Say cheese!

Did you know American cheese is not actually cheese?

Few foods trigger as much heated debate as the neon-orange, perfectly square slice of American cheese. To culinary purists, it’s an industrial piece of rubber. But to the backyard grill master and the late-night grilled cheese enthusiast, it is a scientific masterpiece of consistency and meltability. The truth is, American cheese has been both witness and party to U.S. history, from World War I to Apollo missions. Before you peel back the wrapper on your next slice, let’s dive into 10 mind-melting facts that prove American cheese is one of the most fascinating—and misunderstood—innovations in food history.

1
It was invented in Switzerland

While the name suggests a US origin, the technology that created American cheese actually began in the heart of the Alps. It was developed in 1911 by Swiss researchers Walter Gerber and Fritz Stettler, who were looking for a way to extend the shelf life of their country’s famous Emmental cheese.

The problem with traditional cheese is that it eventually dries out, molds, or separates into a greasy mess when heated. By shredding the cheese, adding sodium citrate, and heating it, the Swiss duo discovered they could create a stable, smooth product that didn't separate. While they weren't trying to create "American" cheese as we know it today, their emulsification process laid the foundational science for every single-wrapped slice produced today.

2
It was popularized by a Canadian

The man responsible for the global dominance of American cheese was James L. Kraft. Ring any bells? Kraft was a Canadian immigrant who moved to Chicago in 1903. While he didn't invent the concept of processed cheese, he perfected the industrial scale of its production and marketing.

Kraft noticed that retailers struggled with cheese spoilage; if a wheel of cheddar didn't sell quickly, it was a total loss. He experimented with various methods of heating and blending cheese until he found a formula that could be canned and shipped long distances without spoiling. In 1916, he received a patent for his "processed cheese," and during World War I, the U.S. government purchased millions of pounds of it for soldiers, cementing its privileged place in the American diet.

3
It was almost called "Embalmed Cheese"

When processed cheese first hit the market, it had its detractors. Traditional cheesemakers were horrified, and so were pure food advocates. These critics argued that the product shouldn't even be called cheese. They’ve even gone so far as to call it "embalmed cheese" because of its unnaturally long shelf life and the chemical emulsifiers used to keep it stable. Yet, Kraft’s marketing prowess and the sheer convenience of the product ultimately won the naming battle. At least in the court of public opinion.

4
Technically, it isn’t cheese

Kraft may have won the battle among the people, but legally, American cheese is not considered cheese. If you look closely at the packaging, you will rarely see the word "cheese" on its own. Because of strict FDA regulations, most varieties are legally classified as "Pasteurized Process Cheese Product" or "Pasteurized Process American Cheese Food."

To be labeled "cheese," a product must be made primarily of milk, salt, and enzymes. Processed American cheese, however, is made by blending real cheese—usually cheddar or Colby—with emulsifying salts, whey, and sometimes extra milk or fats.

5
Any cheese can be made into American cheese

The term "American cheese" refers more to a process than a specific flavor. In theory, you could make "American-style" brie, blue cheese, or parmesan. The defining characteristic is the addition of an emulsifier, which breaks down the proteins and allows the fats and water to stay together.

In fact, some high-end chefs now make their own artisanal American cheese with aged cheddars processed with sodium citrate to create a slice that has the complex flavor of an expensive block but the melting point of a Kraft Single.

6
It isn’t naturally yellow

Image: jianwei zhu

The vibrant orange-yellow hue of American cheese is entirely a cosmetic choice. Traditionally, cheese color varied by the season; when cows ate fresh grass in the summer, their milk contained more beta-carotene, leading to a naturally yellowish cheese. To make their cheese look high-quality all year round, cheesemakers began adding dyes.

American cheese takes this tradition to the extreme. It is typically colored with annatto, a seed from the achiote tree. Without this dye, American cheese would be a pale, creamy white, which is how it is sold in many delis as "White American". Yes, that’s right, there is no flavor difference between the white and yellow versions.

