Inspired by a post at Infarrantly Creative, I decided to take our weekly play group to the next level with some sidewalk chalk spray.
First, add 1/2 cup cornstarch to a small container, preferably one with a spout. I used a simple pyrex measuring cup.
Next, add one cup hot water.
Then add one teaspoon tempura paint.
Last, add a small squirt of dishwashing detergent and mix well. Pour in your squirt bottles and your good to go!
As you can see, the spray was a huge hit at the play group. The bottles were pretty much empty when it was all over and my driveway looked like a Jackson Pollock painting!
