How do I dye rice for projects?

A friend dyed rice with food colouring, leaving the rice to start in a tray. It created pastel colours 😀

Put the rice in a zip lock bag

This is how I did it for my Pre-K classes: Put the rice in a ziplock bag (quart size) add about 3-5 drops food coloring and close the bag making sure the bag is tightly sealed. Now, mix it up by hand, add more drops if you need the rice to be more intense. Once the rice is the color you want spread it out on a cooking sheet to dry.
