6. Vibrant Salt-Painted Rainbow Swirls
What This Idea Means
Salt painting is an engaging science-meets-art project. Glue lines are coated in table salt and then touched with liquid watercolors. The salt instantly absorbs the colored water through capillary action, creating glowing, dimensional art.
How to Make It
- Draw with Glue: On a thick piece of cardstock or watercolor paper, squeeze liquid white school glue in swirling rainbow paths, mandala patterns, or ocean waves.
- Coat with Salt: Completely cover the wet glue lines with table salt. Tilt the paper over a tray to shake off all loose, excess salt.
- Apply Paint: Dip a soft paint brush into diluted liquid watercolor or food coloring mixed with water. Touch the wet brush tip gently to the salt line—watch the color magically travel down the salt path!
- Dry Completely: Allow the artwork to air dry overnight without touching the raised salt ridges.
Tips and Variations
- Tips: Use heavy cardstock or canvas boards; standard copy paper will warp and soak through from the moisture.
- Variations: Try making neon space scenes, name sign letters, or jellyfish tentacles using this technique.
Materials Needed
- Heavy watercolor paper or cardstock
- White liquid school glue
