Unlimited drink refills

The only thing better than a tall glass of iced tea on a hot day is knowing that you can get up and get a refill as many times as you want. This is nothing new for Americans, but it’s one of the most surprising things for foreign tourists. While American restaurants see unlimited refills as a way to keep customers happy at extremely low prices, in most other countries, you usually pay for each drink separately.

The measuring system

America follows the U.S. customary units system, which includes elements derived from the old Imperial System used in the United Kingdom. Why is it so difficult for foreigners from other English-speaking countries to understand the American system, then? Although countries like Canada or the UK use Imperial units for things like body weight or distances, they also use metric units for other areas, while non-English-speaking countries, as well as Australia and New Zealand, rely entirely on the metric system.

Sales taxes

How do you know if you have enough money to buy anything at a store? You look at the price and calculate the sales tax that will be added at checkout —unless you are in one of the five states that don’t charge sales taxes. If you travel abroad, however, you don’t have to worry about calculations; you just have to look at the price tag. It’s not that sales taxes don’t exist elsewhere, but that they are already included in the advertised tag.

Measuring temperature

If foreigners are confused about the American measuring system, they are definitely baffled by the way we measure temperature. The Fahrenheit scale was developed following scientific parameters, but also considering human body temperature: 0°F is really cold weather, and 100°F is really hot weather. The Celsius scale, however, is based on water: at 0°C, water freezes, and at 100°C, water boils. The range difference often results in foreigners being confused at the high temperature numbers.

5

Entrees

The topic of American portion sizes being bigger than portion sizes elsewhere is nothing new, but is not the only important difference when it comes to eating out. In a standard American menu, the Entree section will include dishes that are considered main courses, while the Appetizer section will have snacks or finger foods typically eaten before the main course. Why is this confusing for non-Americans? The word ‘entree’ originally referred to appetizers, and is still used with that sense in most countries, especially in Europe and Latin America.

6

Dollar bills

American dollar bills are easily recognizable all around the world, not only because they are often used as an international currency, but also because dollar bills are somewhat unique. Firstly, they are made of a special cotton and linen blend that gives them a unique texture and makes them extremely durable. They are also the same size and color, no matter the value, while other countries tie the size or color of the bill to the different values.

7

Decimals and thousands separators

This is less of a U.S. and more of an English-speaking countries issue, but one that confuses foreigners nonetheless. All around the world, we learn that big numbers are grouped in threes: once we go from nine hundred and ninety-nine to a thousand, we have to use a comma. Or is it a period? While English speakers use a comma for the thousands, non-English speakers use a period. When it comes to decimals, the symbols are also swapped: in English, decimals are separated by a period, but for the rest of the world they are separated by a comma.

8

Citizen-based taxation

Foreigners often find the American taxing system confusing, but this particular instance can also surprise many American citizens who realize that they have to pay taxes even if they live abroad and don’t do business or have properties in America. The U.S is one of two countries in the world that uses citizenship (and not residence) as a taxing basis. The only other country that uses this system is Eritrea, located in East Africa.

9

Political colors

The history of political colors in the U.S. is fairly recent —the red-blue dichotomy was formally established during the 2000 presidential election— but no less important or symbolic. It does, however, stand out from the political use of color in other parts of the world where —leaving specific color associations aside— red is often tied to left-wing ideologies, and yellow (not blue) is the color associated with liberalism.

10

Football

Why is America the only country that uses the name football for a sport that is not soccer? The English are to blame here. In the 19th century, football was used for many different sports, among them Rugby football, Association football, and Gridiron football. Association football, also called assoccer (and later, soccer), became extremely popular in England, while Gridiron became popular in America. While the English ultimately decided to use football for Association football, Americans had already identified that word with Gridiron football, so they adopted soccer as the alternative.

Gateway Arch’s time capsule

The Gateway Arch, the 630-foot-tall monument located on the west bank of the Mississippi River in St. Louis, Missouri, is famous for being the world's tallest arch. But few people know about the secret hidden at its peak.

In 1965, before the final piece of the stainless steel arch was put in place, a time capsule containing the signatures of 762,000 St. Louis students and residents was welded into the keystone. Just one more fun fact added to the mystique of this midwestern icon!

