Learn about the unique properties of salt as you make paintings using this household item!
Materials
- PVA school glue or craft glue
- Salt
- Food colouring of your choice
- Water
- White card-stock or watercolor paper
- Template for the shapes you’ll be painting
Directions
- Trace your template onto cardstock.
- Add glue to outline your shapes. Then add a good amount of salt onto the glue and carefully pour the excess off.
- Let the glue (and salt) dry.
- Mix a few tablespoons of water with your choice of food colouring to make your watercolour paint. Use a pipette to slowly drip the watercolour mixture onto the salt. Try not to drench the patterns but rather watch the salt soak up one droplet of colur at a time.
- Leave your salt painting to dry overnight, then display it in your home.
Spark Creative Learning!
- Notice how the water is absorbed and slowly moves throughout the pattern. You can even add drops of different colours and see what happens!
- Salt is a really useful product that has the ability to absorb moisture from its environment. Its ability to absorb water is what makes salt a good preservative. This property of absorption is called hygroscopy. Hygroscopic materials absorb both liquid water (the watercolour paint mixture) and water vapour in the air, creating a dehydrating effect.
