I found this idea in one of the Penny Whistle party books. It sounds like a fun science project.
Creating Natural Dyes
For Yellow: use saffron, daffodils, yellow onion skins, or crocuses.
For Green: use broccoli, spinach, moss, rhubarb, or grass.
For Blue: use blueberries.
For Brown: use coffee, tea, walnut shells, or plums.
For Red: use beets or red cabbage.
Wash and chop the raw materials chosen to produce one color and place in a nonreactive pot (stainless steel, heatproof glass, or enamel). Cover with water. Boil for at least 5 minutes or longer to produce darker colors. Strain through a colander lined with cheesecloth or a clean rag. Cool the dye, then gently dip your hard-boiled or blown-out eggs into the solution for a few minutes or until you've reached the desired color intensity.
How To Blow Out An Egg
Prick both ends with an egg pick or a heated pin or needle. Hold the egg over a bowl and blow from one end just as you would blow up a balloon until all the liquid is emptied.
Happy Easter!
