Boil the eggs and let them cool to room temperature.
You may want to use disposable gloves, and put some wax paper, or something on the table/counter tops.
Keep the empty egg cartons to store your eggs.
You can use a baking dish, shallow pan. Fill it with whipped cream, or cool whip.
Add two to four colors (we used neon food coloring) and then swirl with a toothpick. Please be careful not to add to many you will end up with a gray, or brown color.
Place the cooled eggs in the whipped cream mixture. Let the eggs sit for 10 to 20 minutes. The longer they set the darker the colors.
Wash cream off with water. The colors will stay.
