The 1950s and 60s saw a vast proliferation of educational films on a wide variety of purely interpersonal topics. The Baby Boomers were still quite young and thus it was necessary to inform them of how to interact with others as they grew up and explored American society.

Although some of these films seem a bit odd by modern standards, a few stand out as immediately useful. This one, for example, by filmmaker James Parris, helps people learn how to use that technological marvel that still causes confusion: the sidewalk.

What should you do if you are walking along the middle of a sidewalk and someone else is doing likewise, but approaching you? Do not knock them over. There's a better and safer way to use a sidewalk.

These procedures apply to other ambulatory locations, too, such as the aisles of grocery stores and even the hallways of a house. Watch and learn.

The odds of getting hit by a piece of space junk are smaller than the odds of winning the lottery, but they are not zero. You can reduce your odds of winning the lottery slightly by not buying a ticket, while space junk could hit anyone. We've learned that most debris that falls out of orbit burns up on re-entry, and most of the rest falls into the ocean. That still leaves a few unfortunate people who have to deal with the fallout, so to speak. Just last month, a piece of a pallet of batteries crashed through the roof of a Florida home. The falling debris was foreseen, but no one knew where it would end up.

It wasn't the first time that space junk fell on unsuspecting people and their property- it's been happening since 1969. Of course now there is a lot more junk up there. Read up on five cases of damage caused by stuff falling from space at Cracked.

In 1985, the British pop rock band Tears for Fears debuted their single "Everybody Wants to Rule the World," which soared to the top of the charts across much of the world. It made heavy use of synthesizers and other electronic instruments, unlike the lower tech of the bluegrass cover band named Greenwood Rye.

This quintet includes the quintessential bluegrass instruments of the banjo, mandolin, and the fiddle. An acoustic guitar and upright bass fill the gaps to provide very convincing covers of a-ha's "Take on Me", Paul Simon's "You Can Call Me Al", and Led Zeppelin's"Good Times Bad Times".

Archaeologists have found cannabis remains in a 2,500-year-old grave, with evidence indicating it was used at the funeral. And you thought "putting the 'fun' in funeral" was just a mortuary joke. But seriously, folks, researching the origins of cannabis is difficult because it's been deliberately cultivated for so long that any cannabis growing wild is feral instead of truly wild, and documenting historic samples is iffy because of its illegal status in many places. Scientists were having a hard time even charting out its taxonomy until gene sequencing came along. What we do know is that the plant developed its amazing chemicals to deter enemies, but the cannabis plant had no idea that humans would come along and find those chemicals so attractive.  

Yeah, this video from PBS Eons is posted a day early as far as the informal holiday known as 420 is concerned, but that leaves time for sharing. This video isn't nearly as long as it looks; the last two minutes are promotional.  

You have probably heard of Munchausen syndrome, a psychological condition in which a person is driven to spin fantastic tales about false symptoms and illnesses for attention. It is formally referred to as “factitious disorder imposed on self," or in the case of Munchausen by proxy, “factitious disorder imposed on another.” That's when a parent gains attention by insisting their child is sick when there is no illness present. The disorder was not named for the doctor who discovered it, but for a pop culture character from the 18th century.

Baron Munchausen as a character is legendary for telling tall tales about his military career, from traveling to the moon to riding a horse underwater to battling exotic beasts to riding a cannonball. His appearances over the centuries saw him change from a liar to a deluded old man reminiscent of Don Quixote. The original novel about him, Baron Munchausen’s Narrative of His Marvelous Travels and Campaigns in Russia, was published in 1785 and gave birth to a character featured in many stories and several films since then. But that original novel by Rudolf Erich Raspe only portrayed him as a teller of fantastic tales that no one believed. In reprints and translations, the story grew until Munchausen was a mentally ill buffoon.

However, there was a real Baron von Munchausen, whose name was Karl Friedrich Hieronymus, and he was not pleased at all for his name to be associated with such a character. Hieronymus was a storyteller, but not a liar, and he spent the rest of his life trying to find Raspe and suing anyone associated with the novel. Read the story of the real Baron von Munchausen at Smithsonian.

