What Are Loofahs Made Of?

Bath time, spa experiences, and even common household chores just wouldn't be the same without the humble sponge. Sponges, mostly from class Demospongiae, have been sold commercially as cleansing aids for thousands of years, and have also been used as water filters, padding for soldiers’ helmets, and for painting and decorating. (The brightly-colored pad hanging out by your kitchen sink right now is, of course, a synthetic design modeled after nature's handy tool.)

Although natural loofahs resemble their bathroom counterparts, they're actually about as unrelated as it’s possible to be. The loofah you scrub with is a dried-out tropical or subtropical gourd belonging to genus Luffa (most often either species L. aegyptiaca or L. acutangula). And while no one is completely sure where it originated—as W.M. Porterfield wrote in a 1955 Economic Botany article: "[c]ultivation of the sponge gourd is of such ancient origin that it is impossible to determine whether the original home was in Africa or Asia” [PDF]— a study in 1990 indicated that it was probably first cultivated in India. These plants—which look a bit like giant cucumbers—grow year-round in almost any tropical climate and places that have warm seasons, so long as there is plenty of moisture and no risk of frost.

Like sponges, the fibrous dried luffa has likely been used in Egypt and Asia for up to a couple thousand years. But its biggest boost as a cleansing tool began in the early 1890s, when Japan started cultivating commercial luffa crops for international export. (Prior to that, luffas were mostly used when a thorough household scrubbing was in order.) Word spread about the exfoliating item just as bathing suits and hemlines began retreating in the late 19th and early 20th centuries, according to The New York Times Magazine, which left many women with newfound anxiety about the smoothness of their skin. Inventions like the Improved Bathing Mitten, patented in 1889 by Judson S. Snyder of Brooklyn, New York, transformed the large gourds into easier-to-handle versions. By 1893, “no one seemed able to agree on how to spell the name of that sponge, but it inspired such a craze [that one] expected to see ‘a ‘loafer,’ ‘luphar,’ a ‘loopa’ or a ‘loofah’ in every wash basin the land,'” according to that same New York Times Magazine article.

But cleaning isn't all they're good for. According to Porterfield, commercial cultivation of the plant in the 1890s also let luffas fill a wide range of industrial roles. Before the second World War, over half of imported luffa goards were used in filters (chiefly in the Navy) for everything from steam to diesel engines. They also found use as water filters, industrial scourers, and even surgical tools. After wartime conflict drove Western powers to start sourcing their luffa shipments elsewhere, the dried veggies continued to prove useful through the mid-20th century as an effective sound-proofing material for tanks, helmets, and certain kinds of buildings.

When man-made materials began taking over many industrial roles in the 20th century, the noble luffa was mostly returned to its role as a cleaning tool—and, of course, a popular food, one that easily stands in for cucumbers or summer squash while it’s still immature. The vine is so easy to grow that it has been floated as a candidate for a profitable, sustainable crop to help drive economic and agricultural development here in the U.S. as well as countries like Paraguay [PDF]. Because they’re so resilient, luffa vines can be easily grown by amateur gardeners in much of the country (apart from the upper Midwest and New England), so feel free to take a whack at rearing this useful gourd—just make sure that any luffas that find a place in your bathroom don’t end up being a farm for bacteria themselves.

Atlanta Shelters Give Pups a Temporary Home for the Holidays

The holidays are looking a little brighter for adoptable dogs from two animal shelters in Atlanta, Georgia. As ABC News reports, a new program called Home for the Pawlidays is providing temporary homes to longer-term residents of Fulton County Animal Services and DeKalb County Animal Services for the week of Thanksgiving.

The initiative was organized by Atlanta's LifeLine Animal Project, a local group dedicated to providing healthcare and homes to shelter dogs. The dogs that were chosen for the project may be older, have special health needs, or other issues that make it more difficult to find them forever homes.

But from November 18 to 25, the dogs are getting to spend time away from the shelter and in the homes of loving foster families.

“We were thinking, everyone gets a break from work, and they should get a break from the shelter,” LifeLine’s public relations director Karen Hirsch told ABC News.

