To make bath paint, gather corn starch, liquid body soap, food coloring and some containers. I found small round plastic containers that hold approximately 6 teaspoons, but any type of container will work.
Mix equal parts of corn starch and liquid soap. My daughter and I mixed two teaspoons of corn starch and two teaspoons of liquid soap to create each color.
We used a very mild organic castile baby soap.
Mix the corn starch and soap together.
Add one or two drops of food coloring to the mixture. If you use more than one or two drops of food coloring, the paint may stain the grout in your bathtub.
To add another sensory element to the bath paints, we added a couple of drops of essential oils to the mixtures.
We blended blue + red to make purple and red + yellow to make orange. We added tea tree oil to the green paint, lemon oil to the yellow paint, tangerine oil to the orange paint, rose oil to the red paint, geranium oil to the blue paint and lavender oil to the purple paint. Adding essential oils is not necessary.
The paints are ready! Grab a paintbrush and fill the bathtub!
The consistency of the paint is great. Sophia started painting with the paintbrush and ended up painting with her fingers.
After my daughter washed the paintbrushes in water and mixed more water into the paint containers, the paint began to thin and drip. We loved the designs that the paints created. Sophia wanted to recreate a "scene" from Alice in Wonderland. I love that Sophia can paint without having to use paper. And, at the same time, she's not limited by space.
All of the colors washed out except for the purple. I created a paste of lemon juice and corn starch and applied it to the grout with an old toothbrush. I left the mixture on for 30 minutes and the color came out. Even though it was extra work to clean up the purple paint, I would definitely do this activity again!
