Pour 1 cup of rice into each of the 2 ziplock freezer baggie (1 cup in each baggy).
Add blue food coloring to one, close the ziplock and mix it by massaging the rice through the baggie until the desired shade was reached. Keep adding a few drops of food coloring each time until it gets to the desired shade.
Repeat this same step with the red color and the other baggie. A deep red color may take more food coloring than blue.
Start with the red rice, pour 1/3 cup of the red colored rice into the vase and level it out. Add the undyed white rice and top with the blue colored rice.
Add a votive or tea candle on top.
Using the baggies makes absolutely no mess and no cleanup, just throw them away.
