McDonald’s

We’ll start with probably the most popular fast-food brand in the world. Few logos are as intently recognizable as McDonald’s "golden arches", to the point that they are present in virtually every single country in the world. But before it became an international behemoth, this fast-food chain began as a single restaurant in San Bernardino, California, founded in 1940 by brothers Richard and Maurice McDonald.

We could probably fill this entire article with McDonald’s fun facts, like how an astronaut smuggled a cheeseburger onboard a space shuttle. However, we’ll end this entry with the fabled Big Mac index: Since, as we previously mentioned, McDonald’s restaurants are virtually everywhere, economists have used the price of a Big Mac burger as a global indicator of each country's economic strength.

Burger King

While Burger King is often and unfairly considered to be playing second-fiddle to McDonald’s, the truth is that this chain is definitively fast-food royalty. First founded as Insta-Burger King in 1953, this restaurant offers a selection of burgers, fries, and other delectable products.

Burger King is perhaps most well-known for its signature burger, the " Whopper ". Created in 1957, this iconic product was the very first of its kind, causing competing franchises to develop their very own signature burgers. The Whopper’s legacy resulted in Burger King proudly adopting the nickname "Home of the Whopper".

Taco Bell

You might be surprised to learn that Taco Bell , synonymous with one of Mexico’s most treasured culinary delicacies, was actually founded in America. Not only that: Did you know that the Bell in Taco Bell’s name comes from the founder’s last name?

When Glen Bell started his company in 1953, he didn’t know that this little taco stand would eventually grow into a massive chain serving over two billion satisfied customers each year. Taco Bell is known for a myriad of delicious meals, including its iconic "Crunchwrap Supreme".

Domino’s

In 1960, brothers Tom and James Monaghan bought a small pizza chain close to Eastern Michigan University called "DomiNick’s". Little did the brothers know that they would turn this $1400 investment into one of the biggest pizza chains in the world , with approximately 15,000 locations all around the world.

Known for its 30-minute guarantee, Domino’s offers delicious and affordable pizza delivered with pinpoint accuracy. Over 60 years have passed since its founding, but this pizza chain remains a beloved American icon.

Wendy’s

Who said that hamburgers need to be round? Wendy’s is a living testament that burgers will always be delicious, no matter what shape they are in. This iconic chain’s burgers are particularly famous for their two main characteristics: Their legendary square shape and the fact that their meat is always fresh and never frozen.

You might be curious as to who the titular Wendy featured in every restaurant is. Well, the restaurant’s founder Dave Thomas named it after his fourth daughter, Melinda Lou, who was known as "Wendy" from an early age. Not only that, Melinda’s likeness was used as the company’s logo, and she continues to serve as its official mascot.

KFC

Just like Dave Thomas modeling his company’s logo after his daughter, KFC chose to honor its founder by making him an instantly recognizable icon. After all, this iconic fast-food chain’s history starts with Colonel Harland Sanders’ will and determination to drive his family out of their humble beginnings.

In the 1930s, Sanders took the cooking skills he learned from his mother as a child and founded a small restaurant called "Sanders Court & Café". By the 1950s, he saw the potential that franchising provided and opened the very first "Kentucky Fried Chicken" in Salt Lake City. Nowadays, KFC operates thousands of locations all over the world, all of which serve the Coronel’s legendary chicken seasoned with his "11 herbs and spices".

Starbucks

We’ve been dealing with burgers and fried chicken for a while now, so how about a nice cup of Joe instead? While we were hesitant to add Starbucks to the realm of fast food, the truth is that this international company has grown into the world’s largest coffeehouse chain , all the while optimizing the process of delivering a hot and delicious cup of coffee to the hands of the consumer.

Founded in Seattle in 1971, Starbucks was named after a character from Herman Melville’s classic novel "Moby-Dick": In that sense, the twin-tailed mermaid that serves as their iconic logo was also inspired by Melville’s masterpiece. Starbucks is world-famous for its innovative drinks, including the revolutionary cold coffee brew known as the "Frappucino".

Subway

If you are looking for a healthy yet equally accessible fast-food restaurant, then Subway is the place for you. This company was first founded in 1965 by friends Fred DeLuca and Peter Buck, hoping to save enough money to pay for medical school tuition. By the start of the new millennium, Subway became one of the world’s most profitable franchises, as well as one of the fastest growing.

Known for their world-famous slogan "Eat Fresh", Subway’s main appeal is the fact that you can select which ingredients you want in your sandwich. While products like the "B.M.T." or the "Italian Hero" keep their distinctive identity, being able to add your favorite flavors onto your sandwich truly provides a tailor-made customer experience.

