My ten years ago to the baby boiled mixed eggs, not shaking, is the method of impact palm, one hand holding the egg, towards the other palm hit (remember: is to take the egg of the hand to hit the other palm, do not use the egg to hit, it will break the egg shell), a strong impact of the vibration generated by the force is far higher than the hand shaking, super simple. At the time it was because babies don't like egg yolks, so I came up with this idea.
Roughly Chen eggs dozen new eggs twenty or so times you can hear the inside of the egg bam, and then you can shake a few times or hands quickly rubbing rotating eggs.
Try not to puncture the eggshell to stir the egg, easy to overflow when cooking, but also easy to seep in bacteria.