Passover begins on the evening of April 22 (Monday) and will run through sunset on April 30. No, it doesn't always coincide with Easter. As they do every year, the Jewish a cappella group Six13 has unveiled another pop music parody for the holiday. This year their nine voices bring us "Matza Mia! An ABBA Passover." They've put new lyrics to four classic songs from the Swedish vocal group ABBA: "Take a Chance on Me," "Dancing Queen," "Gimme! Gimme! Gimme! (A Man After Midnight),” and “Mamma Mia!” They've also posted a song sheet if you want to use the new lyrics at your Seder or school program.

See also: previous Jewish holiday songs from Six13. I don't think anything will ever beat "5784" for Rosh Hashanah.

The school buses that roam the streets today look an awful lot like the first conventional school buses that came out of an American standardization conference in 1939. They are big, boxy, and bright yellow. They aren't the same buses, but they've carried that iconic look for 85 years. There are reasons for this: we want people to recognize school buses for what they are, and if it ain't broke, don't fix it. Also, school buses are different from consumer automobiles in that there are no customers to please. People who buy cars want modern styling, convenience, and the latest gadgets, while school buses aren't for status or luxury. We just want to get the kids to school and back safely.

However, you might be surprised at how school buses have evolved on the safety front. The only thing you might really notice is the rise of cab-over-engine buses, which makes it easier for drivers to see children crossing in front. Even though the first big, boxy, bright buses were already safer than cars, we've had many safety innovations in school buses over the years. Those improvements are worth every penny. Read about the evolution -and the lack of it- in school buses at Jalopnik.  -via Boing Boing

Imagine a scenario in which the Milky Way galaxy is full of alien civilizations that are advanced enough to travel and communicate with each other, but they don't pay any attention to us here on Earth. That idea can be followed by all kinds of jokes about how human civilization isn't civilized, or otherwise deserving of company. But theoretically, there are other reasons we might not have been contacted by these advanced aliens. We might be honestly too far away to make the trip worth it. We may be relatively too young to understand them. They might know about us and have decided we have nothing useful to offer them. Or we may be among the "do not land here" list for other reasons. Yeah, some of those reasons are getting us closer to the old joke. It's easier to think that we are truly alone in the universe. This video from Kurzgesagt is really 10:15 long; the rest is an ad.

It's Barbiecue sauce! Get it?

The Mattel and Heinz companies have secretly developed a Barbie-themed sauce in honor of the doll's 65th anniversary "after a huge public demand." It's a vegan mayonnaise that is tainted with beetroot juice to match the official Barbie shade of pink (hex code #e0218a).

Fortunately, Heinz is only releasing its product in the UK and Spain, and the United States is thankfully outside of the blast radius. My condolences to the Europeans, though. The trauma begins today at Tesco stores in Britain.

Travertine is a type of limestone that has become quite popular for home decorating because of the interesting natural patterns in it. Redditor Kidipadeli75 went to see the new travertine tiles his parents installed in their bathroom. Kidipadeli75 is a dentist, and recognized one of the patterns as a mandible! When he posted the picture to reddit, he got responses from other dentists, forensic odontologists, and archaeologists who concurred that it was a jawbone cut at an odd angle, possibly human. The tile was sourced from Turkey, and is believed to be around 200,000 years old, so it might be Neanderthal. Since the image was posted, Kidipadeli75 has been in contact with a paleoanthropology team.

John Hawks explains how this can happen, and it's more likely than you might think. Fossils abound in travertine, although they are mostly from animals. The process of retrieving and cutting travertine is fairly automated, so it would be easy to miss an obvious fossil like this one. So how would you feel about having human remains in your bathroom tile? -via Digg

Young Cal Clifford has been obsessed with octopuses since he was two years old. By the time he was nine, his parents knew that it wasn't a passing fad and decided to get him a pet octopus. They procured Terrence, a two-spot octopus, and a 60-gallon tank. What they didn't know was that Terrance was a female who had already mated. Several months later, she laid eggs that produced 50 baby octopuses!