7
It has an extremely low melting point

Image: Vinícius Caricatte

The scientific superpower of American cheese is its meltability. Traditional cheeses have a protein structure that tightens when heated, which is why a slice of aged cheddar on a burger often results in an oily puddle and a rubbery clump.

Because of the emulsifying salts, the proteins in American cheese can withstand heat without clumping together. This gives it an incredibly low and stable melting point, transforming the slice into a silky sauce. This is why it remains the undisputed king of grilled cheese sandwiches.

8
It’s been in space

When you're hurtling through orbit in a cramped capsule, you need food that is stable, easy to eat, and won't crumble into thousands of tiny, electronics-clogging pieces. American cheese fit the bill perfectly for early NASA missions.

Processed cheese in tubes or cubes was a staple of the Apollo missions. Because it doesn't separate or sweat oil in varying temperatures and pressures, it was one of the few dairy products that could reliably provide flavor and calcium to astronauts.

9
It helped bring cheese to the masses

Image: Internet Archive Book Images, No restrictions, via Wikimedia Commons

Before the advent of processed cheese, cheese was often a seasonal luxury. It was difficult to transport, expensive to store, and highly variable in quality. James L. Kraft’s invention changed that. By creating a product that was uniform in flavor and shelf-stable, he made cheese affordable and accessible to every corner of the United States.

10
The U.S. Government once gave it out

The U.S. government not only bought tons of American cheese during World War I. In the 1980s, the term "government cheese" became a thing. During a period of dairy surpluses, the government bought millions of pounds of cheese to prop up prices for struggling farmers.

To avoid letting it rot, the Reagan administration began distributing five-pound blocks of cheese to low-income families, seniors, and schools. For many who grew up in that era, that pale orange processed cheese was a lifesaver.

Hidden stories

The secret WWII project hidden beneath the White House

Did you know the White House wasn’t originally meant to be white? Or that hidden underground spaces were built beneath it? For more than 200 years, we have seen the White House in movies, on the news, in family photo albums from Washington trips, and during some of the biggest moments in our country’s history. But behind those famous walls are stories most have never heard. From fires and secret construction projects to strange traditions and forgotten moments, these are 10 surprising White House stories that most of us were never taught in school.

1
It was almost completely torn down

Image: Abbie Rowe, Public domain, via Wikimedia Commons

Did you know that very little of today’s White House interior is actually original? Looking at the building now, it’s hard to imagine that it was once so unstable that it was in danger of collapsing.

By 1948, after decades of heavy use, outdated wiring, poor structural supports, and years of renovations layered over one another, the White House had become unsafe. Floors and walls cracked, and parts of the residence were literally sinking. President Harry S. Truman even joked that the place felt haunted because it made so many strange noises. Rather than abandon it, Truman launched a massive reconstruction project with Congress. Between 1948 and 1952, nearly the entire interior was gutted and rebuilt while the original exterior walls were preserved, giving America a strong and reliable White House.

During WWII, they built an underground bunker

Did you know there’s a fortified bunker hidden beneath the White House? A couple of years before Truman’s famous renovation, another major project was quietly built beneath the presidential residence.

In 1942, during World War II, President Franklin D. Roosevelt ordered the construction of a secure underground shelter to protect government leaders in case Washington, D.C., came under attack. Built quickly and in great secrecy, the bunker was completed within months, though it was luckily never needed during the war. Today, the facility is known as the Presidential Emergency Operations Center, or PEOC, and it was famously used in 2001 by President George W. Bush and again in 2020 by Donald Trump.

It was not originally meant to be white

Can you imagine if it were called "the Gray House"? Today, it’s impossible to picture America’s most famous home as anything other than bright white, but that wasn’t the original idea.

During construction in the 1790s, workers covered the exterior sandstone with a lime-based whitewash to protect it from moisture, cracking, and harsh winter weather. The coating gave the building a pale grayish appearance, not the brilliant white we recognize today. A long-standing myth claims the White House was painted white to hide the burn marks left after British troops set it on fire in 1814, but in reality, the building had already been whitewashed years earlier. Still, after the fire and reconstruction, the white exterior became permanent and eventually inspired the famous name "White House," though for many years people still called it the "President’s House."

