Fizzing Sidewalk Paint
Sidewalk chalk is fun, painting is fun, making things fizz is also fun! Let’s do all three! This is a really simple recipe to create sidewalk chalk “paint” out of food coloring, baking soda and cornstarch. We have made the standard sidewalk chalk paint before, but this recipe is better – it fizzes when you spray it with vinegar.
To make your own fizzing sidewalk chalk you need:
A container of baking soda
1/2 cup of cornstarch
Warm (almost hot) Water
Mix the dry ingredients and then add water stirring until its not too thick. I think we used about a cup, but I am not sure. This paint dries very quickly – but washes off with ease!
We made two colors, my kids favorites: pink and green.
Here is the “before” it began fizzing. I love the brilliant colors.
Now for the fun! Spray the paint with a bottle of vinegar and watch the fizz appear.
To say this activity was a hit is an understatement. They are thrilled. We have leftovers! And clean up was a
bucketful breeze. Want to add more “learning to this activitiy? Talk about the reaction between acids and base chemicals. This is a fun way to incorporate chemistry into your preschoolers life (or just enjoy the fizz).
