Super Bowl - The biggest party in America

Where were you when you first watched the Super Bowl? Do you have an all-time favorite game you’ll never forget? The Super Bowl is the biggest, most-watched single event in the United States . It has become an unofficial national holiday that unites millions of Americans through a shared love of football.

The Super Bowl halftime show brings people together for a massive cultural performance featuring iconic artists. The commercials are also highly anticipated, with some of the biggest-budget campaigns talked about as much as the game itself. The shared experience, alongside incredible moments like miracle comebacks, is often paired with classic game-day foods such as chicken wings, nachos, and pizza.

Independence Day - Red, white, and boom

Independence Day marks the birth of the United States as a free nation. On July 4, 1776, the Founding Fathers adopted the Declaration of Independence, cutting ties with Great Britain. This holiday unites the country through traditions, patriotic reflection, and celebration.

It brings friends and family together from coast to coast to enjoy parades with marching bands, classic cars, and community floats; spectacular fireworks lighting up the skies across the country ; and cookouts with barbecues, picnics, and backyard games. Red, white, and blue fill the scene, alongside the national anthem, "The Star-Spangled Banner," reinforcing a shared sense of pride.

Thanksgiving - The ultimate family feast

Do you love inviting everyone for Thanksgiving and preparing the ultimate feast? Or do you prefer visiting loved ones you haven’t seen in a while? Thanksgiving unites Americans through gratitude, food, and tradition.

It began in 1621, when early English settlers and Native Americans celebrated the autumn harvest. In 1863, during the Civil War, President Abraham Lincoln made it a national holiday to heal and unite a divided country. With traditions ranging from turkey and stuffing to the Macy’s Thanksgiving Day Parade, NFL games, and volunteering at shelters, the holiday centers on gratitude and togetherness .

Christmas - A season of giving

Is Christmas your ultimate holiday? Do you look forward to it all year long? Even for those who don’t celebrate it religiously, it’s an occasion that blends diverse cultural backgrounds into a shared spirit of peace and goodwill . Traditions include the lighting of the National Christmas Tree in Washington, D.C., and large public celebrations in cities like New York.

President Ulysses S. Grant made Christmas a federal holiday in 1870 to help heal a divided nation after the Civil War. Today, that spirit lives on through neighborhoods turned into winter wonderlands with dazzling light displays, and comforting foods from turkey to apple pie, along with carols, gift-giving, and acts of charity.

New Year’s Eve Times Square Ball Drop - The countdown everyone shares

How important are your New Year's resolutions? Or are you just there for the midnight kiss? Either way, the New Year’s Eve Times Square Ball Drop is an iconic moment of unity.

Every December 31 at 11:59 p.m., the nation pauses to watch the countdown welcoming a fresh start. This tradition draws nearly one million people to New York City each year and reaches over one billion people worldwide through television and live broadcasts.

March Madness - Brackets, buzzer-beaters & cinderella stories

How much do you enjoy competition and surprises? That’s exactly what March Madness is all about: the annual NCAA college basketball tournament known for its chaotic and thrilling unpredictability.

From casual viewers picking teams based on the mascot that catches their eye to die-hard fans with a long family history supporting the teams, this three-week-long sporting event captivates Americans. Filling out "brackets" before the championship begins and watching underdog "Cinderella" teams rise through the one-and-done format are all part of the excitement, culminating in the iconic "One Shining Moment" montage.

Election Day - Democracy in action

Do you remember being little, knowing it was Election Day, and watching your parents head out to vote? Or the first time your children voted? Despite intense political differences, there are nationwide traditions that millions of American families share.

Standing in line side by side represents equal access to democracy . The "I Voted " stickers are badges of civic pride that often spark conversation. Similarly, the "I Voted selfie" has become a modern way to share the moment and encourage others to do the same. As the day comes to a close, "watch parties" bring people together, while concession and victory speeches symbolize the peaceful transition of power after the race is called.

8

Presidential Inauguration - A peaceful transfer of power

Presidential inaugurations are a symbol of American democracy, emphasizing the peaceful transition of power, respect for the Constitution, and hope for the future.

The first inauguration took place on April 30, 1789, when George Washington took the oath of office, reportedly adding the now-famous words "So help me God" . The first outdoor speech was given by Thomas Jefferson in 1801, reinforcing the idea of a government for the people. A more recent tradition is that the outgoing president leaves a letter for the incoming president, a gesture that shows the country is bigger than any political divide.

Memorial Day - Honoring the fallen

Memorial Day is a federal holiday observed in the United States on the last Monday of May. It’s a solemn day that honors the men and women who died while serving in the U.S. Armed Forces.

One of the most meaningful moments is at 3:00 p.m. local time, when people across the country pause for a moment of silence to remember the fallen . The day blends national remembrance with the unofficial start of the summer season through community events.

Veterans Day - A nation’s gratitude

Whether you are closely tied to the military or not, Veterans Day is deeply meaningful across the country. Observed annually on November 11, it honors all military veterans who have served in the United States Armed Forces . This holiday bridges political and cultural divides by prioritizing shared gratitude and respect for service.

The origin of the day goes back to Armistice Day, marking the end of World War I, as major hostilities ended at the 11th hour of the 11th day of the 11th month in 1918. Today, communities pause at exactly 11:00 a.m. for a moment of silence. Parades, from the New York City Veterans Day Parade to small neighborhood celebrations, as well as the wreath-laying ceremony at the "Tomb of the Unknown Soldier" at Arlington National Cemetery, remain powerful traditions.

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.
