to blow out the yolk first you need a needle and a straw. first you poke a hole through both the top and bottom make sure you pop the yolk in the center with the needle this will make it easier to blow the yolk out. put the straw to the top of the egg and blow untill the egg is empty(if you would like you can rinse the egg out you can)
Step 2: Painting eggs
now the rest is up to you paint the eggs however you want, get creative.
Step 3: Why this is better
it has been proven that hiding eggs lets the dirt and bacteria inside of the yolk and white with this method the yolk is out before the egg is hidden so bacteria can't infest the egg. and with this way you can "have your egg and eat it too."