10 people have died in the White House

Many people have lived and worked in the White House over the centuries, but, according to the White House Historical Association, only 10 people are officially recorded as having died inside the presidential residence.

Among them were two U.S. presidents. William Henry Harrison died there at age 68 in 1841 after falling seriously ill, likely from contaminated water. Zachary Taylor died at age 65 in 1850 from a severe stomach illness after attending Fourth of July celebrations in extreme heat. Three First Ladies also passed away in the White House: Letitia Tyler in 1842, Caroline Harrison in 1892, and Ellen Axson Wilson in 1914. Other deaths included presidential relatives, aides, and staff members, among them Abraham Lincoln’s son, Willie Lincoln, whose death at the age of 11 in 1862 deeply affected the family and became one of the White House’s most heartbreaking stories.

5
Presidential whims

Not every White House renovation happened due to war, damage, or urgent repairs. Some changes came simply from the personal tastes and hobbies of the presidents who lived there, and over the years, there have been quite a few memorable ones.

In 1973, Richard Nixon installed a one-lane bowling alley beneath the North Portico. Years later, in 1989, George H. W. Bush added a regulation horseshoe pit near the White House grounds, where he often relaxed and challenged visitors, including Queen Elizabeth II, to games. Then, in 2009, Barack Obama had the South Lawn tennis court modified so it could also be used for basketball, one of his favorite sports.

6
Jackie Kennedy's furniture

When the Kennedy family entered the White House in 1961, the first lady was disappointed to find that many of the historic rooms had lost much of their original character.

Determined to restore the White House’s history and elegance, Jackie Kennedy famously launched a massive restoration effort. She helped create the White House Fine Arts Committee, brought in historians and curators, and filled the residence with genuine antiques and historical pieces tied to past presidencies. On February 14, 1962, an estimated 46 to 56 million people tuned in to watch the First Lady’s televised tour of the White House, making it one of the most-watched programs of its era. She also supported a congressional act that made many of the White House’s historic furnishings official property of the nation, so future presidents could no longer sell, replace, or discard them.

7
Official name changes

As we mentioned, the building was not always white, and therefore was not always officially called the White House. For much of the 19th century, Americans usually referred to it as the "Executive Mansion" or the "President’s House." Even after its famous white exterior made the nickname popular, it still was not the building’s official name.

That finally changed in 1901, when Theodore Roosevelt began printing "The White House" on presidential stationery. According to official sources, Teddy Roosevelt preferred this name because it clearly separated the president’s residence from the many state "executive mansions" used by governors across the country.

8
It was once America's largest house

There is one thing about the White House that no one can deny: it has always been huge, even in its early days.

When the White House was first occupied in 1800, it already contained more than 100 rooms spread across three floors, making it one of the grandest homes in the United States at the time. In a time when most Americans lived in modest houses or farms, the presidential residence was seen as a palace. Many historians even consider it the largest private residence in the country during its early years. Today, the White House covers about 55,000 square feet, though modern private buildings, like the Biltmore Estate in North Carolina, are now far larger.

President Benjamin Harrison’s fear

Among the many changes the White House has undergone over the years, few were as revolutionary as the arrival of electricity.

For nearly a century after it was built, the presidential residence relied on candles, oil lamps, and gas lighting. That finally changed in 1891, when electricity was installed during the presidency of Benjamin Harrison. But, like many families in that era, the Harrisons were not exactly thrilled by this modern invention. According to White House stories passed down over the years, President Harrison and First Lady Caroline Harrison were so nervous about the possibility of electric shock that they rarely touched the light switches themselves. Instead, they often asked the house staff to turn the lights on and off for them.

10
Hillary Clinton’s special gift

Image: Ralph Alswang, Public domain, via Wikimedia Commons

Of course, Jackie Kennedy wasn’t the only First Lady to leave her mark on the White House. Hillary Clinton added her own personal touch as well, this time as a gift for her husband.

