2. Extract the contents with a syringe or compressed air.

The one "specialized" piece of equipment that you definitely need for this project is a wide-bore syringe. It is important to fully remove the contents. If you do not, you'll end up with a big and distracting blob of yolk in the middle of your finished omelette. This syringe has holes in the side, so it can't suck up the contents all the way to the bottom. Turn the egg upside down, and gently push air into it. The egg contents make an air seal against the needle, the egg pressurizes, and the contents will squeeze out alongside the needle. Be careful not to overpressurize the egg, or it will burst. A low-end aquarium pump with a soccer-ball needle can also be used to extract the contents this way.
