The kids and I made some art today with salt and food coloring using a combination of techniques (salt painting, drip painting).
The materials were all things I had around the house - salt, food coloring, contact paper, droppers, and q-tips:
I put the contact paper (sticky-side up) in a tray, and invited the girls to shake salt on it:
I shook off the excess salt. Then the girls dripped water colored with food-coloring onto the contact paper using q-tips, cotton balls, and medicine droppers:
Occasionally, I helped the girls pick up one side and let the drops of color run down the sheet. The final effect was really interesting:
This is one of those art projects that doesn't quite create a final product that can be displayed easily (I think it would be too messy to hang up), but the process was a lot of fun for the kids and they loved creating something beautiful.
