People have historically behaved irrationally when they’re of the belief that witches are about. In addition to holding trials and inspiring plays by Arthur Miller, the denizens of the past once went so far as to ban the humble potato because they believed it was linked to witchcraft. 

Everyone’s favorite tuber originated in the Americas and wasn’t introduced to Europe until the late 16th century, at which time potatoes were looked upon with fear and suspicion. Botanists identified the tubers as members of the poisonous nightshade family, leading to their association with devil worship and witchcraft. (While potatoes belong to the same family as deadly nightshades, they do not contain the same toxins.) They also aren’t mentioned in the Bible, which some religious thinkers of the time interpreted as a sign they weren’t meant to be eaten.

All of that was enough for France’s Parliament to outlaw potatoes from 1748 until 1772, when King Louis XV overturned the ban. The king was persuaded by a medical officer by the name of Antoine-Augustin Parmentier, who was fed little else during his time as a prisoner of war and found his confinement surprisingly tasty and nutritious. 

Elsewhere in food-related superstitions, Europeans spent centuries depriving themselves of tomatoes because they believed that tomatoes were poisonous. The pewter plates tomatoes were sometimes eaten on contained lead that was leached by the fruit, resulting in the misconception.

The Mississippi River once flowed backward for several hours.

As a general rule, rivers flow forward (which is to say, downhill) rather than backward. The mighty Mississippi is no exception, and yet a February 7, 1812, earthquake near New Madrid, Missouri, was so severe that it caused enough tectonic uplift under the river that it flowed backward for several hours. It was the most violent in a series of tremors that began in December of the previous year. Known as the New Madrid Earthquake Sequence, the tremors were the most powerful seismic event east of the Rockies in U.S. history.

The magnitude is estimated to have been 8.6 on the Richter scale, which occurs only once every year or two. For comparison, there are millions of earthquakes that measure 2.5 or less every year, 350 measuring from 5.5 to 6.0 annually, 100 that measure 6.1 to 6.9, and just 10 to 15 that hit between 7.0 and 7.9. The 8.6 earthquake knocked people off their feet, created so much rolling in the earth that it induced nausea, and destroyed Little Prairie, Missouri. Ten lakes were formed, church bells rang 1,300 miles away in Boston, and President James Madison even felt it in the White House. 

Ben Franklin proposed something like daylight saving time as a joke.

In most U.S. states, the clocks get set forward an hour on the second Sunday in March, making Monday morning arrive just a little too soon. While daylight saving time can seem like a cruel joke to groggy night owls, the concept is logical enough that even Benjamin Franklin suggested, albeit humorously, maximizing daylight by getting up earlier.

In 1784, when Franklin was living in Paris, he submitted a satirical letter to the Journal de Paris called “An Economical Project.” In it, he wrote that he was up late discussing ways to save money on lighting and went to bed around 3 a.m. or 4 a.m., before “[an] accidental sudden noise waked [sic] me about six in the morning, when I was surprised to find my room filled with light.”

Franklin, who was the author of Poor Richard’s Almanack, noted that he consulted his almanac and was “astonished” to find that the sun “was to rise still earlier every day till towards the end of June.”

In the letter, Franklin calculated that Parisian families could save millions of pounds by waking up with the sun and swapping candlelight for sunlight. He jokingly suggested levying a tax on closed shutters, setting limits on candle purchases, and ringing all church bells right as the sun rises — switching to cannons if the bells proved ineffective.

Franklin did not, even as a joke, suggest changing the time, but his letter was still somewhat prophetic. Ultimately, when countries started implementing daylight saving time, the main argument for doing so was fuel savings.

There was a lottery that gave you immunity from being arrested.

Get-out-of-jail-free cards aren’t exclusive to Monopoly. When Queen Elizabeth I found herself in need of funds to pay off the debts incurred by her father Henry VIII’s reign, she began organizing England’s first national lottery in 1567. One of the prizes was arguably worth more than money: immunity from being arrested. 

Elizabeth had been reluctant to raise taxes on her subjects despite her plans of expanding England’s naval forces and overseas expeditions, so she turned to a lottery instead. She wrote in a letter to Sir John Spencer in 1567, “It is expedient to have somme persons appointed of good trust to receave suche particular sommes as our subjects shall of their owne free disposition be ready to deliver upon the said lotterie.”

For the price of 10 shillings (about 120 pounds today, high enough to be cost-prohibitive for many citizens in Elizabethan England), entrants were eligible for a top prize of 5,000 pounds (around 1.1 million pounds today). The top 11 winners received cash prizes, and anyone who entered received temporary immunity from arrest for all crimes other than felonies, piracy, and treason — though this protection was not always enforced. The winners of that first lottery have alas been lost to history, but one imagines they enjoyed their low-stakes crime spree as much as, if not more than, their cash prize.

The ancient Romans had central heating.

The ancient Roman people used many technologies that seem surprisingly modern — including hypocausts, a precursor to central heating that’s similar to today’s radiant floors. The technique was primarily used to heat public bathhouses, but it was also widely used in private homes, particularly villas, in chillier areas of the Roman Empire. Buildings heated with a hypocaust system were raised up on pillars, creating an empty space underneath. An external furnace called a praefurnium, which was often wood-burning, piped in hot air to the area. That air would warm the stone or tile floor above, known as a suspensura. The air would escape from the subfloor through flues (sometimes made of terra-cotta) running up through the walls of a home, providing extra heat on its way up. Sometimes the entire wall would be hollow.

Pushing heat through the floors and walls helped keep Roman baths comfortable, preventing sudden temperature changes when entering or leaving warm water. Some rooms were simply heated with no water at all, designed for sauna-like dry sweating. But hypocausts also heated the water itself as it entered the facility. As the water dropped down from the aqueduct, it would immediately pass over a furnace chamber before being piped into the facility. As the water cooled, it could be used for tepid or cold baths in the complex. Hypocausts have been around for at least as long as Roman baths themselves; the technology may have been borrowed from the ancient Greeks and improved upon. This ancient heating system can be seen today at various surviving Roman baths, including the Stabian Baths in Pompeii, built around 125 BCE. 

Amman, Jordan, was once called Philadelphia.

There’s more than one city of brotherly love. Long before the Liberty Bell or cheesesteaks, Amman, Jordan, was known as Philadelphia, which comes from the Greek words phileo (“love”) and adelphos (“brother”). As one of the oldest continuously inhabited cities in the world — there’s evidence that people have lived there since the Neolithic Period — Amman has, unsurprisingly, been known by many names. Its current moniker derives from the ancient kingdom of Ammon, whose capital it was. The city was known as Rabat ʿAmmān, with Rabat meaning either “capital” or “king’s quarters.” 

After occupying the city during his reign over the Ptolemaic Kingdom (283-246 BCE), Ptolemy II Philadelphus humbly renamed the city after himself; Amman regained its older, and current, name thanks to the Rashidun Caliphate in the seventh century CE. By the time Philadelphia, Pennsylvania, was founded in 1682, the name hadn’t been in use in Jordan for nearly 1,000 years. Today, there are also Philadelphias in Illinois, Indiana, Mississippi, Missouri, New York, and Tennessee, but only the one in Pennsylvania has Gritty.

‘Mitochondrial Eve’ is the common ancestor of all humans.

If you were to trace all our family trees as far into the past as possible, you’d find we’re all related — albeit extremely distantly. The common female ancestor from whom all humans are descended is Mitochondrial Eve, and scientists believe she lived in Africa some 200,000 years ago. Recent research may have narrowed down that location to an oasis in the Kalahari Desert, making it the “ancestral homeland of all humans alive today,” according to the researchers. Eve is technically known as Mitochondrial-Most Recent Common Ancestor, or mt-Eve and mt-MRCA for short, and her lesser-known male counterpart is known as Y-chromosomal Adam. He’s also believed to have lived in Africa, around 150,000 to 300,000 years ago.

The idea of a common ancestor has led to the misconception that Mitochondrial Eve was the first female human, which isn’t correct. Rather, she was the most recent common ancestor to whom every living person can trace their genealogy. Every human on the planet carries the Eve gene, including 147 people and fetuses from the original 1987 study. That study wasn’t the first to hypothesize a common ancestor, but the researchers behind it did coin the term Mitochondrial Eve.

It once rained meat in Kentucky.

March 3, 1876, was a cloudless day in Olympia Springs, Kentucky. Late that morning, a resident named Rebecca Crouch was out in her yard making soap when a strange kind of snow began to fall. At least, that’s how she described some of the pieces drifting down: about the size of snowflakes, only they weren’t white. They were red, and they looked like meat — beef, she thought. 

According to a New York Times report shortly afterward, “Mr. Harrison Gill, whose veracity is unquestionable … visited the locality the next day, and says he saw particles of meat sticking to the fences and scattered over the ground.” The paper also noted that “two gentlemen, who tasted the meat, express the opinion that it was either mutton or venison.”

The first scientific analysis came three months later, when a water treatment specialist named Leopold Brandeis examined specimens preserved in glycerine. He declared that “the Kentucky ‘wonder’ is no more or less than nostoc.” Nostoc — also known as star jelly or witch’s butter — is a type of cyanobacteria that swells into green, jellylike masses after a rain. But the theory had problems: The mystery material wasn’t green, and it hadn’t been raining, and it didn’t explain why it looked and tasted like meat. 

While the circumstances remain mysterious, the leading scientific theory today is that the Kentucky meat shower was the result of projectile vulture vomit. Vultures are common in Kentucky and are known to disgorge their stomach contents when spooked. 

Writing in an 1876 edition of the Louisville Medical News, chemist L.D. Kastenbine explained: “The only plausible theory explanatory of this anomalous shower appears to me to be … the disgorgement of some vultures that were sailing over the spot, and from their immense height, the particles were scattered by the then prevailing wind over the ground. The variety of tissue discovered — muscular, connective, fatty, structureless, etc. — can be explained only by this theory.”

Whatever really fell from the Kentucky sky that day, the event now sits firmly in the canon of classic weird facts. It’s been celebrated in books and podcasts, and even marked with a festival featuring a mystery meat chili cook-off.

The 3 Musketeers candy bar was named for its flavors.

The 1930s were a landmark time for the candy business. Despite the economic hardships of the Great Depression, confectionary companies flourished, launching popular products that still remain in demand today. Snickers, the top-selling candy bar in the U.S., debuted in 1930, and in 1932, another well-known sweet treat made its first appearance: the 3 Musketeers candy bar, or, more accurately, candy bars. At the time, each 5-cent package contained three bars with three different flavors: chocolate, strawberry, and vanilla. 

The three flavors resulted in the candy bar’s name, one that had already been made familiar by author Alexandre Dumas’ popular 1844 adventure novel The Three Musketeers. The 3 Musketeers bar remained a multipack from 1932 until 1945, but like many industries at the time, the candy business was majorly impacted by World War II. In 1942, government-mandated sugar rationing came into effect. When regular production resumed following the war in 1945, 3 Musketeers, citing ongoing challenges and costs related to wartime restrictions, was reduced to just one piece, available in just one flavor: chocolate. But despite the lower bar count, the name remained the same.

There have been copies of the Declaration of Independence for as long as there’s been a Declaration of Independence. The handwritten, signed document is currently safe from Nicolas Cage in the National Archives. But the Continental Congress’ printer John Dunlap made about 200 broadside copies of the document on July 4, 1776, of which 26 remain. These were posted in public places for soon-to-be Americans to read and celebrate. One of them will be sold at auction in May 2026 to commemorate the 250th anniversary of American independence, and it’s likely to fetch a high price — another was recently sold for $5.6 million.

In an interview with Philly Voice, Ken Goldin, founder and CEO of the auction house near Philadelphia that will be selling the rare document, described it as being in “tremendous condition” despite the fact that it “may have been posted in a tavern or some kind of hall.” More than 400 other historical objects also will be available at the auction, though Goldin has yet to reveal what they’ll be. The copy of the declaration will be lot No. 1, however, and is sure to be the most sought-after item.
