Soak the hard-boiled eggs in vinegar for two minutes. NOTE: This helps to make the colors more vibrant.
Take the whip cream (or shaving cream) and spread it into a pan or dish with sides.
Add drops of food coloring to the whip cream. Use as many drops and / or colors as desired.
Using a toothpick, fork, or knife swirl the food coloring around. Be careful to not combine the colors too much.
Place an egg in the Cool Whip and food coloring and roll using a spoon. One roll is recommended so that the colors don’t mix. Repeat with as many eggs as you choose.
Let the eggs set in the cool whip mixture covered in the color for 10-30 minutes. This allows the egg to absorb the food coloring.
Rinse the eggs with cool water and then dry!
Repeat with different colors and combinations.
