Homemade Sidewalk Paint {and a Surprise}


How to Make Homemade Sidewalk Paint — a Modern Mrs.
Remember earlier this summer when L and I sat down to create her Summer Bucket List? Well, we've been checking things off that list left and right lately, and I couldn't be happier! This past weekend J was able to knock four items off in one night by taking her out for a date, which included dinner at a local Chinese buffet restaurant, bowling, dessert at Rita's, and geocaching. Phew! No wonder he was asleep by the time I got home from my neighborhood baby shower. {If you want to see a Bucket List Progress Report, let me know!}

Anyway, one of the items on L's Bucket List was to make Sidewalk Paint, so here we are. This project is incredibly easy and inexpensive, and well-rounded as it doubles as a science and art project. L learned the reactive properties of mixing baking soda and vinegar, as well as basic color theory by mixing food coloring to create other colors. I will say this project is ingredient heavy, so it's a good thing the ingredients are so cheap, because you'll be needing more as soon as you're finished.

On with the fun!

For this project, you will need:

  • Plastic Squirt Bottles
  • Equal parts Corn Starch
  • Baking Soda
  • Water
  • and about 4-6 drops Food Coloring
DIY Sidewalk Paint Recipe — a Modern Mrs.
We used four drops of food coloring {eight when we had to mix colors, such as for the orange and purple}, which provided more of a pastel version of the colors. If you want richer/more vibrant colors, I would opt for six drops each, or to your liking.

We began with a funnel and these squirty condiment bottles we purchased from Walmart for $0.97 each. We added equal parts corn starch and baking soda, then our water, then our food coloring, and used a plastic knife to mix the ingredients before shaking. At first the consistency will be very thick, but after a moment it will thin out and become shakable. Once you've made your desired shades, head outside for some squirtable art fun!

Since food coloring comes in four primary colors {red, blue, green, and yellow}, we needed to mix colors to create the shades L wanted to use. This was where the basic color theory lesson comes into play. L had no idea prior to this that you could create the shades orange, green and purple by using other colors. She thought this was the coolest thing!

Considering we only filled our bottles halfway {because this project uses so much corn starch and baking soda}, the fun went by fast. However, the fun didn't stop there. We decided to really turn up the fun by filling up our fourth squirt bottle with white vinegar, and I told L to squirt her art. The result? A surprising artsy eruption!

Homemade Sidewalk Paint Eruption — a Modern Mrs.
Whoa! Now, I will tell you, you can make Homemade Sidewalk Paint without baking soda, but you won't be able to make it erupt like this. I thought it was a fun little bonus, and you can get a box of baking soda for $0.73 around here, so I figured why not. Besides, the look on L's face was priceless when she saw it foaming and fizzing. It's the little things...

And that's how we spent our afternoon. It hasn't rained yet, so our driveway is still very much decorated, and apparently quite the spectacle to neighborhood children. I'm anxious to see if any of them will give this a try.

What about you?

Will you be trying this with your kids? Will you go the science-y route by using baking soda, or will you stick to the non-eruptive version?