Have you ever wondered where Hollywood's golden age films are preserved? Well, as it happens, they are not in the basement of some Tinseltown studio but more than 650 feet below the surface in a facility in Hutchinson, Kansas. Established in 1959, Underground Vaults & Storage specializes in storing a wide range of valuables, including paper documents and client records.

In addition, this site is a precious resource for the entertainment industry. Underground Vaults & Storage preserves—under optimal temperature and humidity conditions—film copies of classic cartoons, television programs like Friends , game shows, soap operas, and even the original reels of cinematic masterpieces like The Wizard of Oz and Gone with the Wind .

A ‘Big Basket’ building

Image: Photo shot by Derek Jensen (Tysto, Public domain, via Wikimedia Commons

Who says a building has to look traditional to be iconic? Why settle for an ordinary office building when you can work inside a basket? That's what the executives of the Longaberger Company, an American manufacturer and distributor of handcrafted maple wood baskets, thought when they relocated to Newark, Ohio, in 1997.

Their headquarters was designed as a seven-story building, a perfect replica of the company's top-selling product, the Medium Market Basket. The massive handles are attached to the structure with copper and wooden rivets, and the gold-leaf-plated tags each weigh 725 pounds. Though the building was a novelty, the company eventually abandoned it, and it is now listed for sale.

Popping the question on top of the Empire State Building has become a cherished tradition in the United States. Thousands of couples travel from all over the country to get engaged at one of New York City's most iconic buildings. But did you know that you can also celebrate a wedding there?

Every February 14, a few lucky couples are granted the unique opportunity to exchange wedding vows at the building's 86th Floor Observatory. Since 1994, hundreds of couples have said "I do" at this breathtaking location, celebrating Valentine's Day at America's most romantic landmark.

A supernatural castle

Creativity, ingenuity, and perseverance can achieve extraordinary feats. Such is the case with Coral Castle, a massive limestone structure built by self-taught engineer Edward Leedskalnin in the early 20th century.

Located just north of Homestead, Florida, sits this construction built with stones larger than those at Stonehenge. Leedskalnin, who invested more than 28 years in this project, claimed that he raised it single-handedly using reverse magnetism and supernatural abilities. The truth is he probably used pulleys and other tools, but that doesn’t make it any less of a unique and original building that is a fascinating tourist attraction to this day.

Walt Disney's utopian city

Image: Paul Moody

Walt Disney was a visionary, and thanks to his infinite imagination today we have the most endearing characters and the best amusement parks in the world. But did you know that Disney originally envisioned his famous EPCOT Center as the blueprint for a larger utopian society?

EPCOT stands for Experimental Prototype Community of Tomorrow. Had Disney’s dream come to fruition, 20,000 people could have lived in a real, futuristic city complete with residential areas, shopping malls, factories, recreational parks, and a state-of-the-art multimodal road system to connect it all. Unfortunately, after his death in 1966, the company felt his original vision was a bit impractical. Instead, they created a theme park that captures the spirit of its creator, a permanent celebration of human achievement, from culture to technological innovation.

Secret codes

The CIA is a mysterious organization, so it's no wonder that there is a sculpture hiding secrets sitting right in the courtyard of the George Bush Center for Intelligence in Langley, Virginia.

Named "Kryptos," this large copper sculpture was installed in 1990 and holds a series of four encrypted messages. Only three of these codes have been cracked, while the fourth remains one of the most famous unsolved cryptograms in the world.

The paper house

It seems that the 1920s was a time of inventiveness, innovation, and originality in architecture. During this decade, the United States built the most impressive skyscrapers and, as we've explored, even a massive limestone castle. But a house made of paper? It seems almost impossible, doesn’t it?

Well, we are about to prove you wrong. In 1924, a mechanical engineer called Elis Fritiof Stenman built a summer cottage made almost entirely out of pasted, coated, or rolled-up newspapers. The only exceptions were the framework, floorboards, and shingles. The house is located in Rockport, Massachusetts, and, believe it or not, is still standing and can be visited.