Some caretakers have already fallen in love with their four-legged house guests. Foster Heather Koth told ABC that she hadn’t been considering adoption, but after meeting Missy the shelter dog, she now plans to foster her until she has a permanent home or possibly adopt the dog herself.

And for the dogs that can’t be kept by their temporary owners, just a week of quality playtime and sleeping in a real bed can make a huge impact. You can check out photos of the pets who are benefiting from the program this week below.

25 Things You Didn't Know About Turkeys

Most of us probably associate turkey with a sumptuous Thanksgiving spread, but there’s a lot more to the big bird than how delicious it is alongside your grandma’s famous cranberry sauce. Here are a few bits of knowledge you can drop over the dinner table—when you’re not fighting with your family over white meat or dark meat, that is.

1. THE NORTH AMERICAN WILD TURKEY POPULATION WAS ALMOST WIPED OUT.

Wild turkeys once roamed the continent en masse, but by the early 20th century, the entire U.S. population had been whittled down to a mere 30,000 due to hunting and the destruction of their woodland habitats. In the 1940s, many of the remaining birds were relocated to parts of the U.S. with recovering woodlands so the turkeys could repopulate. Despite these efforts, by 1973, there were still just 1.5 million wild turkeys in North America. Today, that number is up to about 6 million.

2. TURKEY APPENDAGES ARE LIKE MOOD RINGS.

The dangly appendage that hangs from the turkey’s forehead to the beak is called a snood. The piece that hangs from the chin is the wattle. These fleshy flaps can change color according to the turkey’s physical and mental health—when a male turkey (called a tom, of course) is trying to attract a mate, the snood and wattle turn bright red. If the turkey is scared, the appendages take on a blue tint. And if the turkey is ailing, they become very pale.

3. TURKEYS CAN FLY.

Well, domestic turkeys that are bred to be your Thanksgiving centerpiece can’t. They’re too heavy. But wild turkeys can, reportedly at speeds up to 55 miles per hour. Though they don’t go very far—usually less than 100 yards—wild turkeys are among the five largest flying birds in the world. They’re in good company: Others on the list include the swan and the albatross.

4. THEY CAN ALSO SWIM.

Turkeys don’t swim often, it seems, but they can, by tucking their wings in, spreading their tails, and kicking. In 1831, John James Audubon wrote, “I have been told by a friend that a person residing in Philadelphia had a hearty laugh on hearing that I had described the Wild Turkey as swimming for some distance, when it had accidentally fallen into the water. But be assured, kind reader, almost every species of land-bird is capable of swimming on such occasions, and you may easily satisfy yourself as to the accuracy of my statement by throwing a Turkey, a Common Fowl, or any other bird into the water.”

5. TURKEY POOP CAN TELL YOU A LOT.

The next time you happen across turkey poop—which happens all the time, we know—take a closer look at it. If the droppings are shaped like a “J,” they were left there by a male turkey. Spiral-shaped poo? The culprit is female.

The citizens of Pilot Rock, Oregon, probably don’t much care about the shape of the stuff, but more about the quantity of it. Earlier this year, Pilot Rock turned to the Oregon Department of Fish and Wildlife (ODFW) for help combating a flock of 50 to 70 wild turkeys that would periodically invade the town, destroy gardens, perch in trees, and poop on pickup trucks. The ODFW offered several solutions, but as far as we know the turkeys still rule the roost at Pilot Rock.

6. TURKEY PROBABLY WASN'T ON THE PILGRIMS' MENU.

Thanks to historical records, we know for sure that the Wampanoag brought deer, and the English brought fowl—likely ducks and geese.

