This is about 'egg magic.' When you make a egg for the pan, you basically crack the shell and try to put the egg, yolk intact, into the pan. This I found out from witches, it is either a success or a neutral thing, as in nothing bad will happen, or, it breaks, indicating failure or such. I have often wondered how this works, let me try to decipher it for us?
If we were to observe it requires confidence to break the shell properly, where we need to apply force to the shell breaking to get the opening big enough for the yolk not to get clipped on the shell. Then, we will understand that we can use confidence upon question regarding our true nature, a sign that we are committed to our family as a provider of resources, or, a good child for the little ones, or, that it is a sign of success to come. This is where the faeries inhibit the shell to to provide obstacles of life, and, other faeries, where they will show you the make up fate is against you, as they control fate.
Therefore, at surface level;
 The true signs are based on confidence with the matter, that you know you can, and that you do it right as a test of your confidence to commit to it, that you feel you can, and therefore when the task rises, you know you can. In western culture, an example could be like a love question, like, does that girl like me back, and, as a third world question, it could be that you ask if you will make your wife pregnant soon, of course.
So, at lore level;
 To answer a question other than something of what you can do, or, a question about life, you will notice that the resistance and obstacles are shown to you by the shape of the shell. This is because the faeries collect and provide resistance where necessary,and erode at others with support for your cause.
Thus at scientific level;
 The shell is broken by your confidence with the matter, and, your timing, and your body language, and, your destiny. Your mood affects how much force comes down on the shell, and, that will be influenced by your mental, physical and emotional influence on the action. Mentally, you will choose your angle, mathematically, physically, your reflexes will be tested, and, emotionally, you need to handle the pressure. This is founded upon the angle you strike the egg at, the amount of force and the energy relays fro your own fingers to the shell. This can be further explained by the synergy between the three, and, the query is based on the inception of the mind, channelled to the fingers, influenced by the soul. This will come down to a clean break, where a bone will break cleanly if struck correctly. That is what you are hoping for, yes? A fracture would produce some varied resistance, and a bruise would be where you get that membrane on your egg, this is you dominating the problem, of course. This is founded on your ability to deliver, to the problem based on your skills and know how, and, all the essence of you collecting to tackle the problem.
Not hocus pocus after all, hey?
