food colouring to each bottle and then fill to the top with water. Use a butter knife to stir and then shake well.

Vinegar Mix:
Fill bottles with Vinegar and add some food colouring.

Give the bottles to the kids and watch them play. I took my daughter to visit the neighbours kids and their friends and they had a wonderful time.

The chalk mixture fixes and changes colours when the vinegar mixture is squirted on top of it and then makes chalk. It kept the kids busy for ages and they went through 10 bottles!

We are on a dirt road so the chalk mixed in with sand, I think doing it on a tarred road would be much more fun….
