Craft Project: Homemade Puffy Paint
Have not tried making it with all-purpose flour and baking soda. But I am sure it would work because thats what is in the self-rising flour. Might have to experiment with the measurements though.
Liquid Sidewalk Chalk
The colors do not stain the concrete, the colors are much brighter before they go onto the concrete. And then they wash off very easily, just as regular chalk does! :)
