Cool Epsom Salt Painting Craft

Who’s up for some kids’ science? With the kids out of school for the break and many of you snowed in, here’s a fun activity to bring crystals inside–but not the cold. Wow your kids with Epsom Salt Painting. In the beginning the colors look like watercolors, but as the paint dries the kiddos get a fun crystal surprise!

It doesn’t take many materials to make this fun project, but it may get a little messy. Ready to try it? Let’s get started.

Materials:

• Heavy paper (lightweight paper will curl up as the paint dries)
• Epsom Salt
• Water
• Food coloring (optional)
• Paint brushes of various sizes (the solution will wash out of the brushes, but I still wouldn’t use your best brushes)
• Small jars or plastic cups

Directions for white paint:

Pour one cup of boiling water into your jar or plastic cup.
Add 1 cup of epsom salt, and stir until it completely dissolves.
Paint your designs onto dark-colored heavy paper.

Directions for colored paint:

Pour one cup of boiling water into each of your containers.
Add a few drops of food coloring to each container. (Keep adding color until you like the result.)
Add 1 cup of epsom salt to each container and stir until dissolved.
Paint your designs on white or colored paper. Experiment!

We originally planned this activity to go with our Frozen party, so we definitely had snowflakes on the brain! The more we painted, the more we tried new things. As we painted, we discovered some cool things. We won’t tell you about all of them, though, because it’s fun to discover them for yourself. Here are some things to think about and try as you paint and experiment:

• Why do you think the clear paint turns white when it dries?
• What will happen if you paint on paper that has a texture?
• Can you make paint bubbles that sit on top of the paper? (See the image above.)
• Why do you think the colored paint dries shiny and sparkly, while the white paint does not?
• Why do you think the thin paper curls as the paint dries?
• Why do you think the paint gets thicker as the water cools down?
• Why do you think the paintbrush gets clogged up the longer you paint?

I hope you and your kiddos have a lot of fun! Above is my favorite effect. The paint got shiny and puffy as it dried on this colored printer paper. (So cool!)

This was a pretty fun project to do with the kids. I had a great time joining the girls and doing some paining, too! It’s definitely nice to let the dishes stay in the sink, forget about folding laundry, and sit down and enjoy some creative time with the kids. Try it!
