Imagine standing at the entrance of a dark, mysterious cave, its passages twisting deep underground. While the thought of sliding into the unknown might spook most, for thrill-seekers, it’s just another day of exploration. The @ActionAdventureTwins, a duo of cave explorers on YouTube, captured this eerie experience by dropping a GoPro into one of the deepest pits in the US. The video, now a viral hit, has left many viewers with chills.

The video, posted by James and Edward, the @ActionAdventureTwins, has racked up 362,000 views and nearly a thousand comments. It also features guests Nate and Ben, identical twins from Pennsylvania who run their own adventure channel, @DeepFreedom.

“We took a GoPro down into the deepest pit in the U.S, and are the first people to drop it down to the bottom of this cave,” the team claimed in the caption but it should be noted that the cave has been explored and mapped by several speleologists for decades before this team. The spot in question here is the Fantastic Pit in Ellison’s Cave, located in Walker County on Pigeon Mountain in the Appalachian Plateaus of Northwest Georgia. It is the deepest unobstructed underground pit in the country at 586 feet. Ellison’s Cave is 12 miles long and 1,063 feet deep, making it the 12th deepest cave in the United States.

At the start of the footage, one of the twins explains, “We’re gonna rappel down like, 128 feet, and we’re gonna see the deepest cave in America, and we’re gonna drop a GoPro down it.” The duo stand at the rocky mouth of the pit, smeared with soil, tangled vines, thick bushes, and dried leaf mold.

The explorers drop the GoPro camera down the opening, sending it deep into the dark belly of the pit. The first drop is about 125 feet down. Then the GoPro is dropped down another pit with a depth of about 586 feet. The footage first depicts scenery of flying dust motes with the sounds of dripping water. The rope attached to the camera descends, cascading between the jagged rocky structures and craggy walls.

In a moment, the team sees a waterfall. “That’s cool,” they exclaim. As the camera goes deeper into the pit, the audio becomes muffled. The camera rotates in circular motion revealing the precipitous cave walls with monstrous accumulation of limestone formations and fractured gypsum rocks. The camera then flashes the bedrock of the cave mounded with stones and pebbles. At this time, the GoPro is 714 feet below the Earth’s surface.

Finally, they pull the rope upwards from the black abyss. While pulling it back, they almost seem to lose the camera as it gets entangled in the axle of the drill. One of the twins says at the end of the footage, “I don’t know what this footage looks like but I am just surprised we got the GoPro back.”

The footage of the shadowy chasm gave eerie vibes to several people. “I’m not going to lie, when it got to the bottom I was anxious for a second. I saw one of those white rocks and was like… omg is that a ghost,” commented @bombud1. @trilfiger448 added, “The muffled descending sound was terrifying! And the spinning…I was just waiting for something to jump-scare me.”

@waya420 said, “Honestly surprised, the bottom wasn’t full of water. It must drain out somewhere even deeper. It would be fun to explore it with a drone if you could.”

The footage was also shared on Instagram where it has 371k views and over 10k likes.

If this wasn’t enough scary an experience, the pair of cavers twins descended the pit a second time in November 2023, this time going all the way down themselves. They spent 12 hours inside this cave, and narrated their experience in the caption, “We can’t believe we finally managed to drop down the pit after planning this for a long time. We will be back to this cave to see where it goes down there!”

  • Italian man claims to be ‘human cheetah’ with lightning-fast reflexes
    Photo credit: CanvaA man with fast reflexes.

    At first glance, this probably looks like a camera trick. Ken Lee, an Italian content creator, has built a massive online following by doing something that doesn’t quite feel real. Viewers refer to him as the “human cheetah” because it appears he has near-instant reflexes.

    Grabbing objects out of the air with uncanny precision, flicking clothespins and lighters, and throwing a blur of punches and kicks at impossible speeds, it is easy to call him unbelievable. Half the audience thinks his viral speed videos are fake. The other half is just as convinced they are watching something incredibly rare.

    Hands so fast they blur time

    In the video above, a timer runs to confirm its authenticity. In what looks like half a second, he reaches out and snags the lighter from the table. To prove it is real, he does it twice.

    Having amassed millions of followers on his TikTok page, the identity behind the mysterious influencer remains largely unknown. Active since around 2022, with almost 100 million accumulated likes, Lee has cultivated a fandom around his self-proclaimed “Superhero per Hobby!”

    Do you believe it is real? Is this person the fastest human alive? Many followers cannot wait for the next video to be posted. Plenty of his fervent fans are Italian, so sifting through the remarks takes a bit of hunting. Here are some comments that sum up how much people enjoy the fun and the spectacle:

    “Ken lee the fastest and the best”

    “Most dangerous human”

    “Is this what the lighter sees before my homie steals it”

    “It was sped up during he grabbed the lighter, if u count up with the timer u would be off by like 0,5 seconds whenever he grabs the lighter.”