White Castle

While it might seem smaller compared to other international juggernauts in this list, White Castle holds the remarkable distinction of being the world’s very first fast-food hamburger chain . Just like many other restaurants, the humble beginnings of White Castle started in 1916 when a cook named Walt Anderson opened his first diner in a converted streetcar. Five years after that, Anderson partnered with Billy Ingram to found the very first White Castle restaurant in Wichita, Kansas.

Over a hundred years after this first location, White Castle is still a beloved destination for all burger lovers. Their most famous product is probably their iconic "sliders", complete with square patties and steamed onions.

Pizza Hut

We’ll end with another pizza institution. Founded in 1958 by two Wichita State students, Pizza Hut locations are instantly recognizable by their distinctive architecture, which features a red rooftop resembling a hut. Moreover, while their pizza is certainly delicious, Pizza Hut holds the distinction of owning one of the most groundbreaking achievements in pizza delivery history.

While Domino’s prides itself on its 30-minute delivery policy, Pizza Hut holds the record of the very first outer-space delivery in history. In 2001, the company designed a vacuum-sealed pizza suitable to be delivered to the International Space Station. This interplanetary pie literally reached the stars, where it was happily enjoyed by Russian cosmonaut Yuri Usachov.

Decoration Day

Memorial Day was originally called Decoration Day and was first observed on May 30, 1868, as a way to honor Union soldiers who had died in the Civil War. However, the idea behind it actually came from the South. Mary Ann Williams , whose husband died during the conflict, wrote a letter to a newspaper urging women to set aside a day to decorate the graves of fallen soldiers.

2

The end of May

Decoration Day was instituted by the Army’s commander-in-chief, General John A. Logan , and was quickly adopted by most states. There are several theories about why the date was chosen: some say Logan purposely picked a day that was not the anniversary of any Civil War battle, while others believe he chose it because it’s the time of year when most flowers bloom.

3

National Cemeteries

During the American Civil War, the U.S. Congress passed an act to create military burial places for Union soldiers. By the end of that year, 12 national cemeteries had been established. Today, the National Cemetery System maintains 164 military burial sites, the most well-known being Arlington National Cemetery and Gettysburg National Cemetery .

4

Renaming

The term Memorial Day was first recorded in the 1880s and grew increasingly popular after World War II. However, the holiday wasn’t officially renamed until 1968, when the Uniform Monday Holiday Act moved its observance from May 30 to the last Monday in May.

5

A moment for remembrance

The establishment of Memorial Day weekend has been seen by some as a benefit to the travel, sports, and entertainment industries. Veterans’ organizations have urged that the holiday be returned to its original date, arguing that the three-day weekend undermines its intended meaning. In response, Congress passed the National Moment of Remembrance Act , which encourages people to pause at 3:00 p.m. for a moment of silent reflection and remembrance.

6

Poppies

Several English-speaking countries adopted the poppy flower as a symbol of remembrance for fallen soldiers after World War I. This tradition was inspired by the poem In Flanders Fields , written by Canadian military doctor John McCrae , which describes poppies growing among soldiers’ graves. In the United States, the poppy was originally associated with Veterans Day but is now primarily worn during Memorial Day weekend.

7

The flag

The national flag flies at half-staff during periods of mourning. While special instances of mourning can be proclaimed by government authorities, remembrance holidays follow a set protocol. On Memorial Day, the U.S. flag is briskly raised to the top of the staff, then solemnly lowered to half-staff, where it remains until noon. At that time, it is raised again to full staff to honor the nation’s living heroes and those still serving.

8

The Unknown Soldier

One of the focal points of Memorial Day is the Tomb of the Unknown Soldier at Arlington National Cemetery . This symbolic monument was established in 1921 and originally held the remains of an unidentified soldier who died in World War I. Later, unidentified soldiers from World War II and the Korean War were also interred at the site. A permanent military guard stands watch year-round, honoring the sacrifice of all unidentified service members.

9

Memorial Wreaths

Wreaths are a common sight on Memorial Day—but where does the tradition come from? In 1992, Morrill Worcester, owner of a wreath company in Maine, found himself with a surplus of holiday wreaths. Wanting to put them to good use, he donated them to Arlington National Cemetery as a tribute to the fallen—a gesture that soon became an annual tradition. After a photo of the wreath-covered graves went viral in 2005, the nonprofit organization Wreaths Across America was established to help volunteers place wreaths on veterans’ graves across the country.

10

The start of the summer

Even though it is a day of remembrance, Memorial Day weekend also marks the unofficial start of summer . The holiday often coincides with the end of the school year, and the warmer weather encourages families to gather for barbecues and cookouts, attend parades, and visit the graves and memorials of fallen soldiers.

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.
