Coca-Cola

A beverage so iconic that it inspired an entire genre of soft drinks named after it, Coca-Cola had its start in 1886 when it was created by pharmacist John Pemberton, who initially intended to market it as a temperance drink and medicinal tonic.

A blend of coca leaves and kola nuts (a source of caffeine), the iconic soft drink became a sensation, and soon Pemberton sold the ownership rights to Asa Griggs Candler, a businessman who transformed the Coca-Cola brand into a global powerhouse. While the ingredients have been changed a few times since its inception, the current formula remains a closely guarded trade secret, fueling much speculation and numerous attempts to uncover it.

Pepsi

Developed in 1898 by pharmacist Caleb Bradham—and originally named "Brad's Drink"—Pepsi was initially conceived as a digestive aid. Its name is derived from pepsin, a digestive enzyme produced by the body, though pepsin was never actually included in the drink's formula.

Despite nearly going bankrupt in the early 1920s, Pepsi gained popularity during the Great Depression, even briefly outpacing Coca-Cola, thanks to clever marketing that appealed to budget-conscious consumers. This kickstarted a fierce rivalry, leading to bold marketing stunts, including an unlikely deal with the Soviet Union, making Pepsi the first Western product sanctioned for sale there.

Dr Pepper

Another soft drink originally conceived in a pharmacist's lab, Dr Pepper actually predates both Coke and Pepsi. Launched in 1885 in Waco, Texas, its unique flavor sets it apart from most competitors. In fact, the U.S. Food and Drug Administration has categorized Dr Pepper, much like Coca-Cola, as its own distinct type of beverage: "pepper soda."

The origin of its name is disputed. Originally, people would simply order a "Waco" at soda fountains. While some speculate the name comes from Charles T. Pepper, a doctor who gave Wade Morrison his first job (or, according to another version, gave him permission to marry his daughter), it was more likely than not a creative marketing decision, as using "Dr." in product names was a common way to suggest health benefits.

7UP

7UP, created in 1929 by Charles Leiper Grigg, was originally marketed as "Bib-Label Lithiated Lemon-Lime Soda," as it contained lithium citrate (a mood-stabilizing drug) among its ingredients. While lithium was removed in 1948, the drink's refreshing lemon-lime flavor remained, having already become a household favorite.

The soft drink, however, didn’t quite find its market niche until it launched the "Uncola" marketing campaign in the 1970s, which positioned the soda as a distinct alternative to colas, boosting its popularity. The origin of the name 7UP remains a mystery, with speculation that it refers to the original 7-ounce bottles or the drink’s initial seven ingredients.

Sprite

Introduced by Coca-Cola in 1961 to compete with 7UP, Sprite quickly became one of the leading lemon-lime sodas on the market. Interestingly, this popular soft drink didn’t originate in America but in West Germany in 1959, where it was launched as "Fanta Klare Zitrone" ("Fanta Clear Lemon" in English).

In the ‘80s, Sprite leveraged its appeal to younger generations through bold advertising campaigns and endorsements from popular musicians. Today, the brand has expanded into various flavors, including cranberry, cherry, grape, orange, tropical, ginger, and vanilla, among others.

Mountain Dew

Mountain Dew was originally created in the 1940s by Tennessee beverage bottlers Barney and Ally Hartman as a mixer for whiskey. The name "Mountain Dew" was a colloquial term for homemade liquor, making it fitting for the soda’s Appalachian roots. However, the drink only took on its citrus-flavored, energizing modern form after being acquired by the Tip Corporation in 1961.

It remains one of the most caffeinated sodas on the market, containing 54 mg of caffeine per 12-ounce can—nearly double that of Coca-Cola. This is likely what draws many soda drinkers to this flavor, as the high sugar and caffeine content can give a short-term boost of energy.

7

RC Cola

Founded in 1905 by Claud A. Hatcher, Royal Crown Cola (RC Cola) was originally created as a direct competitor to Coca-Cola and Pepsi. The soft drink was born after the Hatcher family, who were grocery store owners, could not get a discount for purchasing large volumes of Coca-Cola syrup from local distributors. Frustrated, they vowed to create their own alternative.

Despite never achieving the same market dominance as Coke or Pepsi, RC Cola soon gained a loyal following, especially in Southern states. Unlike its rivals, RC offered a slightly stronger cola flavor, which many found refreshing compared to the sweeter taste of Coke. RC Cola also innovated with the first aluminum can for sodas and was one of the first companies to produce diet sodas, such as Diet Rite.

Fanta

Did you know that Fanta was born in Germany during World War II, of all places? After local Coca-Cola plants could no longer import syrup due to trade embargos, German businessman Max Keith created a new soda using available ingredients—which were mostly fruit scraps and whey.

