Will-o’-the-Wisps and 5 Other Mysteries Science Can Explain

Thanks to Skillshare for sponsoring this episode
— and this whole week! — of SciShow. [ INTRO ] To the frustration of scientists everywhere,
things in this world sometimes just don’t make any sense. But for the rest of us, that can be kind of
amazing. Imagining what could cause unexplained phenomena — like weird lights in the sky, or sightings
of mythical creatures — can be a lot of fun. Just ask half the forums on the Internet. But it’s also good to remember that the
world doesn’t have to be shrouded in mystery for it to be fascinating. Exploration can be just as cool as speculation. So to that end, here are six mysteries — from the Easter Island statues to will-o’-the-wisps
— that scientists have managed to solve. We’ve talked about all kinds of weird weather
here on SciShow, but this might be one of the best and most
horrifying stories yet. Imagine it’s March 1876, and you’re living
in Bath County, Kentucky. You’re outside on a beautiful, perfectly
clear spring day when the unthinkable happens: It starts to rain chunks of meat. Some of them are small — about 5 by 5 centimeters
— but others are as big as your hand. And soon, your yard is covered in the stuff. I wish I could say this wasn’t a true story,
but yeah, this 19th-century version of “Cloudy with a Chance of Meatballs” actually happened. According to the New York Times, two guys
even tasted the meat rain — because they just had to be curious — and
decided it was either mutton or venison. This event came to be called the Kentucky
Meat Shower, and it baffled people for decades. Originally, one person thought the culprit
was something called nostoc — which we now know is a kind of bacteria covered
in a jelly-like membrane. And when it rains, that membrane swells up. Except, it wasn’t raining when the meat
shower happened, so that idea was tossed out the window. Eventually, though, scientists did figure
it out after studying some preserved samples. They found that the meat was meat — specifically, a mixture of animal lung tissue,
muscle, and cartilage. And later in 1876, the chemistry professor
L.D. Kastenbine discovered where it came from: synchronized, projectile vomiting vultures. This story is amazing. There are two species of vulture native of
Kentucky, and their eating habits totally explained the shower. For one, vultures aren’t picky eaters, which
is why there were various kinds of tissue, and why the meat pieces were all different
sizes. But more importantly, vultures are also frequent
vomiters. Vultures are known to eat huge meals, and if they’re disturbed before they have
time to digest all that food, they sometimes throw it up to make themselves lighter and
make escape easier. So Kastenbine concluded that, on that day
in Kentucky, a group of vultures just happened to be flying
overhead, and all puked at the same time. It’s possible that this has even happened
in other places, too, but cases haven’t been well-documented. Either way, yeah, it’s a little gross. But it’s the Kentucky Meat Shower, there
was never going to be a not gross explanation Easter Island in the southeast Pacific is
famous for its giant statues. They’re called moai, and they were built
at least 400 years ago by the Rapa Nui people of Polynesia. But here’s a lesser-known fact: Those statues
used to have little, reddish hats. Okay, maybe “little” is an understatement. The hats were about two meters across and
weighed up to 12 metric tons. And until 2018, it was pretty unclear how
the Rapa Nui managed to put them on the statues. After all, the moai are some 10 meters tall,
and the hats were really heavy. Also, it was hundreds of years ago. Cranes were a little on the scarce side. But using modeling, a team finally figured
it out. In a 2018 paper published in the Journal of
Archeological Science, researchers discovered that the Rapa Nui likely
used a technique called parbuckling. First, they would have carved the stones into
cylinders. This red rock is actually found on the other
side of Easter Island, so making a cylinder out of it allowed them
to roll it over to where the moai were. Then, they built a ramp leading up to a statue’s
head. They tied a rope around the cylinder, and then a team of probably 15 people hauled
it up the ramp and put it on top of the statue. After that, the hat was carved into its final
shape. It sounds like figuring that out would have
been easy, since it’s all based on simple machines
you might have learned about in elementary school. But discovering this required building 3D
models of about 50 statues and 13 cylinders, as well as making all kinds of calculations
about the weight of the rocks and the strength of the average ancient Polynesian. Today, you probably won’t see many of these
hats still on their moai, since weather and erosion have knocked most
of them off. But at least they’re no longer a mystery. Scientists can’t tell us how to predict
an earthquake, since there are so many variables to keep track of. But they can tell why before and during ‘quakes,
people have sometimes reported seeing mysterious lights in the sky. They’re called earthquake lights, and they
can take all kinds of forms, from blue flames to lightning that shoots
out of the ground. People have recorded seeing them as far back
as the 1600s, and they’ve been observed up to weeks before
major earthquakes and up to 160 kilometers from the epicenter. Unsurprisingly, some people blamed these lights
on UFOs. Others thought they were caused by disruptions
in the Earth’s magnetic field. But the real answer came in 2014, in a paper
published in Seismological Research Letters. In it, the authors investigated data from
65 earthquakes where people had reported seeing lights. And they found that, most likely, the culprit
was electrical activity in certain types of rocks, especially volcanic ones. The team discovered that, when you put a lot
of stress on these rocks, they can release electric charge. The pressure causes the chemical bonds between
certain compounds in the rocks to break, which releases charged oxygen atoms. If enough bonds are broken at once — like before or during a big earthquake
— a bunch of those charged atoms can rush up
to the surface, usually at a fault, where two sheets of rock meet. Then, when they burst above-ground, they can
ionize the air, giving /air molecules/ electric charge. And that ultimately creates the various flashes
of light. The conditions that cause these are pretty
specific, which explains why earthquake lights are only
seen in about 0.5% of earthquakes. And the team also mentioned that this phenomenon
can explain other things detected before quakes, like low-frequency radio emissions. Unfortunately, understanding earthquake lights
probably won’t help us predict ‘quakes, since they’re so rare and since people usually
don’t report them. But hey… take that, UFOs! With average summer temperatures around 45°C,
