Tools: Small plastic bottle, two plates, a bowl, and a couple eggs.
1.Get a small bottle with a moderately wide neck, so egg will not fall out.
2.Crack egg over first plate.
3.Squeeze bottle gently over egg. Be sure not to press the bottle on the egg yolk too hard, or the membrane will break.
4.Gently release the grip on the bottle as the yolk is drawn inside.
5.Repeat as needed.
