This activity was a great way to keep my little ones' hands busy when it was too wet to go outside. While the clouds were gray, my kids were creating their own sunshine and rainbows and making shapes while mixing new colors. And, when they were done, my windows were "sparkling" with their extra soapy cleaning!
Gather all your materials. The first time we made these, we used bubble bath instead of dishwashing liquid and it worked great. We've also mixed our colors in ice cube trays and baby food jars, but I think the egg cartons make for the easiest clean up.
To make each color, we mixed equal parts dishwashing liquid and washable paint in each section of the egg carton.
My older children painted neighborhood scenes in the kitchen windows. They included houses with people and pets and even included scenery. We left the blinds up all day to enjoy our sunny pictures on a rainy day.
The next day, I set my oldest boys loose on the deck windows with their water guns and was amazed at how easily the paint came off. My boys are now asking to wash the windows for me all the time! The kitchen windows cleaned up easily with a warm wet towel and a quick spray of our vinegar window wash.
