Originally published in Early spring, 2011, this is by far one of our kids most favorite play recipes.
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.
If you like this kids activity, we bet you’ll like the other 100 activities and recipes found in our book – a real, in-paper book!!! 101 Kids activities, available on both Barnes and Noble and Amazon <— “It’s pinterest for my kids, they browsed and planned for hours” (that was a recent review we got, made our day).
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 three colors, my kids favorites: pink, yellow and blue.
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 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).
If you make fizzing sidewalk paint, tell me about it!