    “If the flash were human”

    “How is it possible to get such powers ?”

    “I blinked and I missed it”

    People love good entertainment

    The awe of peak performance attracts people to watch elite athletes, musicians, or even dancers. There is something that deeply satisfies all of us when a human appears to push a skill to its limit. Whether it is real or fake seems to matter less than the opportunity to chime in on some good entertainment.

    How far could any of us go by practicing and repeating a particular motion over and over until it is mastered? Beneath the flashy nickname and his viral speed videos, Lee’s content has a way of drawing people in. This is not a superpower. Just repetition. Focus. Obsession. And maybe some digital wizardry.

    Testing the science of speed

    If you wish to question the validity of Lee’s performances, maybe some basic science can help. Human reaction time is not just a reflex. A 2024 study found that the nervous system can fine-tune responses in real time. Practice can make movements appear almost automatic.

    It has been well established in research that the gap between seeing something and responding has a limit. A 2025 study concluded that the most elite extremes allow for reaction times of 100 milliseconds. At that speed, the human brain can barely process that something has happened.

    Science explains Lee is not necessarily moving as fast as we might perceive him to be. And therein lies all the fun of it. We cannot prove it is real, nor can we actually prove that it is fake.

    Maybe Lee is the “fastest man alive” or the so-called “human cheetah.” Or maybe he is just a remarkable entertainer. Either way, he has clearly tapped into something strange and fascinating: a blend of human ability and fantasy that people do not want to miss.

    To give context to Lee’s videos, watch this performance on Tú Sí Que Vales:

  • Despite all the likes, literallys and dropped g’s, English isn’t decaying before our eyes
    Photo credit: LisaStrachan/iStock via Getty Images Fear not: There isn’t anything that needs saving.

    As a linguistics professor, I’m often asked why English is decaying before our eyes, whether it’s “like” being used promiscuouslyt’s being dropped deleteriously or “literally” being deployed nonliterally.

    While these common gripes point to eccentric speech patterns, they don’t point to grammatical annihilation. English has weathered far worse.

    Let’s start with something we can all agree on: Old English, spoken from approximately A.D. 450 to 1100, is pretty unintelligible to us today. Anyone who’s had the pleasure of reading “Beowulf” in high school knows how different English back then used to sound. Word endings did a lot more grammatical work, and verbs followed more complicated patterns. Remnants of those rules fuel lingering debates today, such as when to use “whom” over “who,” and whether the past tense of “sneak” is “snuck” or “sneaked.”

    The language went on to experience centuries of tumult: Viking invasions, which introduced Old Norse influence; Anglo-Norman French rule, which shifted the language of the elite to French; and 18th-Century grammarians, who dictated norms with their elocution and grammar guides.

    In that time, English has lost almost all of the more complex linguistic trappings it was born with to become the language we know and – at least, sometimes – love today. And as I explain in my new book, “Why We Talk Funny: The Real Story Behind Our Accents,” it was all thanks to the way that language naturally evolves to meet the social needs of its speakers.

    From dropping the ‘l’ to dropping the ‘g’

    The things we tend to label as “bad” or sloppy English – for instance, the “g” that gets lost from our -ing endings or the deletion of a “t” when we say a word like “innernet” – actually reflect speech habits that are centuries old.

    Take, for example, “often.” Originally spoken with the “t,” that pronunciation gradually became less favored around the 15th century, alongside that “l” in “talk” and the “k” in know. Meanwhile, the “s” now stuck on the back of verbs like “does” and “makes” began as a dialectal variant that only became popular in 16th-century London. It gradually replaced “th” whenever third persons were involved, as in “The lady doth protest too much.”

    While dropping the “l” in talk may have been initially frowned upon, today it would be strange if you pronounced the letter. And the shift makes sense: It smoothed out some linguistic awkwardness for the sake of efficiency.

    If people learned to look at language more like linguists, they might come around to seeing that there is more than one perspective on what good speech consists of.

    And yes, that absolutely is a sentence ending with a preposition – something many modern grammar guides discourage, even though the idea only took hold after 18th-century grammarian Robert Lowth intimated it was a less elegant choice based on the model of Latin.

    Though Lowth voiced no hard and fast rule against it, many a grammar maven later misconstrued his advice as an admonition. Just like that, a mere suggestion became grammatical law.

    The rise of the grammar sticklers

    Many of today’s ideas about what constitutes correct English are based on a singular – often mistaken – 19th-century view of the forces that govern our language.

