CANNON BALLS!!!
It was necessary to keep a good supply of cannon balls near the
cannon on old war ships. But how to prevent them from rolling about
the deck was a major problem. The best storage method devised was to
stack them as a square based pyramid, with one ball on top, resting on
four, resting on nine, which rested on sixteen. Thus, a supply of 30
cannon balls could be stacked in a small area right next to the
cannon. There was only one problem -- how to prevent the bottom layer
from sliding/rolling from under the others.
Answer
The solution was a metal plate with 16 round dimples, called, for
reasons unknown, a Monkey. But if this plate were made of iron, the
iron balls quickly rusted to it. The solution to the rusting problem
was to make the plates of brass - hence, Brass Monkeys.
Few landlubbers realize that brass contracts more, and more rapidly
than iron when chilled. Consequently, when the temperature dropped too
far, the brass indentations would shrink so much that the iron cannon
balls would come right off the monkey.
Thus, it was quite literally, cold enough to freeze the balls off a
brass monkey. And all this time, you thought that it was just a vulgar
expression, didn't you?
You must send this fabulous bit of historical
knowledge to at least a few uneducated friends.
