  • Hard-boiled Eggs
  • Oil (Vegetable, Canola, or any oil will work)
  • Food Coloring (Assorted Colors)
  • Vinegar
  • Water
  • Plastic Cups
  • Small Bowls


STEP 1: Place 1 cup of very hot water in a plastic cup, add 3-4 drops of food coloring and 1 tsp of vinegar. Mix well. Repeat with other colors.


STEP 2: Add the eggs in each cup and let sit for about 3 minutes. Remove and set on paper towels.


STEP 3: In each bowl, add about 1 inch of water. You only want about ½ of the egg to be covered. Next, add 1 Tablespoon of oil to each bowl and 6-8 drops of food coloring.


STEP 4: Place one egg into each bowl. With a spoon, spoon the water/oil mixture over the egg and let sit for about 3-4 minutes. Then roll the egg so it turns over and let sit for another 3-4 minutes.

The Simple Science of Dyed Eggs With Oil And Vinegar

Your good old food coloring from the grocery is an acid-base dye and the vinegar traditionally used to dye eggs helps the food coloring to bond to the eggshell.

We know that oil is less dense than water thanks to some other nifty science projects like our homemade lava lamp. You will notice the oil floats on top in this activity too.

When you put the egg in the final colored oil mixture, the oil keeps parts of the egg from bonding with the food coloring giving it a marbled appearance.

These marbleized oil and vinegar Easter eggs remind me of space or galaxy themes. They are perfect for space enthusiasts and for junior scientists everywhere!
