DIY Science Experiment #19 - Easter eggs with natural dyes!

With Easter approaching, try a more eco friendly method to dyeing eggs with the help of a little science!

Materials: Hard boiled eggs, pan, water, vinegar, colorful kitchen items to create natural dyes

Ideas for kitchen items: Brown - strong coffee, Purple - blueberries, Green - spinach leaves, Blue - red cabbage, Orange - yellow onion skins, Yellow - grated carrots, Pink - beets or cranberries

  1. After you have chosen a dye color and gathered your materials, chop or grate the food (fruit or vegetable) that you are using. If you are using liquids, pour several cups of the liquid. 
  2. Add 1 cup of water and 2-3 teaspoons of vinegar for every handful of chopped/grated fruit or vegetable, or add 1 part vinegar to 3 parts of liquid.
  3. Put the mixture in a saucepan and bring to a boil for 5 minutes. 
  4. Strain the dye and let it cool before submerging the hard boiled eggs.
  5. Leave overnight for rich color.

How does it work? The vinegar acts as a mordant. A mordant is a substance that reacts with the dye, changing its chemical bonds so that the dye attaches to the object being dyed. A mordant can also change the color of a dye - so don’t be shy to experiment!
