See what researchers found when they tested a bottle of Fiji Water against a glass of tap water.

Is bottled water REALLY all that bad?

The Story of Bottled Waterwww.youtube.com

Here are six facts from the video above by The Story of Stuff Project that I'll definitely remember next time I'm tempted to buy bottled water.

1. Bottled water is more expensive than tap water (and not just a little).

via The Story of Stuff Project/YouTube

A Business Insider column noted that two-thirds of the bottled water sold in the United States is in individual 16.9-ounce bottles, which comes out to roughly $7.50 per gallon. That's about 2,000 times higher than the cost of a gallon of tap water.

And in an article in 20 Something Finance, G.E. Miller investigated the cost of bottled versus tap water for himself. He found that he could fill 4,787 20-ounce bottles with tap water for only $2.10! So if he paid $1 for a bottled water, he'd be paying 2,279 times the cost of tap.

2. Bottled water could potentially be of lower quality than tap water.

Fiji Water ran an ad campaign that was pretty disparaging about the city of Cleveland. Not a wise move. The city ordered a test of the snooty brand's water and found that Fiji Water contained levels of arsenic that weren't seen in the city's water supply.

How was that possible? Sarah Goodman of the New York Times explains:

" Bottled water manufacturers are not required to disclose as much information as municipal water utilities because of gaps in federal oversight authority. Bottom line: The Food and Drug Administration oversees bottled water, and U.S. EPA is in charge of tap water. FDA lacks the regulatory authority of EPA."

3. The amount of bottled water we buy every week in the U.S. alone could circle the globe five times!

via The Story of Stuff Project/YouTube

That sounded like it just had to be impossible, so we looked into it. Here's what our fact-checkers found:

"According to the video, ' People in the U.S. buy more than half a billion bottles of water every week.' National Geographic says for 2011, bottled water sales hit 9.1 billion gallons (roughly 34 billion liters).

A 'typical' water bottle is a half-liter, so that's about 68 billion bottles per year. Divided by 52 weeks would be a little over 1 billion bottles of water sold per week in the U.S. Because that's based on a smaller 'typical' bottle size, it seems reasonable that a half billion bottles a week could be accurate.

The Earth is about 131.5 million feet around, so yep, half a billion bottles of varying sizes strung end-to-end could circle the Earth five times."

4. Paying for bottled water makes us chumps.

via The Story of Stuff Project/YouTube

Beverage companies have turned bottled water into a multibillion-dollar industry through a concept known as manufactured demand. Bottled water advertisements used a combination of scare tactics (Tap water bad!) and seduction (From the purest mountain streams EVER!) to reel us in.

Well, we now know their claims about the superior quality of bottled water are mostly bogus. And research shows that anywhere from a quarter to 45% of all bottled water comes from the exact same place as your tap water (which, to reiterate, is so cheap it's almost free).

via The Story of Stuff Project/YouTube

5. Bottled water is FILTHY.

It takes oil — lots of it — to make plastic bottles. According to the video, the energy in the amount of oil it takes to make the plastic water bottles sold in the U.S. in one year could fuel a million cars. That's not even counting the oil it takes to ship bottled water around the world.

And once we've guzzled our bottled water, up to 80% of the empty bottles end up in landfills or noxious-gas-producing incinerators. The rest is either recycled or shipped to countries like India where poor people without environmental and labor protections have to deal with it.

On top of all that, the process of manufacturing plastic bottles is polluting public water supplies, which makes it easier for bottled water companies to sell us their expensive product.

6. There are 750 million people around the world who don't have access to clean water.

A child dies every minute from a waterborne disease. And for me, that's the core of what makes bottled water so evil.

The video wraps by comparing buying bottled water to smoking while pregnant. That may sound extreme, but after learning everything I just did about the bottled water industry, I can't disagree.

via The Story of Stuff Project/YouTube

If you're properly disgusted, here are a few ways you can help destroy the bottled water industry:

Don't buy bottled water. Get a reusable water bottle. The savings will add up.
Rally your schools, workplaces, and communities to ban bottled water.
Demand that your city, state, and federal governments invest in better water infrastructure.

