In a bowl, mix together 1/2 cup boiling water, 1 teaspoon vinegar, 20 drops Adams Food Color.
Dip egg in dye color and let sit until desired color intensity is reached. Remove egg and let dry on paper towel. Take a small square of foil (enough to wrap around the egg) and crumble it up then open it up flat. Over a paper towel, Use a few drops of color dye of another color and place in the center of the foil. Place the egg in the center and wrap completely with the foil. Some of the color may drip out. Let this sit for a few minutes. Unwrap the egg and pat with a paper towel to dry. Your egg now has a second color pattern!
