thank goodness for home made, food safe, watercolors!
The watercolor recipe is pretty much the same one you'll find everywhere, including Martha Stewart. But I'll put it here too:
Mix together 2 tbsp baking soda and 2 tbsp white vinegar until the fizzing stops.
Stir in 2 tbsp corn starch, and 1 tsp corn syrup.
This will make a very thick gloopy mixture. Carefully separate out into how many colors you want, and mix in a few drop of food coloring. Dry overnight or use right away.
The more food coloring you use, the brighter the colors, but the longer it will take to dry.
The resulting painting will be a bit powdery, but we don't really mind.
the Llama had a blast, and cleanup was relatively painless!