7. BEN FRANKLIN DIDN'T REALLY WANT THE TURKEY TO BE OUR NATIONAL BIRD.

You may have heard that at least one of our Founding Fathers lobbied hard to make the turkey our national symbol instead of the noble bald eagle. That’s not quite true, but in a letter to his daughter, he did expound on the character of each, which may be where the rumor got started:

“For my own part I wish the Bald Eagle had not been chosen the Representative of our Country. He is a Bird of bad moral Character. He does not get his Living honestly. You may have seen him perched on some dead Tree near the River, where, too lazy to fish for himself, he watches the Labour of the Fishing Hawk; and when that diligent Bird has at length taken a Fish, and is bearing it to his Nest for the Support of his Mate and young Ones, the Bald Eagle pursues him and takes it from him.

“With all this injustice, he is never in good case but like those among men who live by sharping & robbing he is generally poor and often very lousy. Besides he is a rank coward: The little King Bird not bigger than a Sparrow attacks him boldly and drives him out of the district. He is therefore by no means a proper emblem for the brave and honest Cincinnati of America who have driven all the King birds from our country…

“I am on this account not displeased that the Figure is not known as a Bald Eagle, but looks more like a Turkey. For the Truth the Turkey is in Comparison a much more respectable Bird, and withal a true original Native of America… He is besides, though a little vain & silly, a Bird of Courage, and would not hesitate to attack a Grenadier of the British Guards who should presume to invade his Farm Yard with a red Coat on.”

8. ANOTHER TURKEY FAN: ALEXANDER HAMILTON.

Yep, A. Ham liked turkey. In fact, he thought eating turkey was practically a god-given right, and once remarked that "No citizen of the U.S. shall refrain from turkey on Thanksgiving Day."

9. TEDDY ROOSEVELT BELIEVED THE BIRDS WERE CUNNING PREY.

Ol’ TR may have been accustomed to hunting big game, but wild turkeys held a special place in his heart. He believed they were every bit as challenging to hunt as deer. In his 1893 book Hunting Trips of a Ranchman and the Wilderness Hunter, he wrote, “The wild turkey really deserves a place beside the deer; to kill a wary old gobbler with the small-bore rifle, by fair still-hunting, is a triumph for the best sportsman.”

10. WILD TURKEYS HAVE BETTER VISION THAN YOU DO.

Their fantastic vision is probably one reason Teddy Roosevelt found turkeys such a challenge to hunt. They can detect motion from many yards away, have vision three times greater than 20/20, and have peripheral vision of about 270 degrees. Ours, comparatively, is only 180. And although turkeys can’t see in 3D, they can see UVA light, which helps them better identify predators, prey, mates, and food.

11. THE TOP TURKEY-PRODUCING STATE MAY SURPRISE YOU.

You may know Minnesota for producing Prince, the Mall of America, and Target. But we also have the Land of 10,000 Lakes to thank for our Thanksgiving turkeys. According to the Minnesota Turkey Growers Association, approximately 46-48 million turkeys are produced in Minnesota every year. In fact, it’s where the turkey that receives a presidential pardon hails from every year. Speaking of which ...

12. THE PRESIDENTIAL TURKEY PARDON MAY DATE BACK TO ABE LINCOLN.

Officially, the tradition of the sitting president of the United States pardoning his Thanksgiving turkey dates back to John F. Kennedy, who decided to let his gift from the National Turkey Federation off the hook. But he wasn't the first president to let a turkey go free: When Abraham Lincoln’s son Tad befriended one of the birds intended for Christmas dinner in 1863, kind-hearted Abe granted it a stay of execution.

13. THE FIRST TV DINNER MEAL: THANKSGIVING LEFTOVERS

In 1953, Swanson ended up with 10 train cars full of frozen turkeys—260 tons of them—when an overzealous buyer ordered too many turkeys for the holidays. Salesman Gerry Thomas solved the problem by ordering 5,000 aluminum trays and setting up an assembly line of workers to scoop dressing, peas, and sweet potatoes into the compartments. Slices of turkey rounded out the meal, which Swanson sold for 98 cents. The idea was a hit: The following year, 10 million turkey TV dinners were sold.

14. NATIONAL TURKEY LOVERS’ MONTH ISN’T WHEN YOU THINK.

Everyone eats turkey in November and December, so there’s not a lot of need for extra poultry promotion during those months. If you want to celebrate National Turkey Lovers’ Month, you’ll have to do it in June with some turkey brats and burgers on the grill.

