How to Crack an egg so you can preserve the shell

Learn how to crack an egg so that you can preserve the shell in simple steps. First take an egg and a butter knife and you have to make a hole at its top. To make the hole gently tap the top of the egg to make a crack. Now insert the knife in the crack and peel its top out. Pour the egg yolk in a container and rinse the shell several times with hot water. Spray an anti-bacterial spray to kill any germs in it and let it dry for sometime with its hole facing downwards.