Animals & Wildlife

Scientists just solved the chicken-and-egg debate, so what will we argue about now?

A billion-year-old discovery has officially cracked the ultimate evolutionary mystery.

Richard Symonds

This handsome gent just got some bad news.

In the ultimate mic-drop for chicken-or-egg debaters, Chromosphaera perkinsii, a billion-year-old unicellular organism, reveals that nature had "eggs" on the menu way before chickens (or any animals) arrived. But, though the mystery has been unscrambled, the discovery has cracked open an entirely new chapter in the story of life's origins.

Meet Chromosphaera perkinsii, a single-celled organism found in marine sediments off Hawaii that threw evolutionary biologists a curveball. This tiny protist, dating back more than a billion years, does something remarkable: it organizes itself into multicellular structures that look exactly like the earliest stages of animal embryos.

Nature’s OG egg

Researchers from the University of Geneva (UNIGE), led by Omaya Dudin, have spent years studying this humble organism, and the findings are nothing short of stunning. Unlike most single-celled creatures, C. perkinsii can coordinate cell division without growing larger. Instead, it creates colonies that resemble the first steps of animal embryonic development.

"Although C. perkinsii is a unicellular species, this behaviour shows that multicellular coordination and differentiation processes are already present in the species, well before the first animals appeared on Earth."
— Omaya Dudin

Even more mind-blowing? When scientists analyzed the genetic activity within these colonies, they found it eerily similar to what happens in the embryos of modern animals. The processes that allow embryos to grow from a single cell into a multicellular organism—a hallmark of animal life—were apparently hanging out in the evolutionary toolbox long before animals even existed.

via GIPHY

A billion years of practice

The study, published in Nature, even raises the possibility that multicellularity evolved multiple times in different lineages, meaning the transition from single-celled life to complex organisms could be less linear (and more chaotic) than previously believed.

"It’s fascinating, a species discovered very recently allows us to go back in time more than a billion years."
— Marine Olivetta

The research could also reignite debates about mysterious 600-million-year-old fossils that look like embryos. Are they early animals or ancient organisms like C. perkinsii? Either way, this tiny protist suggests that nature was testing out egg-like developmental strategies long before anything resembling a chicken—or even a jellyfish—arrived on the scene.

The egg’s ultimate win

For anyone still clinging to the chicken in this debate, it’s time to throw in the towel. The egg wins by a landslide. And while these ancient “eggs” might not have shells or yolks, they set the stage for the evolutionary leaps that eventually gave us the breakfast staple we know today.

Still not convinced? Neil deGrasse Tyson shares the evolutionary approach to the puzzle. He bluntly points out that the egg came first; it was just laid by a bird that was not a chicken.

@neildegrassetyson we've cracked the case over which came first, chicken or egg! 🐣 #scienceflex
♬ original sound - StarTalk

Discoveries like this remind us how much we still don’t know about the origins of life. If a billion-year-old protist can hold the key to one of our oldest questions, imagine what else nature has waiting for us in its archives. But one thing’s certain: we finally have our answer. The egg was here first, and it’s been waiting for us to catch up for over a billion years.

So, with that settled, we are now tasked with finding something else to argue about. Science has yet to weigh in on the tree in the woods. Perhaps that puzzle will be the next to fall.

Crows are shockingly smart. Here’s how to make friends with one in four steps.

All it takes is a little food and patience.

via Krari The Crow/YouTube

How to befriend a crow.

When it comes to keeping birds as pets, people usually think about parrots or canaries. Nobody ever considers having a crow. But research has shown that crows are incredibly clever, curious and self-aware.

They recognize the faces of people they like or don’t like and have the ability to use tools. Looking to experience the magic of crows yourself? A YouTube user named Kräri The Crow from Germany made a video on how you can befriend the crows in your neighborhood in four easy steps. All it takes is “some food and some patience."

