Converse (1908)

Converse was founded in 1908 by Marquis Mills Converse in Maiden, Massachusetts. The company originally made rubber footwear, including galoshes and winter boots , before expanding into athletic shoes. Its famous Converse All-Star basketball shoe debuted in 1917 and would later become one of the most recognizable sneakers in history.

The brand’s biggest boost came from basketball star Chuck Taylor, who joined the company as a salesman and ambassador. His signature was added to the shoe in 1932, creating the legendary Chuck Taylor All-Star. More than a century after its founding, Converse remains a global fashion staple.

Whirlpool (1911)

Whirlpool traces its roots to 1911, when Louis Upton and his uncle Emory Upton founded the Upton Machine Company in Benton Harbor, Michigan. Their goal was simple but ambitious: add electric motors to washing machines and make household chores easier .

The company eventually evolved into Whirlpool Corporation and became one of the world’s largest appliance manufacturers. Over the decades, it introduced innovations ranging from automatic washing machines to appliances used in NASA’s Gemini and Apollo-era space programs.

3

Colgate (1806)

Colgate’s story began in 1806 when English immigrant William Colgate started a starch, soap, and candle business in New York City . At the time, toothpaste in tubes did not even exist.

During the nineteenth century, the company expanded into oral-care products and eventually became one of the most recognized names in dental hygiene. Today, many consumers think of Colgate as a modern toothpaste brand, but its origins go back more than two centuries.

4

L.L. Bean (1912)

In 1912, Leon Leonwood Bean launched a mail-order business from Freeport, Maine. His first product was a hunting boot designed to keep outdoorsmen comfortable in wet conditions .

The original boot became known as the Maine Hunting Shoe and helped build a company famous for quality outdoor gear. L.L.Bean remains headquartered in Maine and continues to attract customers seeking durable products inspired by the outdoors.

5

3M (1902)

Today, 3M is known for everything from Post-It Notes to industrial products, but it started in 1902 as the Minnesota Mining and Manufacturing Company in Two Harbors, Minnesota . Ironically, its original mining venture failed.

Rather than disappear, the company reinvented itself by producing abrasives and sandpaper. That willingness to innovate eventually led to thousands of products and more than a century of inventions used in homes, offices, hospitals, and factories all around the world.

6

Red Wing Shoes (1905)

Red Wing Shoes was founded in 1905 in the Mississippi River town of Red Wing, Minnesota. The company specialized in rugged footwear for workers in demanding industries such as farming, mining, and construction .

Its reputation for durability has helped it survive dramatic changes in the American industry. More than a century later, Red Wing Boots remain popular among both workers and fashion enthusiasts who appreciate classic American craftsmanship.

7

Fruit of the Loom (1851)

Fruit of the Loom traces its history to 1851, making it one of the oldest brands on this list. The company began as a textile manufacturer in Rhode Island during an era when the country was still expanding westward.

Its colorful fruit logo became one of the most recognizable trademarks in America. Although consumers usually associate the brand with T-shirts and underwear, its roots stretch back to the earliest days of America’s industrial manufacturing.

8

Gibson (1894)

Founded in Kalamazoo, Michigan, in 1894 by Orville Gibson, this brand became one of the most influential guitar makers in music history. The company helped shape the sound of blues, jazz, country, and rock music .

Its instruments have been played by legendary musicians including B.B. King, Chuck Berry, Jimmy Page, and Slash, among many others. Despite being well over a century old, Gibson remains one of the most relevant and in-demand names in the guitar world.

9

Jell-O (1897)

Jell-O began in 1897 when carpenter and cough-syrup manufacturer Pearle Bixby Wait developed a flavored gelatin dessert . His wife, May, suggested the catchy name that would become famous nationwide.

The dessert gained popularity through aggressive advertising and recipe campaigns in the early twentieth century. For generations, Jell-O has been a familiar part of family gatherings, school cafeterias, and holiday meals.

10

New Balance (1906)

New Balance was founded in Boston in 1906 by William J. Riley. Interestingly, the company did not begin by making running shoes. Instead, it produced arch supports and orthopedic products designed to improve comfort and balance, hence the name .

The company later expanded into athletic footwear and became known for its emphasis on fit and performance. Today, New Balance competes with much younger sportswear giants while carrying more than a century of history behind it.

11

Stanley (1913)

Stanley was founded in 1913 when inventor William Stanley Jr. introduced an all-steel vacuum bottle . His innovation improved durability and helped popularize insulated drink containers.

For decades, Stanley products were associated with workers, campers, and outdoor enthusiasts. In recent years, the brand has experienced a surprising resurgence among younger consumers, proving that even a company founded before World War I can find new audiences.

What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

2

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

3

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4

A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5

Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6

Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

7

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8

No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9

Liberty for all (the coins)

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10

A global currency

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.

