Before you get started, here are some important things to do first!
- Fill up each child's water cup (half way)
- Open up the watercolor sets so they're ready to go
- Give each child a bottle of white glue and have them open it and make sure it works!
- (Pro-Tip) Drop a little water in each color of the watercolor sets to prime them for kids.
How do you make salt art?
The salt art process is super simple, which is why it's one of our favorites.
Here's what you do to make this simple salt art project:
- Draw your design with glue on the black (or colored) paper.
- Drop the paper in a cardboard box and cover the glue design with salt.
- Shake off the excess salt.
- Put the salt covered paper on a craft tray (or a baking pan)
- Paint the salt with watercolor paint! Touch the paint covered paintbrush gently to the salt as you paint the salt covered design.
- Once painted, let dry completely.
See! Wasn't that easy?
Do I need to let the salt and glue dry before I paint?
Nope! You don't need to let the salt and glue dry on your salt art project before you start painting. You can paint the salt/glue design as soon as you shake off the excess salt.
Once you're done painting, then let the salt art dry.
What is the science behind salt painting?
Salt art is a cool science and art activity! This salt art project teaches kids about absorption!
Salt is a hygroscopic substance that absorbs water. Hygroscopic means it attracts water from its surroundings.
When the watercolors touch the salt, the water is absorbed immediately (before the water can touch the glue) and leaves the paint on the salt.
Try This! Experiment with using more or less water as you paint and see what happens! Which one makes the color faster? Slower? Watch and see what happens!
In addition to using paint brushes, you can also use eye droppers for this art activity! Just squeeze colorful water onto the salt designs. Check it out in action here where we tried Spring Salt painting.
