Here we are again with another fun idea I got from Pinterest! We are working on our Summer Bucket List 2012 and when I saw this idea to "Make your Own Sidewalk Paint" it looked easy enough (and fun) so I added it to our list!
All you need is cornstarch, water and food coloring. I couldn't find the liquid food coloring - what the heck? - so I found gel food coloring in squeezable tubes in the baking isle at the store. Do they even make liquid any more? I was kinda bummed but the gels worked fine. I almost busted out my nice gels that I use with cakes ;-) just to make even more variety of colors. But those are too expensive to waste.
The recipe I originally found says to use 2 tbsp cornstarch with 2 - 4 tbsp water. I tried the 1:1 ratio and the 1:2 ratio and found that the 1:1 was too think to spread onto our concrete. It wouldn't spread off the paint brush at all and just clumped and dried at the end of the bristles. The interesting thing that I found is that the 1:2 ratio was like the Crayola Color Wonder paints. It was a delayed reaction once the paint was on the concrete it took a few moments for it to show up and once it was dry the colors were really vibrant. But trying to have the boys slow down and wait was pretty much impossible to do and I gave up after several minutes. With that said, if you have a concrete walk that isn't the super smooth concrete, I would keep with the 1:2 ratio.
The cool thing about this project is that the ratio doesn't have to be perfect. As in, your preschooler can do it himself and the paint comes out just as good or better then yours. Evan was having a ball "measuring" tablespoons and even though his accuracy is not that great yet, his paint turned out fine. The mess on the other hand...
And the quote of the day was after Evan accidentally dropped his bowl of cornstarch all over the table and floor. Have you ever noticed how cornstarch GOES EVERYWHERE?
"It's okay Mom, when you do art projects, you're supposed to get messy!"
Guess who had to clean the mess up?
