Erupting Sidewalk Chalk Paint

So this is a project we did this summer, but I’m thinking of doing it again this weekend. The weather is going to be beautiful this weekend, especially for November in Michigan! 

You will need some condiment bottles to do this project. I found ours for $0.89 at Walmart. The amount you needs depends on how many different colors you want to make. Also make sure you set one aside to hold just vinegar. The rest of the ingredients include water, corn starch, food coloring, and baking soda. 

As you can see we made four different colors. Mix equal parts corn starch, water, and baking soda. Once mixed add some drops of food coloring. We used about 20 drops. The more you use, the more vivid your color will be. Note: This is not something you can prepare ahead of time! If it sits to long the corn starch will harden. After you have finished mixing, pour them into the bottles. Fill one bottle with vinegar and set it aside. Head outside and let your little one squirt the paint on the driveway or patio.  

Babs loved making cool designs! When the paint ran out she was bummed. So I handed her the bottle of vinegar and showed her if she squirted it on her creations they would fizz and bubble up! She loved it!  When your ready to wash it off your driveway use the strongest setting in your hose sprayer. A simple rain won’t wash these creations away!

Materials Needed:

Condiment bottles

Food coloring-20 drops

Corn starch-2/3 cup

Water-2/3 cup

Baking soda-2/3 cup 

Vinegar- one bottle full 

Hope you enjoy!