Fanta quickly became a wartime favorite in Germany. After the war, Coca-Cola regained control of the plant, formula, and trademarks, introducing Fanta to the U.S. in 1955. It rapidly gained popularity as a fun, fruit-flavored alternative to traditional sodas. While Fanta's orange flavor remains its best seller, the brand now offers over 90 flavors worldwide.

A&W Root Beer

A&W Root Beer was introduced in 1919 by Roy Allen, who first started selling it at a parade honoring returning World War I veterans. Its creamy texture and rich flavor quickly made A&W Root Beer a favorite, especially when paired with vanilla ice cream to create the now-iconic root beer float.

By 1922, Roy Allen partnered with fellow entrepreneur Frank Wright, and A&W became a franchised brand, launching one of the first fast-food chains in America that same year. Despite struggling with labor shortages and sugar rationing during World War II, the company endured and remains one of the most iconic root beer brands in America to this day.

Sunkist

Sunkist, launched in 1979 by the Sunkist Growers cooperative, was introduced to tap into the American love for citrus-flavored sodas. Known and loved for its bold orange flavor, Sunkist was the first major orange soda to include caffeine in its formula, setting it apart from competitors like Crush and Fanta.

Most importantly, Sunkist's success was greatly boosted by its association with the California citrus industry. Its marketing campaigns, including the "Taste the Sun" slogan, further linked the brand to sunny, vibrant outdoor activities, making it one of the top-selling orange sodas in the U.S. for decades.

Dry Tortugas National Park, Florida

Located about 70 miles west of Key West, Dry Tortugas National Park is one of the most isolated national parks in the country , accessible only by ferry or seaplane. About 99% of the park is water. Its main landmark is Fort Jefferson, a massive unfinished 19th-century coastal fort built with more than 16 million bricks.

Visitors often go for a day trip, but camping is available for those looking for an overnight experience. The park also offers snorkeling, swimming, and birdwatching.

2

White Sands National Park, New Mexico

White Sands National Park protects the world’s largest gypsum dune field, covering about 275 square miles in southern New Mexico. Here is the difference between gypsum and typical sand: the former does not absorb heat the same way, so the dunes remain relatively cool underfoot, even in hot weather.

The park is known for activities like dune sledding, hiking marked trails , and scenic drives through the shifting landscape. While its distance from major cities means it stays less crowded than others, the park is still easily accessible by car.

3

Big Bend National Park, Texas

Big Bend National Park covers more than 800,000 acres along the Rio Grande, which forms the natural border between the United States and Mexico. It’s one of the least visited national parks of its size, largely because of its remote location in southwest Texas.

Those who visit come for the Ross Maxwell Scenic Drive, hikes into Santa Elena Canyon, and some of the best stargazing in the country. The Greater Big Bend International Dark Sky Reserve, spanning over 15,000 square miles, is the world’s largest certified "Dark Sky," an area where light pollution is regulated to preserve wildlife, aid astronomical research, and allow visitors to enjoy a stunning night sky.

4

Pinnacles National Park, California

This national park might be one of the newest —it was designated in 2013—, but that doesn’t mean that its unique rock formations are recent. They were created by an ancient volcanic field that has shifted over millions of years.

The park is best known for its talus caves, one of the few places where you might spot the endangered California condor in the wild. Located about 80 miles southeast of San Jose, it’s relatively accessible but still far less crowded than parks like Yosemite .

5

Isle Royale National Park, Michigan

This island sits on Lake Superior and is one of the least visited national parks in the United States, receiving only a small fraction of the visitors seen at major parks. It’s only accessible by ferry or seaplane, and has no roads or cars.

This makes it an ideal destination for hikers, backpackers, and kayakers. Keep in mind, though, that the park is only open from mid-April through October due to harsh winter conditions.

6

Mammoth Cave National Park, Kentucky

Mammoth Cave National Park protects more than 400 miles of mapped underground passages . That makes it the longest cave system in the world —and scientists believe there are hundreds of miles left to be discovered.

Guided tours are available, ranging from easy walking routes to more physically demanding crawls. Even above ground, the park offers hiking, biking, and canoeing along the Green River.

7

Voyageurs National Park, Minnesota

Voyageurs National Park is named after French-Canadian fur traders who once traveled these waterways. It is made up of nearly 40% water, with a network of interconnected lakes along the Canadian border. That means you can explore it by boat, kayak, or canoe.

Its isolation and lack of light pollution also make it ideal to enjoy gorgeous night skies —to gaze at the stars, the Milky Way, or even the Northern Lights.

8

North Cascades National Park, Washington

North Cascades National Park is one of the most glaciated areas in the contiguous US, with around 300 glaciers. Located about a three-hour drive from Seattle, it remains one of the least visited national parks, largely because it lacks the easy roadside viewpoints found in places like Yellowstone.

