Why is vinegar used in dyeing eggs?

Answer

Hard-boiled eggs can be dyed for Easter using simple food coloring and vinegar. The vinegar is there to make a weak acid solution, which breaks down the waxy barrier on the egg surface, allowing the dye to penetrate more deeply into the eggshell. You can dye the eggs without the vinegar, but the colors won't turn out quite as bright, and it will take longer to get the same amount of color.
