There are many different ways to separate an egg yolk from the egg white. Egg separators are already on the market, but if you want to be frugal, you don't want to buy one. One method is to use its own shell, but there's a tendency that the yolk will break. Another is to use your clean hands, but it's kind of messy, right?
One fun trick is to use a plastic bottle. Press it close to the egg and it will vacuum the whole egg yolk in. Get your plate and press the bottle again to release the yolk.
