We have been sick a lot in the last few weeks and this mess free take on finger painting has been one of our favorite arty activities!
Tape three sides of a large ziplock onto a smooth surface, leaving the opening untaped. Any smooth surface will work, though we love using a window. The light passing through adds a unique element as the paint moves between being opaque and transparent. Add tempera paint to the ziplock. I recommend using two or more colors, so your kiddo can watch the colors swirl and mix. After paint is added, seal the ziplock and tape down. Squish and smoosh away! The bags can be saved and used again!
