Here is how to make colored rice or colored pasta for a variety of activities:
1. Fill a bowl ½ full of hot water, add a touch of vinegar, and food coloring.
2. Add the rice or pasta and submerge in water.
3. Let it soak for 30 to 45 minutes, while stirring every 10 minutes to assure even color, and to keep it from clumping.
4. Drain water from bowl, poor pasta onto a paper plate lined with a couple paper towels to dry. Once dry, break apart any clumps, and you will have colored rice or pasta to use for activities.
