New-laid Eggs
Here is a very handy method of discovering whether an egg is fresh or not.
Pass an elastic band around the egg, and hang it upon a wire, as shown in [Fig. 19]. Twist the egg and band round several times, and then release it, when the band will rapidly untwist with the egg. If the latter be quite fresh, it will stop almost immediately, but if it happens to be rather older than is desirable, it will twist and untwist, reversing several times before it finally comes to rest. This applies to eggs which have been boiled—indeed to any egg that is “set.”