1. Find a pair of crows

Crows tend to live in areas where there are humans so chances are there are crows in your neighborhood. The best place to start is to find a pair with a fixed territory that you see on a regular basis. That way you're cultivating a relationship with the same animal day after day and you can "slowly get to know each other."

2. Offer food

Crows will eat just about anything from insects to invertebrates to meat. They also enjoy nuts, worms and vegetables. If you offer the food in the same place at the same time of day you'll establish a routine.

3. Be mindful

When interacting with the crow, make sure they aren't anxious or display signs that they are prepared to fly away at any moment. Approach the birds with an open, nonpointed gaze so as to not cause alarm. Sit quietly while you wait for the bird to approach and avoid quick movements.

4. Let the birds come to you

This requires patience. The crow will be shy at first, but they know you better than you think. They will remember your face and your kindness. Give them a chance to observe you and earn your trust.

A the end of the video, Kräri The Crow reminds everyone that we should make friends with crows but they are supposed to live free in the skies and not be stuck in a cage.

The reason why humans started kissing each other is kinda gross but really interesting

Let's just say love has evolved.

via Canva/Photos

A couple ready to smack lips.

There are few more beautiful moments in life than a romantic kiss. But there are a lot of other reasons why humans kiss, too. There’s the kiss that a parent gives a child to show them love. There’s the kiss that friends give each other on the cheek and the kiss of death from a mob boss, signaling that a member of the family is going to die.

Kisses play an essential role in the social lives of humans, but where did this behavior come from? Previous theories suggest it’s a holdover from the instinctual sucking that humans do as babies to get milk. Some researchers believe it’s behavior that evolved from when mothers would chew their baby's food before feeding it to them mouth-to-mouth.

Others have suggested that it’s a way for humans to sniff one another for “social” inspection. It’s a way of finding out where that person has been, who they've been with and what they've been eating.

Why do humans kiss?

A new research paper by Dr. Adriano R. Lameira, an Associate Professor and UK Research & Innovation Future Leaders Fellow at the Department of Psychology, University of Warwick, UK, argues that it comes from primate grooming rituals. “The most likely and straightforward evolutionary explanation is that mouth-to-mouth kissing evolved from an earlier form of kissing involving the mouth and other body parts,” he writes.

— (@)

The disturbing part is that, according to Lameria, when we pucker up our lips and suck on someone else, it mimics a behavior we used to remove parasites from one another’s fur when we were apes.

Why do primates groom each other?

Grooming is a vital ritual in the world of primates. It consists of one ape picking through the fur of another and removing parasites, dead skin and debris. “Grooming helps to establish and maintain alliances, hierarchies, and group cohesion through social touch, with the consequent release of endorphins, which reduces stress and promotes feelings of well-being between groomer and groomed, further cementing social ties,” Lameria writes.

Whenever an ape finds something to remove from another’s skin, they usually eradicate it by sucking it off their body, in a behavior that works precisely like a kiss. The kiss-like motion is the last final stage of removing each piece of debris so that every grooming session ends with a final kiss. As apes evolved into humans, we lost most of our hair, so grooming sessions became shorter and shorter. “Presumably, up until the ultimate point when two individuals simply performed the last step of grooming, latching on their lips to the other's skin but having discarded the hygienic (and by now obsolete) function of grooming,” Lameira writes.

So, when we kiss each other, we're building and strengthening bonds with someone else, much like we once did through grooming rituals—only now, it's a quicker, more straightforward gesture.

As Sam, the piano player, sang in “Casablanca,” “You must remember this: a kiss is just a kiss,” but Lameira's paper shows that a kiss is much more than we could ever know. A kiss is a behavior that goes back millions of years, an example of the importance that social bonding plays among humans and other primates.

It’s interesting to learn where this behavior comes from. But, after reading this, it’s probably going to make kissing feel a bit more awkward when you consider that you are mimicking a behavior that was once used to remove bugs from your lover’s skin.

5 things 'desire paths' - or human-made shortcuts - reveal about people

Going off the beaten path is a heavily studied phenomenon.