California’s Death Valley probably isn’t a place you’d want to sit for very long
— unless you’re trying to solve the mystery
of the Sailing Stones. These are rocks that sit in one of the valley’s
dry lake beds, called the Racetrack. They can weigh up to 320 kilograms, and they seem to move… by themselves. Of course, they don’t move very much. Some can sit in the same spot for decades. But they usually leave long streaks behind
them as they travel, and that shows us that some of these rocks
have moved more than 450 meters. For years, people couldn’t figure out what
was going on. Explanations ranged from hurricane-force winds
to films of algae. And to make matters worse, no one had actually
seen a rock move. That is, until a few years ago. In 2011, a team of researchers tried to solve
the mystery of the Sailing Stones by sticking GPS sensors on them and then… just kind of waiting for something to happen. Since the rocks move so infrequently, one
of the paper’s authors expected this to be, quote, “the most boring experiment ever”. Two years into the project, a couple of the
scientists showed up at the Racetrack to make observations, only to discover the lake bed covered in a
thin layer of water. And then, to their amazement… they saw some
of the rocks move. They eventually published their paper — and
the solution to the mystery — in PLOS One. According to the team, the Sailing Stones
only move under specific circumstances. First, the Racetrack has to fill with water,
deep enough to form floating sheets of ice, but shallow enough not to cover the Stones. At night, the surface of the water has to
freeze. Then, in the morning, the ice has to break
up into floating panels. Under the right conditions, the wind will
push those panels of ice across the surface of the water, and the ice will push the Sailing Stones. It sounds impossible, but it makes more sense
if you realize that the Stones aren’t sailing very fast. At most, they move 2 to 6 meters per minute
— which you might not notice if you weren’t
looking closely. But over the years, that can add up, creating
those famous, long tracks across the ground. There is one more mystery that remains, though: Researchers aren’t positive this method
also applies to the biggest rocks in Death Valley. So there’s still one more thing to be solved. With so much of the ocean being unexplored,
it makes sense that there’s a lot we don’t understand about it. And whenever we discover something we can’t
explain, people are pretty quick to get out their sea
monster T-shirts. That’s what happened when we heard the Bloop
in 1997. Yes, that is the official term. Because it sounds like… well, a bloop. The sound was recorded off the coast of South
America, while researchers were looking for underwater
volcanoes, and it was really loud. It was captured by microphones more than 4800
kilometers apart, making it way too big for something like a ship or a whale. It also didn’t help that NOAA at one point
announced that the sound was, quote, “possibly biological.” But in 2005, nearly a decade later, scientists
found that it definitely wasn’t. As they recorded more sounds in the ocean,
especially ones near Antarctica, they concluded that the Bloop was probably
an icequake. That’s where a huge chunk of ice cracks
off a glacier. It makes a ton of noise, and audio recordings taken over several years
show that they sound just like the Bloop. No sea monsters required. Finally, will-o’-the-wisps. You can find stories about them — or something
similar — in folklore from around the world, and you
may have even seen them yourself if you spend a lot of time in marshes or swamps. Hey, I don’t know your hobbies. They’re blue-ish lights that drift over these
kinds of landscapes, and if you get too close to one — like Merida
in Brave — it will disappear. According to many legends, they’re some kind
of spirit or creature out to mislead curious travelers. But in reality, the explanation for these
lights… well, actually, it’s almost as strange. Because will-o’-the-wisps are probably caused
by spontaneous combustion. Not spontaneous human combustion, though — that almost definitely isn’t a thing. Just the regular kind, where something bursts
into flame without an obvious source. In this case, the lights are likely caused
by certain mixtures of gas reacting with atmospheric oxygen. These mixtures consist of things like methane,
carbon dioxide, and, most notably, compounds containing phosphine
— like one called diphosphane, which is known
to ignite in the presence of oxygen. Various studies have shown that these gases
can be produced in marshes, swamps, and cemeteries, likely by bacteria living in the soil and
breaking down organic matter. And when bubbles of that gas make it up to
the surface, poof — you have a will-o’-the-wisp. It is worth noting that there are other hypotheses
suggesting these lights might not be actual fires, but just clouds of glowing gas. An experiment published in 1980, for example,
showed that you get a sort of glowing green cloud if you mix crude phosphine and methane. But either way, the general mechanism of “swamp
gas + air” does seem to explain what’s going on. Since these reactions are pretty short-lived, it even explains why these lights seem to
disappear if you approach them. Also, researchers have pointed out that some
phosphine derivatives are super toxic. So if dangerous gas clouds kept popping up
in local swamps, that might have made people especially eager
to stay away. Everybody loves a good mystery, but the stories about how we solve mysteries
are pretty fascinating, too. After all, it takes a lot of curiosity and
wonder to become a professional scientist and say “You know what I want to study? The Bloop. Or will-o’-the-wisps.” Thanks for being curious, scientists. For centuries, people have been telling amazing
stories about phenomena like this. And even though scientists can explain how
some of them happen, that doesn’t make the stories themselves any
less worthwhile. Which is why I’m glad that Skillshare has
so many classes on storytelling. Skillshare is actually sponsoring this whole
week’s worth of videos, so every day this week, we’ll be highlighting
one of their more than 20,000 classes. They’re seriously a great way to learn new
skills, brush up on techniques, or discover totally new hobbies. Like, there’s one class called called Storytelling
101 that teaches you everything you need to know about storytelling, whether you write about science or
the supernatural. It’s by the author Daniel José Older, and
besides teaching you some major themes, he also gives you prompts, tips, and follow-up
classes to check out. Skillshare also has thousands of other classes
on things like art, music, cooking, and tech. And right now, they’re offering SciShow viewers
two months of unlimited access to every class for free! So, like, I know what I’m doing for the rest
of the day. If you want to join me, you can follow the