There's an unexplained billion-year gap

Look closely at the canyon walls, and you'll notice something strange: a clean, sharp line where ancient rock simply stops, and a much younger layer begins directly above it.

This geological puzzle is called the "Great Unconformity," and it represents over a billion years of rock layers that are simply absent , as though that stretch of time never happened. In some spots, rock dated 1.8 billion years old sits directly beneath rock that is only 520 million years old. Where did the missing billion years go?

The leading theory involves the violent breakup of an ancient supercontinent, but scientists are still piecing it together.

During the Cold War, it hid a nuclear fallout shelter

During the Cuban Missile Crisis in 1962, the U.S. government converted part of the Grand Canyon Caverns into a fallout shelter. This dry cave system, more than 200 feet underground, was stocked with enough food and water to sustain 2,000 people. Naturally, it was never occupied, and the supplies were never used.

The caverns have since been transformed into a tourist attraction, with organized tours winding through the same underground chambers that were once intended as a refuge from nuclear war. You can even book a night's stay there.

The Federal Aviation Administration was founded after a crash over the canyon

In 1956, two commercial passenger planes collided in midair over the eastern Grand Canyon, killing all 128 people on board both crafts. Rescue teams struggled to reach the wreckage deep inside the canyon, and the extreme heat of the crash had caused the planes' aluminum to fuse with the bedrock. There were no survivors.

The disaster exposed a terrifying truth: the U.S. air traffic control system was dangerously outdated, relying on pilots' visual estimates and rough guesswork from controllers , with no way to separate fast-moving aircraft from slow ones, or instrument-flying planes from those navigating by sight. Congress responded by passing legislation that created both the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

4

A hoax suggested that an Egyptian civilization had lived there

In 1909, the Arizona Gazette reported that an explorer named G. E. Kinkaid had discovered a vast underground citadel inside the canyon, filled with artifacts linked to ancient Egyptian civilization. He even claimed the expedition had been funded by the Smithsonian.

This story described hieroglyphics on the walls, mummies in the chambers, and relics pointing to a direct connection with the Egypt of the pharaohs. It was incredibly detailed, and it was, of course, a hoax. No evidence for any of Kinkaid's claims ever surfaced.

5

Fewer than 100 people have ever hiked its full length

Among the few people who have completed the through-hike of the Grand Canyon is Jen Hogan, the first woman to accomplish it, finishing her journey in 2021–2022.

It’s a full 800-mile length below the rim. The route involves extreme heat, flash floods, near-impassable areas, and stretches with no water or trail whatsoever. Around 60 or 70 people have reportedly accomplished it. This makes it one of the most exclusive feats on Earth.

6

The Grand Canyon's rocks predate dinosaurs entirely

Visitors scanning the canyon walls for fossils are often surprised to learn they won't find any dinosaur bones here. The rock layers of the Grand Canyon are simply older than dinosaurs. This fact alone can be shocking: staring at its walls means staring at marine fossils from as far back as 1.2 billion years ago. Some of its caves hold the remains of ancient mammals. The canyon is a window into a world that existed long before the dinosaurs, when the land that is now Arizona lay beneath a shallow sea.

7

The park is bigger than Rhode Island

Numbers alone rarely capture the Grand Canyon's scale, so here's a different approach. Rhode Island covers about 1,214 square miles, and the Grand Canyon National Park spans 1,904 square miles.

The canyon's depth exceeds four Empire State Buildings (which is 1,454 feet) stacked on top of one another. That’s 6,093 feet at its deepest point.

8

But it's not the deepest canyon on Earth

For all its grandeur, the Grand Canyon does not hold the depth record. Pictured above, the Yarlung Tsangpo Grand Canyon in Tibet, China, plunges to 17,567 feet, which is nearly three times deeper. Carved by the Yarlung Tsangpo River as it cuts through the eastern Himalayas, that canyon is so remote and extreme that it remained largely uncharted until the late 20th century.

9

It is home to a pink rattlesnake found nowhere else on Earth

The Grand Canyon Pink Rattlesnake has a pinkish-red coloring that matches the canyon's own distinctive rock walls so closely that it's nearly invisible. It is found nowhere else in the world. Officially classified as Crotalus oreganus abyssus , it has darker diamond-shaped markings along its back that deepen the camouflage further.

10

There's a village at the bottom: Supai Village

For over 1,000 years, the remote village of Supai has been home to the Havasupai Tribe, the People of the Blue-Green Waters. It is located an eight-mile hike from the rim, but sits roughly 3,000 feet deep inside the Grand Canyon.

The U.S. Department of Agriculture has called it the most remote community in the contiguous United States, and it has no automobiles and no road access. The only ways in are on foot, by mule, or by helicopter. It is also the only place in the United States where the postal service still delivers mail by mule train.