    In the late 18th century, the English-speaking world began experiencing class restructuring and higher literacy rates. As greater class mobility became possible, accent differences became class markers that separated new money from old money.

    Emulation of upper-crust speech norms became popular among the nouveau riche. With literacy also on the rise, grammarians and elocutionists raced to dictate the terms of “proper” English on and off the page, which led to the rise of usage guides and dictionaries that were eager to sell a certain brand of speech.

    Another example of grammarian angst reconfiguring the view of an otherwise perfectly fine form is the droppin’ of the “g.” It became so tied to slovenly speech that it was branded with an apostrophe in the 19th century to make sure no one missed its lackadaisical and nonstandard nature.

    Up until the 19th century, however, no one seemed to care whether one pronounced it as “-in” or “-ing.”

    Evidence suggests that -ing wasn’t even heard as the correct form. Many elocution guides from the 18th century provide rhyming word pairs like “herring/heron,” “coughing/coffin” and “jerking/jerkin,” which suggest that “-in” may have been the preferred pronunciation of words ending with “-ing.” Even writer and satirist Jonathan Swift – a frequent lobbyist for “proper” English – rhymes “brewing” with “ruin” in his 1731 poem “Verses on the Death of Dr. Swift, D.S.P.D..”

    Embrace the change

    Language has always shifted and evolved. People often bristle at changes from what they’ve known to what is new. And maybe that’s because this process often begins with speakers that society usually looks less favorably on: the young, the female, the poor, the nonwhite.

    But it’s important to remember that being disliked and bad are not the same thing – that today’s speech pariahs are driven by the same linguistic and social needs as the Londoners who started going with “does” instead of “doth” or dropped the “t” in often.

    So if you think the speech that comes from your lips is the “correct” version, think again. Thou, like every other English speaker, art literally the product of centuries of linguistic reinvention.

  • 10 boys and 10 girls were left alone in separate houses and the different results are just wild

    It sounds like the plot of William Golding’s Lord of the Flies. However, in the mid-2000s, it was a very real and very controversial reality television experiment.

    Footage from the UK Channel 4 documentary Boys and Girls Alone is captivating audiences all over again. It offers a fascinating and chaotic look at what happens when you remove parents from the equation.

    The premise was simple but high stakes. Twenty children, aged 11 and 12, were split into two groups by gender. Ten boys and ten girls were placed in separate houses and told to live without adult supervision for five days.

    The Setup

    While there were safety nets in place, the day-to-day living was entirely up to the kids. A camera crew was present but instructed not to intervene unless safety was at risk. The children could also ring a bell to speak to a nurse or psychiatrist.

    The houses were fully stocked with food, cleaning supplies, toys, and paints. Everything they needed to survive was there. They just had to figure out how to use it.

    The Boys: Instant Chaos

    In the boys’ house, the unraveling was almost immediate. The newfound freedom triggered a rapid descent into high-energy anarchy.

    They engaged in water pistol fights and threw cushions. In one memorable instance, a boy named Michael covered the carpet in sticky popcorn kernels just because he could.

    The destruction eventually escalated to the walls. The boys covered the house in writing, drawing, and paint. But the euphoria of freedom eventually crashed into the reality of consequences.

    “We never expected to be like this, but I’m really upset that we trashed it so badly,” one boy admitted in the footage. “We were trying to explore everything at once and got too carried away in ourselves.”

    Their attempts to clean up were frantic and largely ineffective. Nutrition also took a hit. Despite having completed a cooking course, the boys survived mostly on cereal, sugar, and the occasional frozen pizza. By the end of the week, the house was trashed, and the group had fractured into opposing factions.

    The Girls: Organized Society

    The girls’ house looked like a different planet.

    In stark contrast to the mayhem next door, the girls immediately established a functioning society. They organized a cooking roster, with a girl named Sherry preparing their first meal. They baked cakes. They put on a fashion show. They even drew up a scrupulous chores list to ensure the house stayed livable.

    While their stay wasn’t devoid of interpersonal drama, the experiment highlighted a fascinating divergence in socialization. Left to their own devices, the girls prioritized community and maintenance. The boys tested the absolute limits of their environment until it broke.

    The documentary was controversial when it aired, with critics questioning the ethics of placing children in unsupervised situations for entertainment. But what made it so enduring, and why footage keeps resurfacing years later, is what it reveals about how kids are socialized long before anyone puts them in a house together. The boys weren’t born anarchists and the girls weren’t born organizers. They arrived at those houses already shaped by years of being told, implicitly and explicitly, what boys do and what girls do. Whether that’s a nature story or a nurture story is the question the documentary keeps asking without quite answering, which is probably why people are still watching and arguing about it nearly two decades later.
