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
- 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.
- 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.
- Put the mixture in a saucepan and bring to a boil for 5 minutes.
- Strain the dye and let it cool before submerging the hard boiled eggs.
- 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!
