Homemade Sidewalk Paint

This is an environmentally friendly sidewalk paint. It washes off very easily and will not harm plumbing or plants...cornstarch is all natural and biodegradable. It is also very inexpensive!

1/4 cup cornstarch
1/4 cup water
6 to 8 drops of food coloring

Directions:

Put cornstarch in a small plastic bowl and gradually stir in the cold water. Add your desired food coloring and stir. If the paint still feels to dry, just add a little more water until you get the consistency you prefer. (I didn't need to add any more water to mine)
Repeat the process to create different colors.
