Belated Passover/Easter Science Activity

Here's an activity that I used to do with my kids when they were young. You will need
Raw Eggs
Coffee Grounds (available for free from most coffee shops) NOTE: coffee grounds not ground coffee.
Onion Skins
Olive Oil
Salt, Pepper
Roasting Pan with lid

1. Put a layer of onion skins in the bottom of a heavy roasting pan.
2. Gently place an egg into the onion skins.
3. Drizzle olive oil onto the eggs. If you wish you can even use a clean paint brush to paint on a design using the olive oil.
4. Sprinkle salt and pepper over the eggs.
5. Use your hand to scatter the dry coffee grounds over the eggs. Cover the eggs with another layer of onion skins.
6. Have an adult put the roaster in the over, and add enough water to cover the eggs. Have the adult cover the roaster with a lid and turn the oven on to 225 degrees.
7. Leave the roaster in the oven overnight.
8. Wash your hands with soap and water after touching the eggs.

In the morning have an adult use oven mitts to remove the roaster from the oven. Using a slotted spoon, remove each egg from the onion skins and rinse in cold water. The eggs have turned a rich, brown color, with blotches of bright yellow and streaks of white. When you remove the shell, you will find the egg is a mocha color. Presuming you don't have any food allergies, eat the egg for breakfast. Does it taste like coffee?