    Idk, they odds of that many vultures simutaniously puking sounds pretty far fetched in my opinion. Plus, don't you think at least one person would notice at least one of the vultures in the sky? I mean it's not impossible, but I feel it's more likely maybe a tornado happened somewhere relatively close, close enough not to effect kentucky, but also throw meat at them. It sounds more likely than a giant group of vultures puking all at ones

    Having personally seen a so-called Ball Lightning and also ionized air, I'm not convinced.

    Ionized air, which is a plasma, looks like lightning–it is forked, blue, and lasts momentarily. It raises vertically, if at all, because it is lighter than the rest of the atmosphere.

    Instances of ball lightning looks like … a ball. It doesn't actually look like lighting much at all. They are white, which suggests that if they are a natural phenomena, their temperature is between 4,000K~6,000K, below the energy level at which natural plasma is expected to manifest. They travel horizontally relative to the Earth, a trajectory that is impossible to replicate with conventional magnetic means. (Otherwise, we'd use magnets on airplanes.)

    The ""paper"" that was published was not about a scientific discovery. It was PURELY SPECULATIVE hypothesis, as stated in the paper. Furthermore, the paper did NOT find correlation between Earth Quakes and reports of ball lightning. Instead, it suggested that there might be an undetected set of faults around the regions near ball lightning reports, and concluded that this was not evidence which was found. What was found, is a statistical >> CORRELATION << between a very specific type of fault, and this the important thing: NOT EARTHQUAKE EVENTS, but just the angle of the ground ""near"" that location. I quote:

    "We don’t know quite yet why more earthquake light events are related to rift environments than other types of faults"

    – Dr. Thériault

    And what do know about that saying when statistical ""scientists"" claim to find a correlation?

    Based on my own personal experience, and also the information in the paper about EQL–which by the way, isn't cited at all in this video–I'm sticking with "unidentified flying object" for now.

    tl ; dr this is clearly another instance of p-hacking to get click-bait views, this (part of the) video bad, and Hank, you should feel bad. =/

    I'm thinking either the Easter Island Moai Hat explanation is incomplete or wrong. At a minimum I'm going to need some more graphical representation of how they "simply" Pull the hat up with a rope as an explanation. How did they wind up the rope around the hat, how once they got it to the top did they lay it on it's side into place? Did they have platforms on either side of the top of the head? How did they support they weight, and once they laid it flat, how did they slide it horizontally? I'm not saying it's wrong, I'm just saying this explanation was extremely brief and full of gaps.

