Liquid dish soap, white tempera paint, paintbrush, plastic wrap
Add a small amount of liquid dish soap to white tempera paint. Mix it thoroughly. Have your child paint pictures or designs on a window. Cover the windows with plastic wrap and let the paint sit overnight. The next day, remove the plastic wrap from the windows and you'll see your frosty "winter" window come to life! **By including the liquid detergent, the paint will come off your windows with a few sprays of glass cleaner.
