I would love to see a picture of this rainbow rice. Thanks for sharing the process!
Rainbow rice is one of Henry’s favorite sensory bins we have used it over and over again. To make it use one cup of dry rice + 1 tablespoon white vinegar and several squirts of food coloring. Combine them all in a ziplock bag and then let it dry on a paper plate! Repeat for each color you would like to use.
