Place one egg in the middle of one coffee filter and wrap it tightly, bringing the excess coffee filter to the tip of the egg and securing it with a rubber band.
Get your food coloring and start with one color, putting one drop in random spots around the egg. Do this with as many colors as you like, however, I tend to use 4 different colors, the basic red, green, blue, and yellow is what I used for this recipe. Do this until the coffee filter around the egg is mostly filled with food coloring. It spreads, so a little goes a long way.
Leave the eggs to sit for 5 minutes,
Using rubber gloves if desired, gently unwrap the eggs and pat them dry with a paper towel.
Set them back in the egg carton to dry for about 5 minutes. Enjoy!
