FIZZINGSIDEWALK CHALK

WHAT YOU’LL NEED:• Cornstarch• Baking soda• Water• Food coloring• Squeeze bottles• White vinegar• Spray bottle• Measuring cups. 

HOW TO DO IT:1. Start by mixing up the base for the paint. Combine equal parts cornstarch, baking soda and water using a measuring cup. 2. Add this mixture to the squeeze bottle. Decide what color you want the paint to be and add a few drops of food coloring. Close the bottle and shake to combine. 3. Repeat this process until the bottles are filled. 4. Fill up a spray bottle with white vinegar. 5. Now you’re ready to go outside and start painting! Test an area of the sidewalk first to make sure the paint won’t stain – it should wash away with water. 6. Use the squeeze bottles to make some colorful creations on the sidewalk. Let these dry a bit and then spray with the vinegar and watch what happens! 7. Keep experimenting! See if you can get the paint to fizz more by changing the ratio of cornstarch, baking soda and water.