Gordon Joly & wetwebwork/Flickr

If you've ever walked through a public park or across a grassy college campus, you've definitely noticed the phenomenon. Inevitably, there's a paved path or sidewalk leading from Point A to Point B. And then, branching off of that path, is a well-worn patch of dirt where people have chosen to walk instead.

Often the unofficial path is more efficient or more pleasant, and it's just so inviting that you can't help but branch off and walk it yourself. These human-made shortcuts are called Desire Paths — or sometimes Cow Paths or Elephant Paths. (Named as such because big, lumbering animals like to take the shortest route between two points.)

Some people say Desire Paths occur when a design fails to connect with human behavior.

Which makes them incredibly useful for urban planners and other people who design walking paths! Desire Paths are studied heavily, and some places even choose to pave over them once they appear, making them more official. (While others intentionally block them off).

There are even cases where no paving was done until Desire Paths naturally formed — when crowds of people did the engineers' and urban planners' work for them.

from DesirePaths

People are absolutely fascinated by Desire Paths.

The subreddit devoted to them has over fifty-thousand members! There are massive groups on Flickr where people share photos of desire paths they find in the wild. And a recent X thread of desire paths racked up almost thirty million views.

Why is it that Desire Paths spark such a reaction in us? If I had to guess, it's because Desire Paths are small acts of rebellion. They are literally a visual representation of going off the beaten path. The symbolism is powerful in a world that can feel very mundane and predictable.

They're also something that we create together. No one single person creates a new path. They hold a collective wisdom that resonates deeply somewhere in our souls.

And they teach us about ourselves, believe it or not. Here are a few things we can learn about ourselves from Desire Paths.

1. We're not superstitious, but we're a little stitious.

There are lots of examples of Desire Paths forming around archways or leaning objects.

Sure, you could say people walk around so they don't bump their heads, or maybe to make room for passing cyclists.

But I like to think we just don't want to risk the bad karma.

from DesirePaths

2. Anything that gets in the way of a straight line is annoying.

If we're walking in a straight line, we generally would like to continue in that straight line.

A decorative circular garden right in the middle of the path might seem like a good idea — but only if you want to see it get trampled.

from DesirePaths

In the same vein, why walk in a complicated squiggly shape when we can just cut right across?

3. We like gentle hills more than stairs.

It's surprising and fascinating how often people will avoid going up and down stairs if they can cut through the grass instead.

Human beings' hatred of stairs is well-documented, but it's interesting to see it play out visually.

A path worn in the dirt next to stairs Gordon Joly/Flickr

Some studies estimate walking up stairs is twice as hard on the body compared to walking up a hill.

4. We don't like sharp turns.

If you know people, you won't be surprised to hear that we like to cut corners!

A dirt path next to sidewalk Dan Keck/Flickr

We're not robots! We don't like turning at right angles. Plus, if we're in a rush, a more efficient path saves us time.

5. We like feeling connected to the people that came before.

Holloways are a special sort of Desire Path, carved deep into forests and other nature. They are often ancient. They are ever-changing.

By walking through these paths, we become a part of them and a part of history.

A quote from Rebecca Solnit sums it up perfectly:

“Walking is a mode of making the world as well as being in it.”

So go ahead and take the road less traveled. Follow your intuition. You might be on to something, and it could be the beginning of a new and better path!

Science

People are sharing what they believe happens after we die. The responses are enlightening.

Here are 16 of the best responses.

A man is walking into heaven (or is he?).

One of the funniest and most bizarre things about being a human being is that we really know very little about what’s going on. Sure, many religious people are confident they know why we exist, where we came from and what happens after we die, but there isn’t a whole lot of evidence to suggest they’re correct.

However, even though we are at the center of an incredible mystery, most people are happy to go about their days without worrying about the basic nature of our existence. This has always been very strange to me. Why isn’t the nature of existence the No. 1 question on everyone’s mind the moment they wake up?