Cal's father, dentist Cameron Clifford, consulted Dr. Tim Tytle, a reptile expert who has two octopuses. They have separated all the surviving baby octopuses (half of them, a much better survival rate than in the wild) and are housing them at Tytle's duplex. Each have names, like Pearl, Seaoncé, Jay Sea, InverteBrett, Swim Shady, Squid Cudi, Bill Nye the Octopi, and Champ. The Cliffords, who now own 90% of the octopuses in Oklahoma, are looking for homes for the babies, but will not let them go to private families. Octopuses do not make good pets. Instead, they are reaching out to aquariums and research facilities.

Female octopuses normally die soon after laying eggs, but Terrence is still around five months later. Meanwhile, she and her offspring have gone viral with hundreds of thousands of people following the octopuses on TikTok. -via Metafilter

We all recall that memorable scene in the movie Happy Feet when all the young emperor penguins go to sea for the first time, driven by instinct. They are terrified, but eventually the first one jumps in, and lets the others know it's okay. Scientists have recorded this first plunge many times, but they also found evidence that some juvenile migrations don't just go to the sea -they go in by jumping off high glacial cliffs! When you feel you must go to the sea, you go, whether it's a gentle jump off some floating ice or a plunge down a 50-foot cliff. For the first time, this phenomena has been filmed, using drones, by cinematographer Bertie Gregory for National Geographic. This footage is part of the documentary series Secrets of the Penguins, which will premiere a year from now, on Earth Day in 2025. -via Nag on the Lake

An archaeological excavation of a Viking burial ground in Gotland, a Swedish island in the Baltic Sea, revealed three adult women who had a feature not seen in Viking graves- skulls that had been shaped to produce a long cranium. Elongated skulls are shaped by binding the head in infancy, when the bones are soft, and have been found in many places around the world, but not in Sweden, and not in other Viking settlements. Why did it happen to these three women?

Vikings were no strangers to body modification, and sometimes sharpened their teeth to look more intimidating. But these Viking women were outliers. DNA tests showed they were from the Baltic Sea area. Could they have been born during their parents' travel to the Black Sea, were skull deformation was common? The burial sites indicate that they were accepted in the Gotland culture, and the misshapened skulls could have even been seen as a status symbol. Read about the mystery of the Viking women with long heads at Atlas Obscura.

The literal translation of tegelwippen is "tile wiping." In this context, it means getting rid of tiles. See, most homes in Dutch cities have their yard covered with tiles to make a patio. This makes lawn care easy, as all you have to do is pull the occasional weed from between the tiles. But there's a new campaign, spearheaded by Remco Moen Marcar, to encourage people to remove the tiles and plant trees and other greenery, in order to cool the city, improve drainage, and combat climate change. And what better way to get people involved than a competition?

The competition called the NK Tegelwippen began about a month ago and will continue through October, to find which town in the Netherlands can remove the most tiles from their private land, calculated as tiles per thousand residents. Those who've already taken the plunge say they are enjoying the outdoors more with cool gardens under the shade of trees. So far, the leader of the contest is the town of Venlo, at 144 tiles per thousand, a total of 14,636 tiles whipped away. The sponsors of the contest arrange to collect and dispose of the tiles, which are being recycled into building material. Read how the tegelwippen is going at The Guardian. -via Metafilter

Al Condominio, a restaurant that opened last month in Verona, Italy, would like for its patrons to fully enjoy the social aspects of public dining. This requires putting away phones and, hopefully, talking to other human beings who are physically present.

The Guardian reports that to encourage socializing, the restaurant encourages patrons to lock their phones in boxes. Once seated at a table, the patron hands the box key to a waiter, who provides free wine. So far, about 90% of patrons participate in this program.

Patrons can also write reviews and leave them in their phone boxes as they exit. Patrons who write the most positive reviews will receive free meals the next time that they visit.
