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.

fizzing sidewalk paint - this is chalk-lile paint that when you spray it with vinegar bubbles.

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 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. fizzing paint after the fizz

Now for the fun!  Spray the paint with a bottle of vinegar and watch the fizz appear. fizzing paint spray fizzing paint fizzing

To say this activity was a hit is an understatement.  They are thrilled.  We have leftovers!  fizzing sidewalk paint .

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).


If you make fizzing sidewalk paint, tell me about it!
