In a small nonporous (glass) bowl place 1 pkg of rice. Dissolve a small amount of paste food coloring in about 2 Tablespoons of tap water. (If you are not using paste food coloring use more food coloring and less water to get your desired color.) stir the rice until fully coated with color. Pour out onto a paper towel to dry. stir periodically. If you use a cloth towel the dye may cause permanent staining, so use a paper towel or just let in dry in the bowl and you will need to stir it more often. Store in a airtight container. Let your imagination run wild at all the uses for this colorful medium.
