Legal drinking age

Image: Elevate

When was the first time you tried a beer? Probably at 21 or later. While that's completely normal here in the US, it can seem a bit strange to people in other parts of the world. Why? In America, you can vote, serve on a jury, and even get married in some states at 18, but you still can't legally buy alcohol until you're 21. In many other countries, the legal drinking age is 18—or even younger—and that's why they find our law unusual.

The faces of real estate agents

We're used to walking through a neighborhood and seeing signs with real estate agents' faces in front of homes for sale. But in other countries, that's pretty unusual! In many places, real estate transactions are more impersonal; you deal with an agency, not a specific person. Here in the US, we like to put a face to the name. Getting to know the person helping you buy or sell a home feels more personal and trustworthy. It makes sense, right?

Our coins

Image: Shot by Cerqueira

Many of us don't even notice this until we travel abroad, but some of our coins don't actually show their value! Sure, you'll see words like "Five Cents," "One Cent," or even "One Dime," but there's no actual number printed on them. When you think about it, that's kind of strange, right? Especially when most countries display the value on their coins using numbers.

American flag everywhere

Image: camera obscura

In many countries, their national flag is used only for formal or official purposes, but that's not the case in the US. We tend to see the American flag literally everywhere, not just at official functions or holiday celebrations, but also on all kinds of products and imagery. From T-shirts and caps to food packaging and even swimsuits, our flag is a constant presence in everyday life.

No bad words on TV

If you're in America and turn on your TV right now, you'll find everything from romantic scenes to shows about zombies or violent crimes, but you'll rarely hear any bad language. Our television generally doesn't include insults or swear words, while in other countries they often do, even in shows that air during times when children might be watching.

Dinner before 8 PM

Image: Or Hakim

Depending on the region, dinner in the United States is often served before 8 p.m., and sometimes even before 7 p.m. But in many other countries, that's considered too early. In Latin America, for example, most people eat dinner between 8 and 11 p.m.!

The Imperial System

Image: Jarosław Kwoczała

We Americans use miles, feet, pounds, and degrees Fahrenheit, but this is often very confusing for visitors from other parts of the world. We are totally used to the Imperial System, but in most countries, the Metric System reigns supreme, with everything measured in meters, kilometers, kilograms, and degrees Celsius.

Big portions

Image: mafe estudio

Large portions are deeply ingrained in our daily lives. Whether it's restaurant meals, snack packs, or soft drinks, everything tends to be bigger in America. This can be surprising for foreigners who come here and order food, since in many other countries, dishes are smaller, and the custom of taking leftovers home after eating at a restaurant isn't as common as it is in the US.

Turkey pardon

The pardoning of the turkey by the US president is a big event for many Americans. But in other parts of the world, where Thanksgiving isn't celebrated, it can come as a surprise. To foreigners, this formal ceremony involving a turkey might seem quite strange. Since Thanksgiving traditions aren't part of their history, this custom is uniquely American.

Alumni homecoming

Perhaps you've had the chance to participate in Homecoming, the annual event that celebrates university spirit with parties, sports games, and other activities for students returning to campus. While it's a big part of our college tradition and communities are deeply involved, it's quite different in other parts of the world, where the return to school usually happens with little fanfare.

1

Mississippi River (New Orleans)

The Mississippi River, which flows through Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana, has long served as the backbone of commerce in America. Winding through 10 states, it connects farms, factories, and cities across the country .

New Orleans flourishes at its mouth, which turned it into one of America’s busiest ports. Goods from the Midwest, like grain, cotton, and timber, traveled downriver to ships bound for global markets.

2

Hudson River (New York City)

The Hudson River transformed New York City into the East Coast's leading port, as its deep waters allowed ocean-going ships from the Atlantic to travel far inland .

​

When the Erie Canal opened in 1825, it linked the Hudson River to the Great Lakes near Waterford, New York, about 150 miles north of the city. This created a direct trade route between the Midwest and the Atlantic, cementing New York’s economic dominance.

3

Chicago River (Chicago)

Chicago’s rise began with its strategic location along the Chicago River, a short but crucial waterway connecting Lake Michigan to inland routes .

