Do Penguins Have Knees? (9 page)
What do certain firearms, heroin, and milk cartons have in common? Possession of each may be punishable by law. Although the wording above is used in California, many states forbid the unauthorized use of milk cartons.
Why the fuss? To get the answer, we contacted our favorite dairy Imponderables solver, Bruce Snow, recently retired from the Dairylea Cooperative in New York. If you wish to retain your faith in humanity, you may want to skip this explanation:
For more years than I care to remember, the milk dealers in New York (and other urban areas) lost several million dollars a year on purloined plastic milk cases. Never in the history of man has anything been invented for which so many uses have been found: bookcases; sidewalk flower displays; tool chests; album storage; toy boxes; transport cases for miscellanea; step stools, etc.,
ad infinitum
.
It finally got so bad that milk dealers petitioned their legislators to make possession of a dealer’s milk case illegal, subject to a fine. The dealer must have his name on the case, by law.
Theft wasn’t all the dealers were contending with. Supermarkets, which daily received thousands of cases around New York, were profligate in their use of plastic cases [which currently cost $2.50 or more] to build displays, cart trash, and carry stuff home. Why not? It didn’t cost them anything.
Now, however, the New York State law requires that markets must account for all cases to their milk suppliers. They are required by law to pay $2.00 for every case unaccounted for. Consequently, there is now much stricter control over the cases.
As a final note, it was discovered by some city milk dealers that shipments of new cases were being stolen, sent to plastic recyclers for some amount of money, to reappear as any one of a vast multitude of plastic gewgaws. All in all, it was a very big rathole through which a big piece of milk-generated money (ultimately from consumers) was being lost. The law has not eliminated all theft, but it has sharply reduced the problem.
The great irony, of course, is that the milk carton laws turn the tables on retailers. Supermarkets, often so reluctant to process recycled bottles and cans, now must do the same thing themselves, further proof that recycling efforts seem to work only when strong financial incentives exist.

Why
Does Shampoo Lather So Much Better on the Second Application?
Even if our hands and hair are already wet, we can’t seem to get a healthy lather on the first try when we shampoo our hair. But after we rinse, the shampoo foams up like crazy. Why is lather more luxuriant the second time around?
Evidently, it’s because we have greasy hair, according to Dr. John E. Corbett, vice-president of technology at Clairol:
In the first shampoo application, the lather is suppressed by the oils in the hair. When the oils are rinsed off [by the first application], the shampoo lathers much better on the second application.

Even cigarettes without filters don’t burn quickly. If the shredded tobacco is packed tightly enough, not enough oxygen is available to feed the combustion process. The degree of porosity of the paper surrounding the tobacco rod can also regulate the degree of burn.
On a filter cigarette, however, an extra impediment is placed on the combustion process; luckily, it is not asbestos. Mary Ann Usrey, of R. J. Reynolds, explains:
The filter is attached to the tobacco rod by a special “tipping” paper which is essentially non-porous. This paper acts to extinguish the burning coal by significantly reducing the available oxygen. So, in effect, there
is
a barrier between the tobacco and the filter, but it is
around
the cigarette, not actually between the tobacco and the filter in the interior of the cigarette.

What
Are You Hearing When You Shake a Light Bulb?
Would you believe the ocean? We didn’t think so.
Actually, what you are hearing depends upon whether you are shaking a functional or a burned-out bulb. If you are shaking a newish, functioning bulb, chances are you are hearing the delightful sound of loose tungsten particles left over in the bulb’s glass envelope during its manufacturing process.
According to Peter Wulff, editor of
Home Lighting
&
Accessories
, these loose particles don’t affect the bulb’s operation or lifespan. Wulff adds that although the tungsten particles aren’t left in the bulb deliberately, at one time manufacturers of high-wattage tungsten halogen bulbs did leave such residue: “Occasionally, it was recommended that after use and after the bulb cooled, the bulb should be turned upside down and then shaken to allow the loose particles to clean the inside of the glass.”
But today if you hear something jangling around, chances are that you are shaking a burned-out bulb. In fact, this is the way most consumers determine whether a bulb is “dead.” Richard H. Dowhan, of GTE Products, told
Imponderables
that in this case you are hearing particles of a broken filament, “the most common type of bulb failure.” Barring the rare case of loose tungsten particles inside the bulb, Dowhan says “you should hear nothing when you shake a light bulb that is still capable of lighting.”