In 1996, Hillary Clinton transformed a little-used room on the White House’s third floor into a private music room for President Bill Clinton. The gift came during the year of Bill Clinton’s 50th birthday and reflected one of his best-known passions: music. Complete with space for listening to records and playing his famous saxophone, the room gave the president a quiet retreat inside the White House.

Sin City’s secrets

Fascinating facts about Las Vegas you won't find on travel guides

Image: Paul IJsendoorn

A man once sold every single thing he owned, flew to Las Vegas, and bet the whole lot on a single spin of the roulette wheel. Do you think he won? There are 600 miles of concrete flood tunnels under Sin City—can you estimate how many people live there? Most of the profits of the whole city come from one single game; could you guess which one it is? Read on to find all the answers to these stunning facts about Las Vegas, Nevada.

1
The man who sold everything he owned and bet it all on one spin

Image: Pavel Danilyuk

In 2004, a 32-year-old British man named Ashley Revell walked into the Plaza Hotel and Casino in Las Vegas and placed every dollar he had in the world on a single spin of the roulette wheel.

In the months before, Revell had sold his house in Kent, his BMW, his Rolex watch, his golf clubs, his electronics, his furniture, and every piece of clothing he owned. The grand total of his liquidated possessions came to $135,300 . He pushed the entire stack of chips onto red as the ball was already spinning. It landed on Red 7.

Revell walked away with $270,600, exactly double what he had come in with. He tipped the croupier $600 on the way out. The whole thing was filmed by Sky One for a reality mini-series called Double or Nothing .

2
Beneath the casinos, an estimated 1,500 people live underground

Image: Stephen Leonardi

Below the glittering hotels and neon lights of the Las Vegas Strip runs a network of concrete flood drainage tunnels stretching roughly 600 miles beneath the city. Built in the 1990s to manage flash flooding in the Nevada desert, these tunnels have become an unofficial home for hundreds of the city’s unhoused residents.

It is estimated that between 1,200 and 1,500 people live there . Some residents have constructed makeshift shelters from plywood and salvaged metal deep inside the tunnels, occasionally just yards below the casino floors above them.

The tunnels pose serious dangers: flooding risk during desert rainstorms, extreme heat, and high rates of substance abuse. A network of nonprofits, outreach teams, and government agencies coordinates aid by providing the residents with essentials and offering them long-term case management, like treatment and housing placement.

3
Las Vegas has a literal black book of people banned for life

Image: BehindTheTmuna

Since 1960, the Nevada Gaming Control Board has maintained what it officially calls the List of Excluded Persons, better known as the Black Book. The original publication was a black-covered booklet held together with Scotch tape, listing eleven people deemed to have "notorious or unsavory reputations."

Most of the early entries were organized crime figures: Chicago outfit boss Sam Giancana; enforcer Anthony "Tony the Ant" Spilotro, whose violent exploits inspired Joe Pesci’s character in the film Casino ; and nine other mob associates. Anyone whose name appears on the list is permanently banned from entering any licensed gaming establishment in the state of Nevada.

Violating the ban is a gross misdemeanor under Nevada law. As of 2026, there are 37 names on the list. No one has ever successfully appealed their removal.

Strange casino rules: no clocks, no windows, no soft dice

Image: Elizabeth Ferreira

Las Vegas casinos are designed to keep gamblers at the tables as long as possible. Clocks are banned to distract players from the passing of time. Windows are eliminated so that they cannot tell whether it is noon or 3 a.m.

What’s more, Nevada law governs even the dice. The Nevada Gaming Control Board requires casino dice to be perfectly transparent so that no hidden weights can be concealed inside . Each die must be precision-manufactured to within 1/10,000th of an inch, with razor-sharp corners and edges showing no rounding whatsoever. They are inspected regularly and, in high-stakes games, replaced every eight hours of play to ensure consistent rolls.

5
The famous Las Vegas Strip is not actually in Las Vegas

Image: David Lusvardi

The stretch of Las Vegas Boulevard South that the world knows as the Strip does not lie within the city limits of Las Vegas. This is the area that’s home to Caesars Palace, the Bellagio, MGM Grand, the Venetian, Mandalay Bay, and dozens of other iconic venues.