15. THE TURKEY YOU’LL BE EATING IS PROBABLY ABOUT 18 WEEKS OLD.

That’s how long it typically takes the birds to grow to maturity, which is when they’re usually slaughtered.

16. THERE WAS ALMOST A TURKEY SIDEKICK IN POCAHONTAS.

At one point, Disney thought Pocahontas needed a little comic relief, so they hired John Candy to voice a wisecracking woodland fowl named Red Feather. Sadly, Candy passed away while the logistics were being worked out, so animators dropped the turkey entirely and opted for a clever raccoon named Meeko.

17. NOT ALL TURKEYS GOBBLE.

If you hear a turkey making the distinctive noise we all associate with them, then you’re hearing a male communicating with his lady friends up to a mile away. Females make a clicking sound instead of a gobble.

18. IF YOU DON’T EAT TURKEY AT THANKSGIVING, YOU’RE IN THE MINORITY.

According to the National Turkey Federation, 88 percent of Americans eat turkey at Thanksgiving.

19. TURKEY CRAVINGS CAUSED A SPIKE IN KFC SALES IN JAPAN.

When KFC opened its first stores in Japan in the 1970s, the company was surprised to find that sales soared during the holidays. The phenomenon stymied executives since most of Japan celebrates neither Thanksgiving nor Christmas. It was later discovered that foreigners craving holiday turkey had decided that KFC’s chicken was the next best thing. After the company figured this out, they played up the association with their “Kurisumasu ni wa kentakkii!” campaign—“Kentucky for Christmas.” It worked on tourists and locals alike, and today, Christmas Eve is still the highest-selling day for KFC Japan.

20. THERE IS PROPER TURKEY TERMINOLOGY.

You probably know that a group of turkeys is a flock, but they can also properly be called a “rafter.” And should you want to call baby turkeys something a little more precise, you can call them “poults.”

21. THE MAYA USED TURKEYS AS SACRIFICIAL OFFERINGS.

Archaeologists have found vases dating from 250-800 CE that have turkeys depicted on them. According to University of Wisconsin-Milwaukee art historian Andrea Stone, "turkeys were quintessential animals for feasting and for sacrificial offerings." The Maya even crafted tamales shaped like the birds.

22. DURING THE ‘70S, YOU COULD CALL JULIA CHILD FOR TURKEY ADVICE ON THANKSGIVING.

Even when she was at peak popularity, the famous chef refused to remove her phone number from public listings. According to friends, complete strangers would call Child on Thanksgiving to ask for advice on cooking the perfect turkey. Julia always answered the phone, and typically told callers whatever they needed to hear to get them to relax and enjoy the holiday. She even told some amateur cooks that turkey was best served cold anyway.

23. BIG BIRD IS A TURKEY.

Well, according to Sesame Street, he’s actually a canary—but his plumage makes him a turkey. The good people at American Plume & Fancy Feather provide Sesame Street with several thousand turkey feathers per costume to make sure Big Bird looks soft and fluffy.

24. THE BIRD IS NAMED AFTER THE COUNTRY.

But the whole thing was a mistake. Centuries ago, the English began to import a rather tasty bird, now known as a helmeted guinea fowl, from Madagascar. But they didn’t know it was from Africa. Because it was imported to Europe from merchants in Turkey, the English believed the birds were also Turkish.

Later, when the Spanish arrived in the New World, they discovered Meleagris gallopavo—the wild turkey. It was delicious, so they started importing it back to Europe. Europeans thought it tasted like the “turkey” guinea fowl they had been enjoying, so they called it the same thing.

25. WHAT, EXACTLY, IS DARK MEAT?

It’s just a different type of muscle than white meat. White meat is the result of glycogen, which doesn't need much oxygen from the blood because the muscles it fuels only require short bursts of energy. Dark meat, however, is found on wings, thighs, and drumsticks—muscles that are used for long periods of time and require more sustainable energy. It’s made dark by the proteins that convert fat into energy.
