• Farmington, Maine, holds a parade on the first Saturday in December to honor Chester Greenwood, the boy who invented earmuffs.
• The woolen swimsuits that people wore at the turn of the 20th century weighed about 20 pounds when wet.
• Men carried purses before women did. The purses were called “pockets.” But because they hung from a string and could be easily stolen, eventually they were sewn inside clothing and—
voilà!
—became the pockets we can’t live without today.
• The first knit socks were discovered in Egyptian tombs of the 3rd-6th centuries A.D.
Q:
If you see a moose kneeling, what’s he doing?
A:
Eating. He can’t graze like a cow—his neck is too short and his legs are too long—so he has to kneel to eat.
Q:
If it has one horn, it’s from Africa; if it has two horns, it’s from India. What is it?
A:
A rhino.
Q:
Dogs are color-blind when it comes to seeing green and red, so how do seeing-eye dogs tell the difference between a red traffic light and a green one?
A:
They don’t. Instead, they watch the flow of traffic to see when it’s safe to cross.
Q:
Are zebras white with black stripes or vice versa?
A:
Scientists are still arguing about it.
Q:
What kind of fish is a Portuguese Man-of-War?
A:
It’s not actually a fish—it’s an invertebrate, meaning it doesn’t have a backbone like a true fish does. It’s related to both jellyfish and coral. The Man-of-War isn’t really even one single animal: It’s a colony of four parts that work together to survive.
• Greenland isn’t very green—in fact, it’s almost entirely covered with snow and ice. Viking explorers named it Greenland to lure settlers there.
• It’s the yellow soil beneath China’s Yellow River that gave it its name.
• The Dead Sea really is dead. Located at the end of the Jordan River, the sea’s water evaporates and leaves heavy deposits of minerals, which makes it uninhabitable and much saltier than an ocean.
• The Ivory Coast in northwest Africa was once the center of the ivory trade for Europeans, who hunted elephants for their valuable ivory tusks.
• Why is the Red Sea called “red”? It could be from the occasional red algae that appear there, or it could have been named for nearby red mountains. Some people say it’s actually a mistranslation of “Reed Sea.”
• Huh? The Canary Islands were named for the wild dogs that lived there. You’ve heard dogs called “canines”?
Canis
is Latin for “dog”—and the ancient Romans named the islands.
• Ireland is called the Emerald Isle because of its green countryside, not because of any actual emeralds.
• Moscow’s Red Square isn’t red: It was so named because
red
means “beautiful” in Russian.

• The world’s tallest roller coaster, Kingda Ka at Great Adventure in New Jersey, reaches its peak at 456 feet. It’s the world’s fastest, too—clocked at 128 mph.
• A 14-year-old German boy built a 300-foot-long
working
roller coaster in his backyard over the summer of 2005…but local officials made him tear it down.

• The hurdles in the women’s 100-meter hurdle event are 33 inches high. In the men’s 400-meter hurdles, they’re 36 inches high. Which is only fair because on average, men are 3 inches taller than women.
• Old-time baseball player Hughie Jennings holds the records for being hit by the most pitches (287 times) and for being hit the most in a single season (51).

• Love cheese? You’ll probably eat more than a ton—2,000 pounds—of it in your lifetime.
• It takes 29 cups of milk to make one pound of butter.
• Butter’s yellow color comes from the beta-carotene in the grass that dairy cows eat. Butter is yellower in the summer, when grass is plentiful. In winter, it’s usually off-white.
• People added carrot juice to butter in the Middle Ages, thinking it made the color more attractive.
• Need something to cool off your mouth after eating spicy food? Try milk—it contains
casein
, a protein that soothes burning taste buds.
• Bad, but still good: Blue cheese was most likely discovered by accident centuries ago, when cheese was stored in caves. A batch of cheese probably got moldy, and some brave person decided to taste it anyway.
• Istanbul, Turkey, is the only city in the world located on two continents: Europe and Asia.
• Los Angeles’s full name—El Pueblo de Nuestra Señora la Reina de los Angeles de Porciuncula—can be abbreviated to 3.63% of its size: L.A.

• Sea World owns 25 orcas—55% of the worldwide total in captivity. And, by the way, they’re not killer “whales,” they’re a type of dolphin.

• Watch your hands: In 2004 a piranha was discovered living in a petting-zoo aquarium in Berlin, Germany.
• Jungle gym: Zookeepers in Anchorage, Alaska, installed a treadmill to help an elephant named Maggie lose some weight. The treadmill and a diet helped Maggie lose 1,000 pounds, down from 9,000.
• Zoo authorities in England sent a parrot into solitary confinement after the bird used some really bad language directed at two policemen, a mayor, and a priest. (They can’t figure out how he learned it.)
• About a month before St. Patrick’s Day in 2004, two polar bears in the Singapore Zoo turned green. A zoo spokesperson explained that it was because of harmless algae growing in their hollow hair shafts, and could be easily cured with a salt solution.
• The people who create sound effects for movies are called “Foley artists.” Sometimes they use very bizarre objects to find just the right sound, like snapping celery sticks to mimic the sound of bones being broken.

• The sound of the tornado in
Twister

• Superman’s home planet was named after the real element krypton, a gas that was discovered in 1898.
• Though it’s commonly thought to have an icky smell—kind of like rotten eggs—sulfur is nearly odorless. The stuff that smells bad is
hydrogen sulfide
, a gas that forms in sewers and swamps.
• Neon is colorless, but gives off a red-orange glow when it’s put in a vacuum tube and electricity is passed through it for a neon sign.
• Plastic is an organic compound, but it’s usually considered an inorganic material because it takes so long—centuries—to decompose.

tryptophan synthetase