With the construction of the Illinois and Michigan Canal in 1848, Chicago became the gateway between the Great Lakes and the Mississippi River basin, fueling explosive growth in trade and industry.

4

Charles River (Boston)

The Charles River played a central role in early American industry. In the early 1800s, mills along its banks harnessed the river’s power to run machinery .

The nearby textile mills in Waltham helped pioneer the American factory system. The Boston Manufacturing Company mill was the first fully integrated textile factory in the U.S., integrating the spinning, weaving, and finishing processes under one roof. The river’s energy helped transform the Boston region into a major industrial center.

5

Delaware River (Philadelphia)

Philadelphia was founded along the Delaware River, which quickly became one of colonial America’s most important trade corridors.

Ships carrying grain, lumber, and manufactured goods traveled between Philadelphia and the Atlantic . The river helped the city grow into one of the largest and most prosperous ports of early America.

6

Potomac River (Washington, D.C.)

The Potomac River helped determine the location of the nation’s capital, which was established in 1790. This broad waterway was intended to provide access between the Atlantic and the interior of the new country .

Early leaders, like George Washington, hoped the river would become a major commercial corridor linking the young capital to western towns through canals and improved navigation routes.

7

Schuylkill River (Philadelphia)

Flowing through Philadelphia, the Schuylkill River powered much of the city’s early industrial growth. Its waters supported mills and factories throughout the 19th century .

The Schuylkill Canal also carried vast shipments of Pennsylvania anthracite coal, providing the fuel that powered factories and heated homes across the growing nation.

8

Ohio River (Pittsburgh)

The Ohio River begins at Pittsburgh, where the Allegheny and Monongahela rivers meet. This strategic location turned the city into a gateway to the expanding American frontier .

Beginning in the 1810s, steamboats carried settlers and goods downstream to cities like Cincinnati and Louisville, helping Pittsburgh grow into a major industrial and transportation center.

9

Missouri River (Kansas City, Missouri)

The Missouri River served as a key launching point for westward expansion during the 19th century.

Kansas City grew where river trade intersected with overland trails heading west , including the Santa Fe and Oregon Trails. The river made the city a critical supply hub for pioneers and traders.

10

Detroit River (Detroit)

The Detroit River links Lake Erie and Lake St. Clair, forming a vital passage in the Great Lakes shipping system .

Detroit developed along this busy corridor, where ships transported iron ore, timber, and other raw materials. These resources helped fuel the city’s rise as a manufacturing center.

11

Cuyahoga River (Cleveland)

The Cuyahoga River winds through Cleveland before emptying into Lake Erie, creating a natural harbor that attracted industries .

Steel mills, shipyards, and refineries lined its banks during the late 19th and early 20th centuries, turning Cleveland into one of the Midwest’s most important industrial cities.

12

Colorado River (Las Vegas)

Though best known for carving the Grand Canyon, the Colorado River also helped make the rise of modern cities in the desert Southwest possible .

Projects like Hoover Dam and Lake Mead provided water supplies and hydroelectric power that supported the rapid growth of nearby cities, such as Las Vegas, in an otherwise arid region.

Bell-Bottom Pants

If you're attending a 1970s-themed costume party, what would you wear? Beyond your personal style, no '70s wardrobe could be complete without a good pair of bell-bottom pants.

These pants were everywhere back then. Available in all colors and styles, they were worn by young and old alike. While their stardom spanned from the late 1960s to the early 1980s, bell-bottoms actually emerged much earlier. When? In the 19th century!

The first to wear this style of pants were American sailors in the 1800s. But their purpose wasn't to look trendy. Sailors implemented them because the wide design made it easy to roll them up when it was time to get their feet in the water.

Polaroid Cameras

Your current cell phone camera is probably better than the analog cameras of the 20th century. But let's be honest—there's nothing quite like holding a physical photo you just took, right?

Okay, we admit it: nostalgia is kicking in. But still, who can deny that a picture is a beautiful memory that gives a sweet, homey touch to your house? Thanks to Polaroid cameras, those of us who grew up in the 1970s and 1980s know this all too well.

Although Polaroid cameras first emerged in the late 1940s , it wasn’t until 3 decades later that they reached their peak popularity, becoming an unmistakable symbol of the era.

