Window Art with Craft Foam

I have been trying to come up with ideas to keep my kids entertained while their Dad's away and this is another one of my projects I found online and made. So easy and fun. All you need are scissors, craft foam, water, a window, and a spray bottle or paint brush. Cut shapes out of craft foam and let your kids paint water or spray it on a window. Then they can stick the foam onto the window to make cool pictures. I used my Cricut to help with some of the shapes and this is what the kiddos came up with.
Notice how dirty my window is?
