more piece of mind? (giggles) Now on to the video. You've probably heard the expression two heads are better than one. Well, what about 330 million heads? That's how many people use the American Social News
Aggregation web content rating and discussion website known as Reddit. When something mysterious hits
this network of communities, some of these users band together
and take on the challenge and sometimes those users
bring forth incredible results. (ethereal music) These are 10 mysteries
solved by redditors. (ethereal music) Number 10 is Nequam Sonitus. Back in 2013, a man got something
quite strange in the mail and he decided to post the
content immediately on Reddit. What he got was a CD with a
playlist and a police report. When he played the CD, he realized that one of the audio files contained hidden GPS coordinates which led to an abandoned
factory in Tampa, Florida. When redditors started commenting about what they knew of this property and speculating why it could
possibly be significant, a mysterious and creepy user account started responding to these comments. People lost their minds
over the whole thing and were determined to figure
out who is behind it and why. Eventually, they determined
that it was all viral marketing for the band Nequam Sonitus from Florida, a group of performance noise artists whose members remain unknown. (ethereal music) Number nine is ring thing. Pretty much any young person with an imagination for adventure dreams of exploring and finding
lost or buried treasures, but in the case of one Reddit user that thrilling dream became a reality. As a youth in the mid to late 1990s, they came across a golden ring in a grocery store parking lot. The piece of jewelry was
engraved with A, B and P 14K and F-L-P-R-M-C nine 1917 all
along the inside of the ring. After keeping the ring for about 20 years, they took to Reddit in hopes
that they could get help finally locating the
ring's rightful owner. Soon after posting, another user uncovered a marriage certificate
matching the engraving and the date on the ring. Further research revealed the initials stood for Frank Phillip
Listin and Ruby Marie Crisp who are both sadly deceased. (ethereal music) Number eight is Frame 3-9-4. A 28-year-old cinematographer
from Toronto, Ontario named Daniel Voshart
managed to entangle himself in one of America's most high profile police-involved mysteries. It all started in April of 2015 when the redditor first saw
shaky cellphone video footage of an unarmed man, Walter
Scott, falling to the ground after being taken down
by Officer Michael Slager who, moments later, apparently planted and then retrieved what
looked like a taser next to Scott's body. After weeks of watching this clip, he noticed something in the 394th frame that had him reaching out to
the FBI and ballistics experts. It was evidence that could've
potentially saved Slager from facing a life sentence. Voshart refused a retainment offer from the ex-officer's lawyer and the case eventually concluded without using Voshart
as an expert witness. (ethereal music) Number seven is an ear worm. Have you ever heard a
song you liked so much, you quickly pull out your
phone to figure out what it is? Well, what if that song is so obscure that even the internet doesn't know? This was the case with a
new wave song from the '80s that no one could identify. Dubbed "Stay" by fans, the song had been ruminating
on message boards and Reddit but stumped everyone for years. The song's origin was
muddied and lost in time. All that was known was
that it was recorded at a German radio station
between 1984 and 1986. Finally, a redditor named Stefan who worked for a Swedish radio show recognized the song revealing that it was by an
artist named Johan Lindell. The show interviewed Lindell
discovering that "Stay" was really called "Up on the Roof" and was from his 1985
album, "Ghost Rider". (ethereal music) Number six is A858. In 2011, a previously
unused reddit account began posting seemingly random
strings of numbers and text in a new subreddit that it created. To the casual eye,
there wasn't much to see as it shared the same unreadable set of numbers and letters as its moderator. But soon enough, redditors saw
those strings of characters and decided that it was a code and a dedicated group of users
began trying to crack it. The creator of A858 was aware
of the growing attention and began dropping hints, jokes
and words of encouragement. One post even featured an
encrypted image of Stonehenge referencing a comment
that had called the puzzle the Stonehenge of Reddit. Some believe A858 to be a piece of art using the digital world as its canvas. Though the codes have been solved, the reason for them still remains unknown. (ethereal music) Number five is alien abduction. In 2013, a Reddit user tramstopdan began to document his experience digging through a box
he found in the trash. Inside he found beautifully
hand-rendered illustrations of heavily four-headed creatures along with technical drawings
of UFOs, personal belongings and a handwritten note
about what was either an extraterrestrial invasion or some kind of government coverup. There were even some non-patented
drawings of train wheels and hand-drawn maps from the late 1930s. In 2014, another redditor tracked down 85-year-old Elmer Arbov who is the nephew of Daniel Christianson,
the guy behind the box. Arbov said that his
uncle was obsessed with the book of Ezekiel and felt a tremendous need to create based on his thoughts about it. Many agree that Christianson probably suffered from schizophrenia. (ethereal music) Number four is an extension cord enigma. We all need our privacy, somewhere that we are free
from the gaze of others in order to relax and feel at ease. But in April of 2013, one user realized his
privacy had been destroyed after an extension cord
in his own dorm room suddenly blew up. Upon taking it apart, he found that inside was a strange series of
small wires and a sim card. He posted pictures of it to a subreddit where one commenter provided a link to a device sold on Amazon that looked like what he had found. It turned out to be a surveillance device which allowed someone to secretly listen to any noise in the room. He contacted the bug's manufacturer asking for more information but they told him that
they'd need a warrant. While we now know what the device was, we still don't know
what it was doing there. Very creepy. (ethereal music) Number three is meathead asking for help. In 2013, reddit user
meathead posted an image of a broken headlight that came off a car that had been involved in a hit-and-run. He asked for any help that might lead to the possibility of
identifying the driver. It didn't seem like much to go on seeing as that it was just
a piece of a headlight, but 400 Reddit comments poured in and eventually, one Reddit user
left the following comment. That was a tough one. It took me a minute to figure it out. That light came off a
1990 Cadillac Brougham. That comment received hundreds
of upvotes almost instantly. So meathead took his new
information to the police and they were able to match
it to a stolen vehicle. Thanks to this lead, they not only recovered the stolen vehicle but were able to identify the thief who had almost committed the hit-and-run and pressed charges. (ethereal music) Number two is Cicada 3301 puzzle. Between 2012 and 2014, a
cryptic message began appearing once a year on message
boards across the internet. Claiming to seek highly
intelligent individuals, the Cicada 3301 puzzle challenged visitors to find a secret message
hidden in an image that accompanied it. Joel Ericson, a 34-year-old
crypto security researcher and redditor from Sweden was one of the few people
who actually solved it since the first challenge appeared online. To this day, nobody has publicly taken credit for these puzzles, but Cicada must be the work
of more than one person with some hefty resources at that. So far, physical artifacts from the group have appeared in eight
nations and 11 US states. It has bought phone numbers, paid for server uptime and offered something to the winners which has earned their silence. (ethereal music) And number one are carbon copies. In 2016, Reddit user bradbury1920 described finding mysterious post-it notes around their home with handwriting on them that they didn't recognize. The user had even set up a
webcam to solve the mystery but discovered that the
footage had been deleted and the computer's trash emptied. They found no other signs on a break-in but they were obviously disturbed
and asked Reddit for help. A fellow redditor commented
that it was possible that it was bradbury1920
who was writing the notes and forgetting about them, stating that headaches and memory loss were possible signs of
exposure to carbon monoxide. After reading this, bradbury1920 put up a
carbon monoxide detector and discovered dangerous
amounts of it in their home. They sought medical attention
and had the issue addressed and no more notes ever appeared. Thank you to everyone for