Music videos

While music videos existed before the 1980s, that decade turned them into a global sensation.

One song marked a major turning point in the world of music videos. You probably already guessed it: we’re talking about Michael Jackson’s "Thriller." Released in 1983, this was one of the first music videos to feature substantial production value and investment, making it worldwide famous and setting a trend that would influence the industry for decades. Other unforgettable examples from the era include the animated masterpiece "Take On Me" by A-ha (1985) and the vibrant aerobic-themed "Physical" by Olivia Newton-John (1981).

While music videos remain a key part of the music industry today, they’ve evolved to be shorter and more dynamic, often prioritizing quick impact over storytelling.

Synthesizer Sound

One of the most iconic and recognizable features of '70s and '80s music is the use of synthesizers.

First introduced in the 1960s, synthesizers grew in popularity over the following decades, until they became part of nearly every sound of the era—from rock and funk to pop, disco, and electronic music.

A great '70s example is Stevie Wonder 's "Superstition," which showcases the innovative use of synthesizers. By the '80s, the synthesizer sound had reached new heights, thanks to bands like Depeche Mode and Duran Duran , who helped define the decade's musical identity.

5

Disco Balls

If there's one thing that screams 1970s, that's undoubtedly disco music. With icons like the Bee Gees, KC The Sunshine Band, and Donna Summer, disco emerged in America and quickly got the whole world onto the dance floor.

In addition to platform shoes and satin shirts, one of the objects that went hand in hand with this type of music was the famous mirror ball, also called the disco ball. Discotheques often showcased spectacular disco balls, and famous artists included them in their music videos, making those shiny spheres the stars of the era.

6

Roller Skates

Image: Nick Fewings

Disco wasn’t the only sensation of the era—roller skates were a big deal, too. In fact, the two often combined: during the '70s and '80s, roller discos became a hit, where people danced on wheels!

Roller skates were so popular at the time that they made their way into films and music videos, including the 1980 cult classic Xanadu and Cher’s iconic 1979 music video for "Hell on Wheels."

Although roller skates were invented in the 18th century, it was the 20th century that catapulted them to the height of their fame. Were you lucky enough to strap on a pair and join the fun?

7

Arcade

If you were young in the '80s, you probably had a joystick or an arcade token in your hands, as arcades were the ultimate hangout spots for teenagers back then.

We bet you remember titles such as "Space Invaders," released in 1978, or the legendary "Pac-Man," which arrived to revolutionize the entire industry in 1980. Other unforgettable classics included "Donkey Kong" and "Frogger," both released in 1981.

So, what was your high score? Did you dominate the leaderboard or keep coming back for just one more game?

Atari 2600

What do you usually do when you're bored at home? For most of us, it's watching a movie or scrolling through our phone screens. But a few decades ago, the entertainment industry looked entirely different.

In 1977, home recreation changed forever with the arrival of the Atari 2600, one of the first home gaming consoles. From that moment on, gamers could enjoy their favorite games without ever leaving the comfort of their homes.

9

Slang

But it wasn't just about fashion, music, and games. We can't forget the prominence of slang during these two emblematic decades.

One of the first terms that comes to mind is "groovy," remember that one? It was used to describe something cool or excellent. Maybe you remember a friend saying, "I love your outfit, super groovy!" Another memorable expression from the era was "Gag me with a spoon," used to convey disgust or displeasure, as in "That's so cheesy! Gag me with a spoon!"

Other unforgettable slang words included "bummer," "rad," "hip," and "tubular," each capturing the spirit of the '70s and '80s in its own unique way.

Cabbage Patch Dolls

If you didn't have one at home, you probably knew someone who did—or maybe even had more than one. We're referring to the famous Cabbage Patch Dolls, the toy that caused a sensation during the early 1980s.

Launched in 1982, the Cabbage Patch Dolls quickly made their way into most American homes. Their popularity was so massive and abrupt that they are remembered as one of the most iconic trend crazes of the 20th century. People would form long lines outside toy stores just to hug one of these dolls. In fact, the craze was so intense that the media dubbed it the "Cabbage Patch Kid Frenzy."
