Before you begin: Set up a work area. An old cookie tray works great to contain the mess and make clean-up easier.
Draw a simple design using school glue. Lines work better than large blobs.
Sprinkle table salt over all the glue lines. A tray underneath will help catch extra salt.
Carefully move the black paper so the salt fully covers the glue. Gently shake off excess.
Dip a small brush or pipette into watercolor paint and touch the salt lines. Watch the colors spread and blend.
Continue adding color to all glue and salt lines until you’re happy with the design. Let it dry completely.
Kids can paint areas that don’t touch the salt lines to add even more color and creativity.
