If you’re looking for a fun, hands-on activity that blends science and art, salt painting is the perfect summer project! This is a great way to reuse leftover school supplies, spark creativity, and sneak in a little STEM learning while the kids are having a blast.
Salt painting uses salt’s ability to absorb water to create a fascinating texture and color effect. Kids get to see the science in action while making something beautiful!
What You’ll Need
- Summer-themed outline (free printable – download below)
- White glue
- Salt (table salt works perfectly)
- Watercolor paints
- Water
- Paintbrush or dropper
- Art Mat or tray or tablecloth (optional but makes clean up easier)

Instructions
- Print Your Design
Download and print the free salt paint summer-themed outline. You can choose from fun designs like beach scenes, ice cream cones, underwater creatures and more. - Trace with Glue
Using white glue, carefully trace the lines of your summer design. Don’t worry if it’s not perfect—this is all about having fun! - Add the Salt
Sprinkle salt generously over the glue so it’s completely covered. Gently shake off the excess. - Bring It to Life with Color
Dip your paintbrush or dropper in watercolor paint and lightly touch it to the salted glue lines. Watch as the color travels along the salt path! This is the science part—salt absorbs the water and spreads the color. - Let It Dry
Once your masterpiece is done, set it aside to dry completely.
The STEM Connection
This activity isn’t just pretty—it’s science in disguise! The salt absorbs the water from the paint through capillary action, drawing the color along with it. It’s a simple and fun way to introduce kids to concepts like absorption and how water moves through materials.
Why I Love Salt Painting

- Mess Factor: Manageable – Just put down an art mat, tray or tablecloth and cleanup is quick.
- Educational – Combines science and art for a well-rounded activity.
- Creative Freedom – Kids can choose their colors and see unique results every time.
