Ronald Reagan: The Jelly Bean Fanatic

Ronald Reagan kept a jar of jelly beans on his desk in the Oval Office and on Air Force One . Blueberry was his favorite flavor, and 3.5 tons of jelly beans were shipped to Washington for his 1981 inauguration.

The Jelly Belly company even created a special blueberry flavor just for Reagan's presidential inauguration. Cabinet meetings apparently featured bowls of the colorful candies, and Reagan would munch on them during crucial policy discussions.

John Quincy Adams: The Naked Swimmer

John Quincy Adams had a rather unusual morning routine that would absolutely not fly today. The sixth president would wake up early, walk down to the Potomac River, strip off all his clothes, and go for a refreshing swim .

Legend has it that a female reporter once caught wind of this habit and sat on his clothes until he agreed to give her an interview. Adams apparently took it in stride, though one imagines the Secret Service would have a collective heart attack if any modern president tried this stunt.

Teddy Roosevelt: The One-Man Zoo

Theodore Roosevelt ran a wildlife sanctuary at the White House . His kids had a veritable menagerie that included a badger, guinea pigs, snakes, and even a one-legged rooster. There are also claims that he kept a bear and a hyena in the House. Oh, and let's not forget about the pony that his son Quentin once took up in the White House elevator.

When President Roosevelt's son Archie fell ill and was confined to bed, his brothers Kermit and Quentin decided to cheer him up by bringing their pony, Algonquin, up to his room via the White House elevator. The plan nearly backfired, though: Algonquin became so captivated by his own reflection in the elevator mirror that getting him out proved to be quite the ordeal.

Thomas Jefferson: Ice Cream Pioneer

After his time in France, Jefferson returned with a fancy ice cream recipe and became one of the first Americans to popularize it . He reportedly had an 18-step process for making the stuff.

The Founding Father loved ice cream so much that he designed a special ice house at Monticello, though its purpose went beyond just frozen treats. The structure stored ice and snow harvested from the Rivanna River to refrigerate fresh dairy and meats throughout the year, with ice cream being just one of the delicacies it made possible.

Andrew Jackson: Profanity Parrot Owner

Andrew Jackson's pet parrot, Poll, learned a colorful vocabulary from Old Hickory himself. When Jackson died in 1845, the parrot attended his funeral. Unfortunately, as some witnesses declared, Poll had to be removed from the service because the bird wouldn't stop cursing loudly at the mourners.

You have to wonder what that scene was like—somber grieving interrupted by a parrot dropping f-bombs left and right. It's both mortifying and hilarious to imagine the reverend trying to continue the eulogy while this feathered menace squawks profanities from the corner.

Gerald Ford: The Model President

Before Gerald Ford became president, he was a legitimate male model . In the 1940s, the future president appeared on the cover of Cosmopolitan magazine.

Ford had been a star football player at the University of Michigan, and his athletic build and fame caught the attention of photographers. He modeled to make extra money, appearing in fashion spreads and looking quite dashing, we might add.

LBJ: The Presidential Prankster

Lyndon B. Johnson owned an amphibious car that could drive on both land and water. His favorite party trick was to drive guests around his Texas ranch and then pretend the brakes had failed as they headed straight toward a lake . People would scream in terror as the car splashed into the water.

Then, to everyone's shock and relief, the car would simply start floating. Johnson would burst into laughter while his passengers tried to recover from their near-death experience.

8

William Howard Taft: Bathtub Troubles

William Howard Taft was America's heaviest president, weighing in at around 340 pounds. The most famous anecdote about him involves getting stuck in the White House bathtub , though historians debate whether this actually happened. What's definitely true is that he had a custom bathtub installed that could fit four normal-sized men.

9

Calvin Coolidge: The Prankster President

There are claims that Calvin Coolidge would sometimes press all the buttons on his desk to summon his staff, then hide to watch them run around confused, looking for him . Very mature, Mr. President.

Coolidge also had a pet raccoon named Rebecca, who walked on a leash around the White House grounds. Silent Cal might not have talked much, but his actions —and his choice in pets— spoke volumes about his quirky sense of humor.

10

Jimmy Carter: UFO Witness

Jimmy Carter once filed an official report claiming he saw a UFO . In 1969, before becoming president, Carter and a group of people in Georgia witnessed a strange, bright light in the sky that changed colors and moved in unusual ways. He was so convinced of what he saw that he filed paperwork with the International UFO Bureau.

Carter promised during his campaign that if elected, he would release all government information about UFOs. Once in office, though, he was reportedly told some things were too classified even for the president.

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.

2

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.
