Fizzing Sidewalk Paint

This Fizzing Sidewalk Paint is by far one of our kids’ most favorite play recipes.

Sidewalk chalk is fun, painting is fun, and making things fizz is also fun! Let’s do all three!

Fizzing Sidewalk Paint

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
  • Food coloring

Mix the dry ingredients and then add water, stirring until it’s 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!

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 activity?  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).