Its highlights include Diablo Lake and the Cascade Pass trail. Summer and early fall offer the best access, as many roads and trails are closed by snow in winter.

9

Wrangell-St. Elias National Park and Reserve, Alaska

Wrangell–St. Elias National Park and Preserve spans about 13.2 million acres. That means it’s larger than Yellowstone, Yosemite, and Switzerland combined . The park includes some of North America’s tallest peaks, massive glaciers, and historic mining sites like the Kennecott Copper Mine. Most travelers can explore it via small aircraft, guided tours, or long-distance hiking trips.

10

Petrified Forest National Park, Arizona

Petrified Forest National Park is known for its large deposits of petrified wood, trees that lived over 200 million years ago and have since turned to stone. The park also includes sections of the Painted Desert, with layered rock formations in shades of red, purple, and orange . It can be easily explored by car, with a scenic drive connecting major viewpoints and short trails.

The moon landing: staged in Arizona?

Image: NASA

Back in 1969, Americans watched Neil Armstrong take one small step for man on TV. But not long after, rumors started floating around that it was all filmed on a Hollywood-style set somewhere in the desert. Books and even a movie helped the idea spread. Still, with hundreds of pounds of moon rocks and decades of scientific study to back it up, it seems pretty clear the only thing fake was the rumor itself.

The dead internet theory: bots gone wild

Image: Waldemar

According to this theory, you might be talking to a wall online. The idea is that most of the internet isn’t run by people at all but by bots—that is, automated programs pretending to be humans. They supposedly post, reply, and argue, all to keep clicks coming. Even if bots are increasingly popular on some sites and apps, it’s evident that this is nothing but a crazy conspiracy theory!

Subliminal advertising: blink and you’ll miss it

Image: Wojtek Witkowski

Remember when people thought ads were sneaking messages into our brains? Some authors were convinced that companies were hiding secret images in movies and commercials to mess with our minds. This theory hit headlines in the ’70s, but most of those claims didn’t hold up under scrutiny. Marketing and advertising do know some tricks around our minds, but your sudden craving for popcorn probably has more to do with the smell than secret mind control.

Paul is (not) dead

Image: IJ Portwine

Back in the swinging ’60s, a bizarre rumor began circulating: Paul McCartney had supposedly died and been replaced by a lookalike. Fans claimed to find hidden clues in Beatles albums, like barefoot walks and cryptic lyrics. The theory quickly crossed borders and spread worldwide. But don’t worry, Paul was (and still is) very much alive, touring, and giving interviews.

Roswell: crash course in confusion

Image: Rishabh Sharma

Something definitely fell near Roswell, New Mexico, in 1947—remember that? The question is, what was it? The government first hinted at flying saucers , then changed the story to a weather balloon. That was all it took for conspiracy theories about aliens to bloom. Years later, it turned out the object was actually a Cold War–era military balloon from a classified program. No aliens—just some top-secret tech.

6

Chemtrails: clouds of confusion

Image: Val Vesa

Those streaks behind planes? They’re called contrails, and they’re mostly made of water vapor. But some believe they’re really "chemtrails" (chemical agents sprayed into the sky). Theories range from weather control to population mind games. Scientists have tested the air and found nothing unusual, but some folks still keep looking up and wondering. What do you think?

7

COVID and 5G: a confusing combo

Image: Shiwa ID

When the pandemic hit, it brought more than just a virus. With so much uncertainty, conspiracy theories spread just as fast. One unusual claim linked COVID-19 to 5G technology, even suggesting that vaccines contained tracking chips. Researchers and doctors around the world quickly debunked it all, but it just goes to show how fear and confusion can breed some pretty wild ideas.

8

Birds aren’t real... or are they?

Image: Gareth Davies

This one takes the cake. A satirical movement claims that birds are actually government surveillance drones . What started as a joke by a college student quickly went viral, billboards and all. While some people mistook it for a real conspiracy theory, it’s actually a commentary on how misinformation spreads.

Flat Earth: going against the grain

Image: Elena Mozhvilo

Despite centuries of science and countless space photos, some people still believe the Earth is flat . They point to the horizon, question gravity, and invent creative explanations for eclipses and orbits. It’s a belief often fueled by mistrust or ideology, but the round Earth, seen from space, keeps on spinning just the same.

Denver Airport: baggage and bunkers

Image: Rocker Sta

Denver’s airport has some… interesting décor. Murals of chaos, red-eyed horses, and creepy gargoyles have sparked rumors that it’s hiding secret bunkers for the Illuminati. While the truth is less exciting (just over-budget construction and bold public art), the place does have a weird vibe that fuels the fun of imagining a secret space beneath the baggage claim. If only!