There is one thing we do know for sure: that we are all going to die one day. Some people believe that once we flatline we may get invited to heaven where we get to spend all eternity playing the harp, reuniting with old friends and relatives, and enjoying a pain-free, joyous existence.

But as the TV show “The Good Place” suggests, living a perfect life, free of suffering or challenges, eventually becomes pretty forking boring and pointless.

Mark Twain said it best in “Letters from the Earth”:

His heaven is like himself: strange, interesting, astonishing, grotesque. I give you my word, it has not a single feature in it that he actually values. It consists—utterly and entirely—of diversions which he cares next to nothing about, here in the earth, yet is quite sure he will like them in heaven. Isn't it curious? Isn't it interesting?

Many also believe that if there’s a heaven, there’s also hell where the folks who had a good time on Earth wind up. But wouldn’t that get boring, too? Just as one can get accustomed to living in constant beauty, one probably gets acclimated to the heat and suffering down below.

There are also some who believe in reincarnation, so every time we die we are born again as a different species. Cool if you’re a dolphin, bad news if you’re a dung beetle.

Then there are those who believe that nothing supernatural happens. Your consciousness shuts off and things are a lot like before you were born—absolute nothingness. That’s the least interesting option, but according to science, the most likely.

Reddit user throwawayacctlmaooo wanted to find out what posters on the forum thought about life after death, so they asked, “What do you legitimately believe happens after we die?” They received a ton of responses that were outside of the usual “go to heaven/go to hell” variety. What’s cool is that the posts show that a lot of people have widely divergent ideas about what happens after we die.

Here are some of the best responses to the biggest question in life.

1. You're a wave

"No idea, but there is this quote from the TV show 'The Good Place' that I really like and have found comfort in.

"'Picture a wave. In the ocean. You can see it, measure it, its height, the way the sunlight refracts when it passes through. And it's there. And you can see it, you know what it is. It's a wave.

"And then it crashes in the shore and it's gone. But the water is still there. The wave was just a different way for the water to be, for a little while. You know it's one conception of death for Buddhists: the wave returns to the ocean, where it came from and where it's supposed to be.'" — AlexEventstar

2. Our energy moves on

"Our energy — just like that of every living thing before us — will go on and become new things. Soil. Plants. Lions. Toilet paper. Space ship wheel arches. Dragonfly toes. We're all just part of the same system. Neither manufactured nor destroyed. We're just transferring that bestowed upon us from all those before. Death is life." — four__beasts

3. You've been there before

"Just like before you were born. Not good, not bad, just non-existence." — SniffCheck

4. No need to fear

"In the great words of Mark Twain: 'I do not fear death. I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it." — Eva__Unit__02

5. One more time

"When I think about it, I come to this very same conclusion. And that terrifies me. The only thing that is a little comforting for me is that, according to some research and according to some people who have experienced Near Death, just before full-on 'nothingness," you relive your life one last time, with an emphasis on the best moments in your life, all being overwhelmed with a feeling of love." — MrXANA91

6. Isn't this reincarnation?

"I think we just keep on hitting a randomize button and we manifest into something else, again and again endlessly." — FarOutSonOfLung

7. The great nothing

"In my opinion, nothing. Like being under anesthesia but never waking up and ceasing to exist." — throwayaacctlmaooo

8. Choose your own adventure

"I'd like to think we reset like a game and we could choose whether we get reborn or go to some sort of heaven or something." — No_But_Yes

9. We're energy

"I’d honestly like to believe that we all become energy. We move around the universe, maybe even become one with it until we are reincarnated again as something else on earth or a different planet." — cheese-emperor

10. Salamanders

"I think we are all reincarnated as salamanders." — Kyky716

11. New universe?

"I believe we go to another universe but that's just wishful thinking." — Zarek_Pumpkineater

12. Incomparable infinity

"I'm under the impression that death is a separate experience we can't comprehend. Like someone with vision will never truly know the concept of blindness or someone with hearing will never know the concept of deafness.