Why
Do Fluorescent Lights Make a Plinking Noise When You Turn Them On?
We went to Peter Wulff again for our answer. Older fluorescent fixtures used a “preheat system,” which featured a bimetallic starter (the small, round, silver piece). Wulff told us that inside the starter is a bimetallic switch which “pings” when energized. Newer fluorescent systems, such as the “preheat” or “rapid start,” are rendering the “ping” a relic of our nostalgic past.

Why
Do Cats Like So Much to Be Scratched Behind the Ears?
Most cats like to be scratched for the same reason that most humans like to be massaged: It feels good. According to veterinarian John E. Saidla, assistant director of the Cornell Feline Health Center,
Most cats like to have their total bodies rubbed or stroked by humans. A cat’s skin is chock full of nerve endings, making your stroking a sensual experience.
But
our
skin is full of nerve endings, and not too many of us start wiggling our legs with delight when we’re scratched behind the ears. But then again, unlike cats, we don’t tend to have ear mites. Dr. Saidla explains:
Most cats harbor very few mites, while others have huge infections that are causing serious clinical problems. The mite in the ear canal burrows into the layers of skin lining the ear canal. The cat is allergic, or at least, reacts to the feces and enzymes the mite produces, resulting in pruritus or itching. When the owner rubs the skin behind the ear, it feels good and the cat responds appreciatively.

Why
Aren’t There Plums in Plum Pudding? And Why Is It Called a Pudding Rather Than a Cake?
Even though it contains flour and is as sweet and rich as any cake, plum pudding cannot be classified as a cake because it contains no leavening and is not baked, but steamed.
Besides flour, plum pudding contains suet, sugar, and spices and is studded with raisins and currants. In early America, both raisins and currants were referred to as “plums” or “plumbs.” And presumably because the raisins and currants were the only visually identifiable ingredients in the dessert (which traditionally was served after the pumpkin pie at Thanksgiving), the nickname stuck.
Come to think of it, plum pudding isn’t the only weirdly named dessert served at Thanksgiving. We used to ask our parents where the meat was in mincemeat pie.

What
Do the Little Red Letter and Number Stamped on the Back of My Envelope Mean?
When the arm of the United States Postal System’s Multi-Position Letter Sort Machine (or, as we close friends like to call it, MPLSM) picks up an envelope, it automatically stamps a letter and number on the back. The letter identifies which MPLSM processes the piece, and the number singles out which console on the machine, and thus which MPLSM operator, handles the piece.
This code has nothing to do with delivering the letter. The code is simply a way for the USPS to identify when a particular machine, or its operator, is malfunctioning. In other words, the A4 on the back of your envelope is the equivalent of the “Inspected by 8” label you sometimes find in the pocket of your new jacket.
Although it is our experience that most of the MPLSM codes are red, a casual glance at our voluminous mail indicates that brown and purple are popular, too. Frank P. Brennan, Jr., general manager of media relations for the USPS, says that each tour or shift has its own color.
Not every letter is processed by a MPLSM; increasingly, the USPS is relying on optical scanners. Scanners may be faster than MPLSMs, but without that red code, they can’t be held as accountable as MPLSMs when they screw up, either.

Do Owners or Handlers Use the Word “Sic” to Instruct a Dog to “Get Him”?

World magazine was kind enough to print our query about this Imponderable in their June 1990 issue. We were soon inundated with letters from dog lovers, the most comprehensive of which came from Fred Lanting, of the German Shepherd Dog Club of America:
