    92 Things I Learned In April That Blew My Mind In Ways I Didn't Know Possible

    A muscle you might've been born without, an infamous serial killer meeting a First Lady of the United States, a species of frog that looks like poop, and much more!

    Before you continue reading, I want you to know that this post *might* contain a bunch of facts you've already read.

    Some context: I write a weekly series, published on Saturday mornings, where I round up a bunch of cool facts I learned that week. Then, at the end of every month, I take everything I learned and put it all into one convenient place for your reading pleasure ‚ÄĒ and that's what you're reading now. Here's the one I wrote in March.

    SO, without further ado, here are 92 Things I Learned In April‚ĄĘÔłŹ:

    Oh, and a quick warning: Number 11 on this list features a photo that people with trypophobia and arachnophobia might find disturbing.

    1. H.H. Holmes has been labeled America's first serial killer. Holmes's hotel, which has been informally referred to as his "Murder Castle," was in operation during the 1893 World's Fair in Chicago, which drew 27 million visitors, many of whom were out-of-towners looking for a cheap place to stay. For this reason, it's difficult to determine precisely how many people might've perished within the Murder Castle's walls:

    2. This is the hat worn by Abraham Lincoln to Ford's Theatre on the night he was shot on April 14, 1865. The silk band was added to honor his son Willie, who died of typhoid in 1862 and whose death had a profound and devastating effect on the Lincolns:

    3. This 75-pound (34-kilogram) monster is the "Pearl of Puerto Princesa," the largest pearl ever discovered:

    Filipino fisherman got stuck on a rock and he decided to bring it home as a good luck charm. And then he kept it under his bed for 10 years until one day his house burned down. Then he found out this "rock" was actually the biggest pearl ever found and is valued at $100.000.000. from interestingasfuck

    4. One of the most legendary pranks in the history of April Fools' Day was played by a man named Oliver Bickar, affectionally known as "Porky," who managed to convince the city of Sitka, Alaska, that this dormant volcano was about to erupt:

    April 1, 74. Oliver Bickar ignited 100 old tires in a crater, convincing nearby residents of Sitka, Alaska that the volcano was erupting. Round the rim of the volcano someone had spraypainted "April Fool" in 50 ft letters. He had been planning the prank for four years. from RedditDayOf

    5. LANSA Flight 508¬†was flying over the Amazon rainforest on Christmas Eve in 1971 when it was struck by lightning and destroyed instantly. Of the 92 people on board, only¬†Juliane Koepcke¬†survived. In an interview with BBC she recalled, "Suddenly the noise stopped and I was outside the plane. I was in a freefall, strapped to my seat bench and hanging head-over-heels. The whispering of the wind was the only noise I could hear." Aside from a broken collarbone, a torn ligament, and some cuts and bruises, she escaped the crash ‚ÄĒ and fall ‚ÄĒ without any major injuries...and then went on to survive in the wilderness for 10 days:

    17 year-old Juliane Koepcke was sucked out of an airplane in 1971 after it was struck by a bolt of lightning. She fell 2 miles to the ground, strapped to her seat and survived after she endured 10 days in the Amazon Jungle. from Damnthatsinteresting

    6. This is what the Burning Man festival looks like from above:

    Burning Man is cosmically beautiful. from Damnthatsinteresting

    7. When someone from the Northern Hemisphere visits the Southern Hemisphere ‚ÄĒ and vice versa ‚ÄĒ they might notice that¬†the moon appears to be upside down. Turns out, it's not just their imagination, as illustrated by this helpful diagram:

    People in Australia see moon upside down from Damnthatsinteresting

    8. It's not at all uncommon for giraffes (and other herbivores) to chew on bones they find lying around their environment. In fact, it's their primary source of calcium and phosphorous:

    Giraffe eating a skull- osteophagy is the practice in which animals, usually herbivores, consume bones. from natureismetal

    9. Located in Utah, Pando is considered by some to be the largest living organism on the planet. It occupies 106 acres, consists of over 40,000 individual "trees," and is believed to weigh about 13 million pounds (5,896,701 kilograms):

    10. Lieutenant Hiroo Onoda was a Japanese soldier who was stationed at a remote outpost in the Philippines during WWII and who remained there until 1974 under the belief that the war was ongoing. He and a few men (the last of which would die in 1972, leaving Lt. Onoda alone) remained on high alert for all those years, hiding from search parties and even killing locals who they believed posed a threat:

    11. In order to grow, tarantulas engage in a process called molting, during which they shed their old exoskeletons. This is what they leave behind:

    15. This massive 2010 traffic jam on the north-south Beijing-Tibet expressway stretched for 74.5 miles and lasted for 11 days. It was caused, in part, by road work:

    The China Highway 110 Traffic Jam lasted more than 10 days. Most cars moved at an estimated pace of 1 km per DAY from ThatsInsane

    16. This is the unbroken seal of the third inner shrine of King Tut's tomb. It was notable because, over the centuries, most tombs were raided by grave robbers and stripped of all their riches. Tutankhamun's tomb was relatively untouched because it was unintentionally buried during the creation of Ramesses VI's tomb, and it remained hidden until Howard Carter rediscovered it in 1922:

    The seal securing the entrance to the tomb of king Tutankhamun. When this photo was taken in 1923 the seal had remained intact for more than 3200 years [1600x1200] from ArtefactPorn

    17. This is the Centennial Light, the longest-lasting lightbulb on earth. It burns 24 hours a day, 7 days a week in Firestation #6 in Livermore, California, which means it serves a purpose beyond just record-setting. Its longevity is allegedly due, in part, to the fact that it's never turned off, as the constant heating and cooling of the filament is what causes most bulbs to burn out:

    In 1901, an eternal light bulb was connected in California. It still hasn't gone out today, 120 years later. It is cited as strong evidence of how products are purposely made not to last in modern technology. from interestingasfuck

    18. Sultan Kösen is a 38-year-old farmer from Turkey and the world's tallest living person. Here is Sultan's hand holding an average can of Pepsi:

    19. You can still find pieces of the original Star Wars set, which is located in the Sahara Desert just outside the Tunisian city of Tataouine. Yes, George Lucas named the planet Tatooine after the city:

    20. Also known as the platypus frog, the gastric brooding frog was notable for converting its stomach into a womb as the eggs it swallowed would turn to tadpoles, which would ultimately grow into fully formed frogs. Eventually, after not eating for six weeks straight, it'd "vomit" its little bundles of joy into the world. Scientists have been attempting to bring the now-extinct species back through cloning:

    When breeding, Australian gastric-brooding frogs (Rheobatrachus) would stop producing gastric acid, swallow their eggs, and carry them in their stomachs past metamorphosis. Extinct since 1985. from Naturewasmetal

    21. This species of frog looks like poo:

    25. In 1972, a plane carrying a Uruguayan rugby team to a match in Chile crashed high up in the Andes mountains. Of the plane's 45 passengers and crew,¬†33 would survive the crash¬†but only 16 would make it off the mountain alive. They endured freezing cold temperatures and near-starvation for 72 straight days, and were forced to eat the bodies of those who had died in order to survive. In an¬†interview¬†with National Geographic, Dr.¬†Roberto¬†Canessa ‚ÄĒ one of the survivors who was 19 years old at the time ‚ÄĒ clarified, "Cannibalism is when you kill someone, so technically this is what is known as¬†anthropophagy." The group struggled with the decision over whether or not to eat their fallen friends but ultimately it wasn't a choice at all; they likely would've starved otherwise:

    26. The Perseverance rover is getting a lot of press these days, but the Curiosity rover is still working hard on Mars. In March, it captured some clouds drifting across the martian sky:

    28. At the height of the Civil War ‚ÄĒ and with nothing to lose, for he had no intention of being taken alive ‚ÄĒ¬†Robert Smalls¬†seized an opportunity to escape slavery by commandeering a Confederate ship that was armed for combat while its captain was away. To pull off this daring escape, he fooled not one but¬†twoConfederate checkpoints into believing he was the ship's captain by donning his wide-brimmed hat and mimicking his mannerisms. This act of bravery ‚ÄĒ and brilliance ‚ÄĒ earned him not only his freedom but also the freedom of 17 others (including 3 children). He would go on to become a state assemblyman and state senator in South Carolina, and serve in the US House of Representatives:

    Robert Smalls was born into slavery. In 1862 he freed himself, his crew, and their families during the American Civil War by commandeering a Confederate transport ship. He went on to become American politician, publisher, businessman, and naval pilot. from nextfuckinglevel

    32. The captain of the USS Johnston was a Cmdr. Ernest E. Evans, who bravely sacrificed the ship as well as his life and the lives of his crewmen by charging into enemy territory and drawing fire so that American landing forces could retake the Philippines. For this selfless act, Evans became the first Native American to win the Medal of Honor. Here's a photo of the captain and his crew:

    42. Gaius Caesar, better known by his nickname¬†Caligula¬†(which means "little boots"), was a Roman emperor whom many believed would be a merciful and moderate leader compared to some of the tyrants who ruled before him ‚ÄĒ and sources say he was precisely that for the first six months of his reign. But then, very suddenly, he became gravely ill and this¬†unknown illness¬†would change him forever in strange and consequential ways. He would go on to be remembered for his murderous cruelty and his god complex, and he was eventually assassinated after a mere five years as emperor. This sapphire ring is believed to have belonged to him:

    44. This volcanic eruption in Geldingadalir, Iceland, is expected to last for quite some time; in fact, two new fissures opened up this week, causing lava to ooze from the earth in three separate locations. Fortunately, these eruptions don't post a threat to Reykjavík, though it is drawing plenty of tourists:

It's not known exactly how they got there or how long they've been there ‚ÄĒ these pigs are not native to the Bahamas. One theory suggests a group of pigs may have survived a shipwreck and swam over. Whatever the case, they're living the good life now:

    61. Archduke Franz Ferdinand, whose assassination would change the course of history, actually survived an assassination attempt earlier that day when a bomb that was intended to kill him ended up exploding underneath the car directly behind his in the motorcade. Fate would intervene, however, when Archduke Ferdinand decided to take an unplanned detour to the hospital to visit those injured in the attack. On the way, his chauffeur accidentally made a wrong turn and came to a stop right in front of 19-year-old Gavrilo Princip, who shot and killed him, setting off World War I. Here's the coat the archduke was wearing that day, still covered in his blood:

She was hired by the British government to infiltrate Nazi-occupied France and assist in recruiting, training, and arming members of the French resistance. She would eventually be captured and brutally tortured by the Gestapo. Even as they¬†ripped out all of her toenails¬†she would repeat these words: "I have nothing to say." She never once revealed the whereabouts of her co-conspirators and comrades in arms, and was ultimately sent to¬†Ravensbr√ľck, a concentration camp for women. Despite it all, Odette¬†Hallowes survived the war. She died at the age of 82 in 1995:

She¬†reportedly¬†also signed the photo, "To John Gacy, best wishes, Rosalynn Carter." He was arrested a year later and convicted of murdering 33 young men and boys, though there's speculation that there may have been even more victims:

    72. This is what a bottle of Coca-Cola looked like back in 1894; and yes, it did actually contain cocaine. In fact, though cocaine was eventually removed from the formula, the Coca-Cola you drink today still contains coca leaves (the plant that's used to manufacture cocaine) but the cocaine part of it is of course left out. They refer to the ingredient as "Merchandise No. 5," which is supplied to them by the Stepan Company, the only company in the US that's licensed to import and process coca plants:

    Released in 1894, this is the first publicly sold bottle of Coca-Cola, which contained around 3.5 grams of cocaine from interestingasfuck

    73. Cryonics is the act of freezing the dead in the hopes that science will someday become advanced enough to resurrect them. In Scottsdale, Arizona, there's a place called Alcor Life Extension Foundation and they're the self-proclaimed "world leader in cryonics, cryonics research, and cryonics technology." According to their website, they currently have 181 "patients." One of them is baseball legend Ted Williams and a former employee accused Alcor of mishandling Williams's corpse and also preserving his decapitated head separately from the rest of his body:

    74. The purussaurus was a prehistoric crocodile that is believed to be the largest croc to ever live. They would reportedly grow as large as 41 feet long (12.5 meters) and weigh 8.4 tons. It's also believed they had a stronger bite than the tyrannosaurus rex, with a pressure of *seven tons*:

    75. Machu Picchu was abandoned by the Incans shortly after being conquered by the Spanish in the 16th century and for centuries after it lay hidden high in the mountains. It was finally rediscovered in 1911. Here's what it looked like in 1915 before excavations began versus what it looks like today:

    76. Earlier this week, the Ingenuity Helicopter became the first aircraft to fly on Mars. One of the reasons this is such a huge deal is because there was no guarantee it would work. Mars has 1/3 of Earth's gravity and a *very* thin atmosphere (helicopters need air to fly and there's not a lot of that on the Red Planet).