"You only experience it while you're doing it and I am currently experiencing being alive as a human. You don't know what it was like before you were born because you're obviously alive. Just like you don't know deafness because your ears work.
Beyond that, I believe the universe is in endless million-trillion year long cycles of growth and collapse and the fact that I exist at all means, throughout infinity, I am a guaranteed mathematic outcome and must repeat again." — bermudalily

13. Nothing

"Nothing. It's the only answer that makes sense. We ARE our thoughts. Our thoughts are in our brain. When we die, our brain shuts down. So our thoughts no longer exist. Anybody who believes in any form of an afterlife really needs to explain how we can have thoughts without our brain. And if they believe that's somehow magically possible, why do we have brains while still alive?" — joeri1505

14. You become fertilizer

"The same as when trees, plants, or other animals die, we decompose & feed the earth for something else to grow." — skev303

15. May the source be with you

"What I like to believe is that all life comes from a specific energy source and is returned there once we die. Sort of like a big pool of life, where all souls merge after death and cycle back into the world to be reborn. As for what we experience in that form I have no idea. But the entire world lives and functions on cycles, from the food chain to the weather cycle, eveywhere you look there is a cycle to maintain it. So it only makes sense life would work the same way." — doopster77

16. Star stuff

"Your surviving family gets all teary, then buries or burns your lifeless body. As the years pass, what atoms once made you, you, become all mixed up in other things, until much later on when the sun dies and engulfs the earth and all its atoms in a final dance of atomic death. Because we are all made of stars, and to them we will all return." — dbryar

Pennsylvania home is the entrance to a cave that’s been closed for 70 years

You can only access the cave from the basement of the home and it’s open for business.

Brian Marble/Facebook

This Pennsylvania home is the entrance to a cave.

Have you ever seen something in a movie or online and thought, "That's totally fake," only to find out it's absolutely a real thing? That's sort of how this house in Pennsylvania comes across. It just seems too fantastical to be real, and yet somehow it actually exists.

The home sits between Greencastle and Mercersburg, Pennsylvania, and houses a pretty unique public secret. There's a cave in the basement. Not a man cave or a basement that makes you feel like you're in a cave, but an actual cave that you can't get to unless you go through the house.

Turns out the cave was discovered in the 1830s on the land of John Coffey, according to Uncovering PA, but the story of how it was found is unclear. People would climb down into the cave to explore occasionally until the land was leased about 100 years later and a small structure was built over the cave opening.

The idea was to make it accessible to visitors and use the cave as a tourist attraction, and the small structure was eventually built into a two-story house. But it was closed to the public in 1954 after the land was purchased for limestone mining and it remained closed for nearly 70 years. (In the words of Stephanie Tanner, "How rude.") Sometime during that 70-year closure, the home that contains the cave was purchased by Dara Black, and in 2021, it reopened to the public.

Currently, the home is occupied by Black, but to gain access to the cave you can simply book a tour. The best part about booking a tour is that you only have to make a donation to enter. It's a pay-what-you-can sort of setup, but since someone actually lives in the home, you can't just pop in and ask for a tour. You have to go during the "open house" times available.

According to the Black-Coffey Caverns Facebook page, they treat the tours truly as an open house, complete with snacks and drinks. There's a waiting room area where people can chat and eat their snacks while they wait for the tour to start. They also offer cave yoga once a month. According to Uncovering PA, the tour takes about 45 minutes to complete and there are about 3,000 feet worth of passageways.

Imagine living on top of a cave and just taking strangers on a waltz under your floorboards essentially. It makes me wonder if the house is quiet at night or if you can hear echoes of the cave sounds while you're trying to sleep. From the Facebook page, it appears that the cave doesn't have any lights, but there were pictures with some Christmas lights mounted to the cave walls. Otherwise, you have to use flashlights.

Hopefully, no mischievous children decide to play hide and seek or you just might have to call in a rescue crew. Literally. But what an unbelievable "pics or it didn't happen" kind of story to tell. It's not every day you run into someone that has a door that leads you to an underground cave.

If you want to see what a cave tour looks like starting from the outside of the house, check out the video below:
