, when we've boiled
up a few dozen eggs
ing, someone accidently mixes the hard-boiled eggs with the uncooked
ones. This can be a sticky problem come the next morning, when kiddies
who expect eggy goodness
only get eggy goo
Anyway, to determine if that egg is cooked, all you have to do is lay the egg over on its side and spin it quickly. Let it spin for a few seconds, then using your fingertips, stop it and release. If the egg starts slowly spinning again, it is raw. This is because the liquid goo inside is still in motion, and when you stop and release it, the yolk causes the egg to return to spinning, albeit slowly.
If it stops and does not start spinning, it's cooked enough so the goo is not so gooey anymore.