    77. Even so, NASA was confident they would succeed. So sure were they that Ingenuity would make history by being the first aircraft to fly on Mars that under its solar panel they fastened a small piece of fabric from one of the wings of the Wright brothers' historic plane, the Flyer, which flew the first controlled and sustained flight on Earth.

    79. This white stork with a Central African spear through its neck isn't a recreation; it's the real deal, and it's on display in a German museum. There was a time when no one really knew where birds went during the winter months and in 1822, this hapless stork survived being speared in Africa only to make the long journey back to Germany to get shot by a hunter:

    Until a few centuries ago, many European zoologists were perplexed about where migratory birds went during the winter. The mystery was solved in the early 1800s when a stork returned to Germany with a spear from Central Africa through its neck.

    80. The¬†588th Night Bomber Regiment was an all-woman bomber squadron that flew roughly¬†30,000 night raids against the Nazis during WWII. Since the planes they flew were extremely rudimentary ‚ÄĒ made of little more than wood and canvas, and therefore very flammable ‚ÄĒ they needed to rely on stealth if they were to succeed (and survive), so they took to shutting off their engines as they approached a target. The only warning that an attack was imminent was a faint "whooshing" sound in the night sky, so the Germans took to calling them "Nachthexen," which translates to "Night Witches," a name that the women of the 588th would come to embrace:

    81. Pangolins are very unique animals for¬†a variety of reasons. One of those reasons is that they're covered in scales ‚ÄĒ the only mammals to possess this added layer of protection. What's¬†really¬†surprising about them, and what would¬†really¬†make you do a double take if you ever saw one out in the wild, is that, like humans, they walk on two feet:

    82. Some American honey contains low levels of radioactivity left over from nuclear bomb tests conducted in the 1950s and 1960s. How did it end up in honey? Long story short, the bombs sent a radioactive element into the atmosphere, wind and rain sprinkled it across the United States, some plants absorbed it, and bees pollinated those plants. Researchers say the amounts are very small and therefore harmless, but that "they may have been much higher in the 1970s and 1980s."

In a¬†brief interview¬†with National Geographic, famed luxury shoe designer Manolo Blahnik was blown away by "how much this shoes resembles a modern shoe." He called it "astonishing." In case you're wondering ‚ÄĒ like I was ‚ÄĒ it's a woman's size 7:

    85. This is what can happen to your skin if you survive being struck by lightning. The man pictured below felt soreness in his arm before noticing the marks and the following day the skin began to blister. In an interview with ABC News, Dr. Mathew Avram explained, "The feathering marks are formed by the transmission of static electricity along the superficial blood vessels that nourish the skin":

    86. In an ancient quarry in Egypt lies¬†the Unfinished Obelisk. It's estimated to weigh about 1,168 tons and, had it been raised, would've stood 137 feet tall ‚ÄĒ the tallest obelisk to ever exist at the time:

    87. These are the Pyramids of Mero√ę, which were once part of a wealthy ancient city in the Kingdom of Kush in what is now Sudan. If you're wondering what happened to the tops of the pyramids, which were once beautifully ornate, they were literally blown up in 1834 by an Italian treasure hunter named Giuseppe Ferlini, who then looted them and sold the artifacts to museums in Munich and Berlin.

    90. 100,000-year-old fossilized neanderthal footprints were¬†recently discovered¬†in Spain. Researchers determined that they were left by a group of 36 individuals and that some of the prints were left by a young child who was ‚Äújumping irregularly as though dancing‚ÄĚ:

    91. And these fossilized footprints, which stretch for a mile and are the longest continuous set ever discovered, were left by a woman and a small child who were in a great hurry. For some stretches, the woman carried the child and at times the child walked on its own. Other prints in the area suggest she may have been trying to avoid saber-toothed tigers and that she likely crossed paths with a mammoth and a giant sloth:

    92. Horses played a¬†much-more critical role¬†in World War I than you might think. Many battles were fought on rough and unforgiving terrains, ranging from arid deserts to steep mountains. In addition to being used in battle, horses were responsible for hauling gear, pulling artillery, and transporting the wounded ‚ÄĒ all in the midst of explosions, tank and gunfire, and tear gas attacks. Some estimate that as many as¬†8 million¬†horses were killed during the Great War. Here's how some veterans paid tribute to their bravery and sacrifice:
