Bring water to a boil and divide boiling water into five different bowls. Add 1 teaspoon vinegar and 10 - 20 drops of food coloring to each cup to achieve desired color. Stir to mix.
Place an egg in the dye for about 5 minutes or until desired strength of color is achieved.
Using a slotted spoon, wire egg dipper or tongs, remove egg from the coloring and let dry on a paper towel.
Repeat until all eggs are dyed.
