Corn starch, water, food coloring, painting sponges/ really thick brushes (at the dollar store!), a muffin pan (pick up one at a thrift shop for 50 cents!)
Mix equal parts corn starch and water. You want the paint to be pretty runny so that it spreads onto the sidewalk or driveway easily. Pour the mixture into the muffin pan and color however you want. That's it. There is nothing you can do to mess this up. Nothing. Because if there was, I would have found a way. But there just isn't a way. Easy peasy.
Prep time is like 90 seconds. So you can do this on the fly no problem.
Take it outside and have fun! Note: grungy clothes a must! This is a bit sloppy and drippy. It will most definitely get onto their clothes. I mean, I don't want to live in a world of only clean painting, do you?
This was a BIG hit with these two silly people. Here are some highlights.
Oh and total cost for supplies that will last all summer?
6 bucks, dude.
