Grab some watercolor paints, a couple of brushes, some watercolor paper, and play around with art.
How does it work? The salt prevents the paper from absorbing the pigment, so depending on how big the crystals are, or how much you use, you can get different textures. Here's a fun video showing the process.
Let them dry overnight, and then peel off the plastic. (You can save the plastic for another painting) Here's a video showing the process (with acrylics) and a longer one showing a variety of plastic techniques.
This is National Arts in Education week. Visit us tomorrow and every day this week for arts activities and book reviews.
