How to Blown Out an Egg

Poke two holes in it, one at either end, lengthwise. The hole for the egg contents to exit should be about a quarter of an inch in diameter. The hole you blow into can be smaller.First, poke a hole with a thick sharp sewing needle, pushing through the shell gently with very light force. You do not want to break the eggshell.
Create the second hole in the other end of the egg.
It helps to make sure you puncture the yoke before trying to blow it out.
Hold the egg over the bowl, and blow into the top hole. Be sure your grasp on the egg is not too tight or it will crack.
Once you’ve emptied the shells you need to remove egg residue from the inside.
Fill a large bowl with warm water and a few drops of dish soap.
Submerge each shell to fill it with soapy water and shake. Let sit for five minutes, then drain the water.
Empty each eggshell and rinse well.
Set aside to air dry.
You can hide the hole by gluing on small bits of tissue paper that matches your decoration.