    I have a question about will-o-wisps. Have will-o-wisps and fox fire been known to be the same thing? I’ve heard stories since I was a child about how will-o-wisps, little balls of light, appear in the moor and how people would chase them, often to fall in a moss pit or something. I also watched a Documentary of strange events with one high above the Appalachian mountains where I do not think there is gas. I’ve also heard of fox fire, balls of fire lit from bogs and swamps. So is fox fire and will-o-wisps the same thing. I would like to know as it’s a part of my culture on my fathers side and I can’t figure it out because the names are either confused or associate with a certain type of fungi. I hope you answer my question. If not that is ok.

    Do you hear yourself, a small army of vultures with their bellies full synchronistically vomiting at the same time while flying really slowly over just one spot, it's like saying UFO's are nothing but swamp gas, don't you know that vulture's can't actually fly on a full stomach after gorging themselves, which is what had to had happened for them to vomit the excess food in the first place, there are only two species of vultures in Kentucky, their wingspans are from 1.5 meters to 1.83 meters, not exactly small are they, I think the people of Kentucky would have noticed the army of fat vultures it would have taken to constantly "rain" down meat vomit over their heads, people notice when they get crapped on by a small bird, now imagine a dozen vultures crapping on your head, the vulture explanation is just not logical, it's BS & if you had any intelligence you would know it too.

    Will of the Wisp I have seen and they last longer than what you would expect from burning gas of some kind. They don't exhibit a true "flame" but rather a relatively faint glow and disappear withing a couple of seconds if the air around them is disturbed or is made to move by wind. The place I saw them was over swampland in Minnesota. I used to own 120 acres adjacent to a river and there was about 30 acres of swamp that was "ripe" at times and I could easily smell the gases when they were released into the air. At night you could occasionally see the Wisps, very aptly named, slowly drift around. I took photographs, some with long exposures, but they never did justice to what could be seen with the eye. I didn't have the right camera and the right film to do the job, but never felt I needed to since I figured it was probably just swamp gas glowing since I could smell it often.

    I didn't know will-of-the-wisps was considered a mystery. About ten years ago (if not more) I was reading a book about a boy who lived in a graveyard, and he always seeing those, so I asked my mom what those were and she casually explained then to me… So I clicked in the video to know what the heck were this will-of-the-wisps, since I know them with the name we use for them in Brazil (fógus-fatuos) and I have never heard their name in English before, and I tough it was a really funny name for a science mystery, and got quite disappointed on that one.
    In the other hand I have always tough that the meat shower was a urban legend, and it was the most bizarre thing ever, so the video was worth it!

    Having neuroscience as a major makes me really appreciate science, but I also think its important to have a healthy amount of open mindedness.

    We shouldn’t be so arrogant to think science is flawless, and I think any method that’s created by humans is intrinsically imperfect. In the ideal world, I think we can bridge science with spirituality.

    @4:10 except they litterally have half finished moai that prove the moai are nearly completely carved in the quarry before being transported anywhere.

    Things like the Maoi make modern religious behavior look like the laziest stuff ever. Oh, you lifted the Torah over your head? The Rapanui carved giant people, walked them across the island, and rolled giant rock hats to them and up a giant ramp. Step up your effort

    My guess on the explanation of the meat shower would of been some guy a few miles away decided to blow up a pile of dead sheep. The vulture thing is still a bit far fetched if you ask me.

    For a video made in 2019, this SciShow script is grossly outdated. By 2012 it was well known that the "hats" aka pukao were actually cut as part of the original moai. The people doing the work were brilliant engineers in physics, for people working with stone-age tools, and cut the pukao so it was already perforated (ie ready to be knocked off) in the first place. The new mystery became "why did they remove the pukao from some but not all of the moai?"

    If the meat shower was caused by vultures, it must have been more vultures that are in the entire United States. it sounds like they described their lawns and what not being completely covered with me and if you figure like an average vulture can eat maybe what 3 lb of meat that's not enough unless you had tens of thousands of vultures all puking it one time to make that happen. I'm calling 🐂💩 on the vultures even though this is a great video.

    In all honesty, most of these are theories. The easter island heads just as easily could have been buried in dirt to place the hat, then have the dirt removed.
    The sailing stones was amazing however! I always wondered if we'd find this out.

    Why would that be called spontaneous combustion though? It’s not spontaneous, it’s a specific set of conditions that would most likely always lead to the same result. If bacteria releases the gas and the gas reacts to the oxygen, it seems as non-spontaneous as striking a match 🤷🏻‍♀️
