The Pig War (1859)

A boundary dispute on San Juan Island nearly escalated into a U.S.-British war after an American farmer shot a British-owned pig that was rooting in his garden . Troops rushed in, tensions rose, and both sides came to the verge of open conflict.

Thankfully, the "war" ended without a single human casualty. Diplomacy prevailed, leaving history with a famously absurd standoff where the only fatality was the unfortunate hog that started it all.

2

The Toledo War (1835-36)

Believe it or not, Michigan and Ohio once squared off over a slim strip of land containing the city of Toledo . Militias mobilized, tempers flared, and political rhetoric soared past anything that the dispute really deserved.

The conflict produced only one injury: a sheriff was stabbed with a pocket knife. It ended with Michigan receiving the Upper Peninsula as compensation.

3

The Aroostook War (1838-39)

A mix of lumberjacks, militias, and confused officials sparked a border showdown between Maine and British Canada. Though the name sounds dramatic, the "war" consisted mostly of shouting, arrests, and paperwork .

Still, it lasted less than a year and recorded no combat deaths. Its odd blend of frontier folklore and diplomatic missteps gave it a reputation as one of America’s most harmless "wars."

4

Battle of Lake Erie (1813)

In a fierce naval engagement that lasted only a few hours, Commodore Oliver Hazard Perry secured control of Lake Erie during the War of 1812 . His quick, decisive victory shifted momentum in the northern theater of the war.

The battle is remembered for its speed and for Perry’s bold message: "We have met the enemy, and they are ours."

5

Battle of Blair Mountain (1921)

For five tense days in West Virginia, thousands of coal miners armed themselves against hired gunmen, local law enforcement, and eventually federal troops . It became the largest labor uprising in U.S. history.

Despite its scale, the conflict ended quickly once the Army intervened. Its strange blend of union struggle, machine guns, and biplanes made it one of the most dramatic yet short-lived labor battles ever fought.

6

Battle of Athens, Tennessee (1946)

World War II veterans took matters into their own hands and clashed with a corrupt county political machine after years of election wrongdoing. In a single night of gunfire and sieges, the veterans seized the jail and exposed the fraud .

By morning, order was restored and democracy reclaimed. The brief uprising became a legendary example of ordinary Americans pushing back against local tyranny.

7

Shelling of Fort Stevens (1942)

During World War II, a Japanese submarine surfaced off the Oregon coast and fired on Fort Stevens for roughly fifteen minutes . The startled gunners held their fire to avoid revealing their positions.

No lives were lost, and damage was minimal. Still, the brief attack stands out as one of the only direct assaults on the U.S. mainland during the war.

8

Battle of Palmito Ranch (1865)

Fought in Texas weeks after the Confederacy had effectively collapsed, this short skirmish featured U.S. and Confederate troops battling despite the war’s official end . Confusion and poor communication kept the fighting alive.

The engagement lasted only a few hours but became the Civil War’s final battle. Its odd timing makes it a historical footnote with a bizarre twist.

9

Battle of Ambos Nogales (1918)

A border misunderstanding escalated into a sudden firefight between U.S. and Mexican troops in the twin towns of Nogales, Arizona, and Nogales, Sonora. The shooting lasted only a few hours but drew civilians into chaos.

The brief clash prompted both governments to rethink border security. It remains the only World War I-era battle fought on U.S. soil involving foreign troops .

10

The Great Locomotive Chase (1862)

Union raiders stole a Confederate locomotive and sparked a dramatic pursuit through northern Georgia. The "battle" unfolded across railroad tracks and small towns over the course of a few hours.

Though unconventional, it was officially a military operation and became legendary for its daring and scope. The episode showed how even a train theft could become an act of war.

11

Little Belt Affair (1811)

This brief naval encounter between USS President and HMS Little Belt lasted less than an hour. Confusion over signals led to sudden gunfire and heavy damage to the British vessel.

The brief clash worsened tensions between the two nations and helped push the U.S. and Britain toward the War of 1812.

Singing Tesla coils

In the early 2000s, engineers discovered that Tesla coils could emit tones by modulating the sparks themselves. When programmed, they could play songs using bursts of lightning as notes.

Audiences watched and listened as glowing bolts of electricity "sang" familiar tunes like movie themes. These displays, part science and part spectacle, were a short-lived trend, but they were interesting while they lasted.

Franklin’s glass armonica

Benjamin Franklin invented many things. Among them, a glass armonica, using spinning glass bowls tuned by size . Players touched the rims with wet fingers to produce pure, haunting tones that seemed to shimmer in midair.

Its ghostly beauty amazed 18th-century audiences. Yet rumors spread that the vibrations could cause fainting or madness, making the momentum of the instrument short-lived.

Harry Partch’s microtonal instruments

Frustrated with the limits of Western scales, composer Harry Partch built a system using forty-three tones per octave . He crafted odd instruments from glass, bamboo, and metal to play them.

Performers had to relearn music from scratch, producing sounds that felt alien and ancient at once. His homemade orchestra became a true milestone in America’s experimental environment.

4

The theremin craze

Image: Ryunosuke Kikuno

Invented in the 1920s, the theremin created sound from invisible electromagnetic fields, played by moving hands through the air . It was one of the world’s first electronic instruments.

By the 1950s, its eerie wails filled American sci-fi movies and radio shows. Home versions soon appeared, letting living rooms buzz with strange, ghostlike melodies.

5

The Stroh violin

Back in the days when microphones were not so great at picking up sounds, early studios struggled to capture soft instruments. The Stroh violin solved that by replacing the wooden body with a brass horn that amplified sound directly .

Its brassy, nasal tone worked perfectly for primitive recording gear. Once technology advanced, the mechanical violin faded for good.

Sun Ra’s cosmic jazz

Jazz mad scientist Sun Ra claimed he was born on Saturn and sent to Earth to spread peace through sound. His Arkestra mixed free jazz, chants, and futuristic costumes into wild multimedia performances .

Audiences never knew what to expect: space helmets, electronic keyboards, or cosmic sermons. His blend of myth, science, and swing launched Afrofuturism, a style of his own.

Singing saw

Rural American musicians once discovered that a regular handsaw could "sing" when bent and bowed like a violin . The flexible steel vibrated with a haunting, "human-like" voice.

The sound carried through old-time folk, gospel, and early film scores. Even today, the singing saw appears in grassroots festivals and soundtracks.

Prepared piano

Image: Andrew Petrischev

Avant-garde composer John Cage inserted screws, bolts, and rubber between piano strings, turning each key into a new percussive sound . The result was bizarre but original.

He called it the "prepared piano." Audiences heard rhythms that clanged, thumped, and chimed like a whole percussion ensemble.

Moog synthesizer

Image: Adi Goldstein

The Moog was born in the late 1960s with its maze of knobs and wires , and it caused a sensation among musicians. Those who experimented found endless possibilities in its electronic tones .

From the Monterey Pop Festival to Wendy Carlos’s soundtracks for The Shining and A Clockwork Orange , the Moog’s strange bleeps reshaped American pop.

10

The Singing Nun

In 1963, a Belgian nun named Sister Luc-Gabrielle unexpectedly topped U.S. charts with "Dominique," sung in gentle French. Her purity and optimism charmed listeners across the country.

Her hit briefly outshone even the Beatles. Though her fame faded quickly, the story of a shy nun reaching number one remains a sweet oddity, for sure.

The "Longplayer" experiment

Launched in 1999, "Longplayer" is a music piece designed to play continuously for one thousand years without repeating . It was created by American artists who joined the project to maintain its endless cycle.

The music changes subtly with time, echoing life’s slow rhythm. Its creators call it "a conversation between centuries".

12

Hard-drive symphonies

Image: Borja Verbena

In the 2010s, hobbyists reprogrammed old computer drives to "play" songs by spinning and clicking at different speeds . Each tone came from mechanical motion, not speakers.

Videos of clattering machines performing pop hits can still be found all over YouTube. These homemade orchestras turned computer nostalgia into an art.

South Dakota sits right in the middle of it all

Image: Intricate Explorer

Just outside the town of Belle Fourche, South Dakota, lies the geographic center of the United States when you include Alaska and Hawaii . It is not marked with neon signs or big crowds, but there is something satisfying about standing near the heart of the whole country. It feels like the center of gravity for the U.S.

2

Iowa is flanked by rivers on both sides

Image: Justin Wilkens

If you look at a map, you will see Iowa neatly tucked between two mighty rivers . The Mississippi River borders it to the east, and the Missouri River forms most of its western boundary. No other state can say that its entire east and west borders are made up of rivers. That gives Iowa a front-row seat to river life from both sides.

3

Kansas is flatter than a breakfast pancake

Image: Edson Saldaña

Believe it or not, a group of researchers once compared Kansas to a pancake and found that Kansas is actually flatter . This was not a joke. They used real measurements. If long, open roads and wide horizons are your thing, Kansas is the ultimate smooth ride.

4

Arizona has all the deserts in one place

Image: Keith Hardy

Arizona is not just dry, it’s uniquely arid. It is the only state that includes parts of nearly all of the major North American deserts . These include the Sonoran, Mojave, Chihuahuan, and Great Basin deserts. That makes it a desert lover's dream and a living science exhibit where four very different ecosystems meet in one sunbaked state.

5

Michigan lives and breathes freshwater

Image: Aaron Burden

Michigan has more freshwater shoreline than any other state in the country. It borders four of the five Great Lakes , features two peninsulas, and is even home to a floating post office that delivers mail by boat. If you enjoy water views and lakeside life, Michigan delivers the goods in a big way.

Connecticut gave counties the pink slip

Image: Rusty Watson

Unlike most states, Connecticut does not have county governments. The state decided back in the late 1950s and early 1960s to get rid of them entirely. Now, counties are just lines on a map and have no political power. If you live in Connecticut, you deal directly with your town or city. No middleman needed.

7

Delaware still uses ‘hundreds’ and no, not the money kind

Image: Gary Cole

In Delaware, land is still divided into areas called hundreds . These are old British-style subdivisions that originally represented areas able to support roughly 100 households. While they do not play a role in law or government today, the names still show up in property documents and tax records.

Kentucky hides the longest cave under its feet

Image: Joshua Sortino

Beneath Kentucky’s surface lies a giant underground wonder called Mammoth Cave. It holds the record as the longest known cave system in the world , with over 400 miles of mapped tunnels. That is a whole lot of rock and mystery. Whether you are into history, geology, or just cool natural landmarks, this cave system is something special.

9

Louisiana prefers parishes over counties

Image: Joe Lavigne

Louisiana does not have counties like the rest of the country. Instead, it has parishes , a term carried over from its French and Spanish colonial days. These parishes work the same way counties do elsewhere, but the name gives the state a unique cultural twist.

10

Montana provides the nation's platinum and palladium

Image: Calvin Chai

Montana is the only significant source of domestically mined platinum and palladium in the United States. These rare metals are used in things like jewelry, dental tools, and car parts. Tucked into its rugged mountains, Montana’s mines quietly produce some of the most valuable materials in the country.

Wisconsin has an official microbe, and it makes cheese

Image: Azzedine Rouichi

Of course, Wisconsin would go this route. The state named Lactococcus lactis as its official microbe. It is the helpful little organism behind the cheese-making magic. Without it, you would not have cheddar, Colby, or many other favorites. Leave it to the dairy state to give a tiny cheese-maker its moment of fame.