Race into the sky

The Chrysler Building on the East Side of Manhattan in New York City was once the world’s tallest building, holding the title for 11 months. But did you know that it almost didn't make it? Industrial pioneer Walter Chrysler, who commissioned the project, wanted his building to be taller than the Eiffel Tower. Originally designed to be 925 feet tall , the imminent construction of other taller skyscrapers forced architect William Van Alen to revise his plans.

This competition for the title of the world’s tallest building became known as the " Race into the Sky ." To beat his opponents, Van Alen ordered a 125-foot spire to be built in secret. It would only be attached to the roof after the rival buildings were finalized. When it was finished in May 1930, the Chrysler Building reached 1,046 feet, making it the tallest man-made structure in the world at the time. Unfortunately, less than a year later, the Empire State Building would claim that honor.

A bridge that tells time? We are not kidding! When it’s not being used by pedestrians and cyclists to cross the Sacramento River in Redding, California, the Sundial Bridge at Turtle Bay serves as a giant timepiece.

The bridge's 217-foot support tower points north, and its shadow can be used to calculate the time. Designed by renowned Spanish architect Santiago Calatrava, it was completed in 2004. So now you know, if your watch breaks or your cell phone dies on your way to Turtle Bay Exploration Park, you don't have to worry, the Sundial Bridge will always tell you the time of day!

The Capitol Subway System

Few people know that a network of subway cars runs beneath Washington’s labyrinthine Congressional headquarters. The first Capitol Subway System opened on March 7, 1909, and has been transporting politicians seeking shelter from the weather—and curious onlookers—for more than a century.

The rails stretch for nearly a mile, connecting the United States Capitol to several congressional office buildings. While the public can ride the trains, the subway is restricted to congressional members and staff during votes.

Point Pleasant had quite a moment in the 1960s, when locals reported seeing a tall figure with glowing eyes sweeping through the sky. Newspapers named it the Mothman, and soon the stories were everywhere. Some people thought it was a bird, others guessed something stranger. The sightings even lined up with a real bridge collapse, which only added to the town’s long-lasting fascination.

Northern tribes have long shared stories about the Wendigo, a creature tied to greed, hunger, and the frozen wilderness. Descriptions vary, but all versions paint a picture of something you wouldn’t want to cross paths with on a snowy night. Whether seen as a physical creature or a spirit, the tale has survived because it taps into those deep winter fears we all understand, right?

The Pine Barrens have been home to strange stories since colonial days. One of the oldest is about Mother Leeds, who supposedly cursed her thirteenth child. Folks say the baby flew off into the forest and took on a life of its own, complete with wings and hooves. Sightings pop up every so often, especially during the wave of excitement in 1909, when everyone was looking over their shoulder.

Out in Beaver Dunes Park, people have been whispering for centuries about strange lights flickering across the sand. Early explorers were warned to steer clear, and some stories claim travelers simply vanished after a flash of eerie green. Modern visitors usually come for ATV rides, but the legend of an otherworldly doorway tucked into the dunes still gives the place a curious chill.

Escalante Petrified Forest is a beautiful destination, but visitors hear one warning loud and clear: leave the wood where it lies. Rangers say they get packages every year with pieces of petrified wood sent back by people who swear they had nothing but bad luck after taking a souvenir. Whether you believe in curses or just want a peaceful trip, it’s safer to enjoy the scenery with your hands empty.

The Cropsey tale in New York

Image: Mahdi Bafande

Growing up in New York, plenty of kids heard a version of Cropsey. Sometimes he was a runaway patient, other times a shadowy presence lurking near camps or tunnels. The unsettling part is that a real criminal case in the 1980s made the stories feel even closer to home. Over time, the legend inspired scary movies, bedtime warnings, and a whole generation of whispered fears.

Virginia’s Bunnyman

Clifton has a little train bridge that looks simple enough in the daytime. But the Halloween story tied to it turned it into a local fixture. Some say a dangerous fugitive patient once hid there. Others remember a real-life incident from the 1970s involving a hatchet and a mysterious figure. The tale grew in the retelling, and before long, the Bunnyman hopped right into regional folklore.
