If you want to decorate Easter eggs that can last well beyond Easter, you need to blow out the eggs first. While it sounds hard and complicated, it is pretty easy to do once you know how and get the hang of it.
First, leave the egg in the carton so it won’t move around as you try to piece a hole. Use a needle or pin (a safety pin will do in a pinch) and pole a hole in the top of the egg (the narrow end). You can also use a small nail (such as ones that are used with the small picture hangers) to gently tap a hole in the top of the egg.
Remove the pin/nail and gently insert a wooden skewer (such as what you would use to barbeque kabobs). Swish the skewer up and down to break up the yolk (otherwise the yolk stays intact and you can’t blow it out).
Gently push through to the bottom of the egg, carefully pushing through the bottom of the egg. You should have a hole in the top and the bottom. Insert a small straw (the small coffee stirrers work great or fold a larger straw to fit) and blow the entire inside of the egg out. If your kids do this part make sure they don’t suck the egg out, since it is obviously raw egg!
