Get one coffee filter out and put an egg in the middle of it. Wrap it tightly twisting the top and secure it with a rubberband.
Get rubber/plastic gloves on if you don't want your hands stained!
Grab your food coloring bottles and make little drops all over the coffee filter. Use one color at a time. The colors will spread a bit so you don't need too much.
Place the egg on a cookie sheet (or whatever surface you don't want stained) and let it sit for 4-5 minutes.
Carefully unwrap the eggs and use a paper towel to pat them dry.
Put the eggs in an egg carton and let dry for 10-15 minutes.