Technically, it falls within an unincorporated community called Paradise , which is governed by Clark County rather than the city of Las Vegas. Paradise was deliberately established in 1950, when casino owners moved to avoid Las Vegas city taxes and regulations while continuing to trade on the city’s name and benefit from its infrastructure.

The city of Las Vegas actually begins further north along the boulevard, near the Stratosphere. Paradise covers approximately 54 square miles and has a residential population of around 220,000 people, which means it’s one of the largest and most densely populated unincorporated communities in the United States.

The Luxor’s sky beam is the most powerful artificial light on earth

Rising straight up from the apex of the black pyramid-shaped Luxor Hotel and Casino, the Luxor Sky Beam has been one of the most recognizable sights in Las Vegas since the hotel opened in October 1993. It is, by any measure, the most powerful artificial light beam on the planet. The beam is produced by 39 individual xenon lamps, each with 7,000 watts and roughly the size of a washing machine, focused through computer-designed curved mirrors into a single concentrated column.

Together, they generate an estimated 42.3 billion candlepower. On a clear night, airline pilots have reported seeing the beam from as far as 250 miles away. The total operating cost, confirmed by Luxor engineer John Lichtsteiner, is $51 per hour, of which $20 is electricity. That adds up to $480 a day only for lighting the signature beam each night —or $175,200 a year.

Las Vegas is home to the tallest observation tower in the US

Image: Dave Morgan

Standing 1,149 feet above the Las Vegas valley, the Strat Tower, officially rebranded from the Stratosphere in 2020, is the tallest freestanding observation tower in the US and the second-tallest in the entire Western Hemisphere, surpassed only by the CN Tower in Toronto at 1,815 feet. It is also the tallest building in Nevada and the tallest structure west of the Mississippi River.

At the top, the Strat offers four outdoor thrill rides, including one that dangles riders 64 feet beyond the edge of the building on a mechanical arm, over 900 feet above the ground.

8
Slot machines account for around 60% of all casino revenue

Image: Elizabeth Ferreira

Walk into any Las Vegas casino, and the first thing that surrounds you (and the loudest) is the rows of slot machines that line nearly every available wall and corridor. That layout is not a coincidence.

It is estimated that slot machines consistently generate approximately 60 to 65 percent of all casino gaming revenue in Nevada. There is roughly one operating slot machine for every eight residents of Las Vegas. Nevada law requires that video slot machines pay out a minimum average of 75 percent, though Strip machines in practice typically return 87 to 97 percent.

Casinos place the most visible, most tempting machines near entrances, elevators, and high-foot-traffic corridors , a placement strategy that has been studied and refined over decades. Despite the rise of poker rooms and sports betting in recent years, slot machines have remained the single largest source of gaming income in Las Vegas without interruption for more than half a century.

9
The gambling capital of the world does not sell lottery tickets

Image: Obi

Nevada is one of only two states in the entire United States that have no state lottery, the other being Utah. You cannot legally walk into a convenience store and buy a $2 scratch-off ticket.

The reason is straightforward and has nothing to do with moral opposition. Nevada’s gaming industry has lobbied persistently and successfully against a state lottery since gambling was first legalized in 1931, on the grounds that a government-run lottery would directly compete with casino revenues.

FedEx was saved from bankruptcy by a Las Vegas blackjack table

Image: Joshua Santos

In 1971, FedEx, then called Federal Express, was days away from collapse. Founder Frederick W. Smith had built the company on the revolutionary idea of overnight package delivery using a central hub-and-spoke air network, but the business was not working.

The company had roughly $5,000 left in its operating account. It was not enough. Facing what appeared to be the end, Smith flew to Las Vegas and sat down at a blackjack table. He gambled the company’s last $5,000 and turned it into $27,000, which was just enough to cover that week’s fuel costs and keep the planes in the air. The breathing room bought by that blackjack session gave Smith enough time to secure additional financing. Today, FedEx employs more than 500,000 people worldwide and is valued at over $60 billion.
