A 22-year-old spent his life savings not on a house, but on a jungle.

There comes a time in every young person's life where you find yourself facing down the path laid out for you. A path filled with all things you're "supposed" to do: get a college education, land a good job, make enough money so you can save up and eventually reach the mountaintop of buying your own home. Then…who knows.…

The problem is that settling down and buying property has become ridiculously, ludicrously out of reach for a lot of young people. Price-to-income ratios are the highest they've ever been in the history of the United States, and many of the new generation of adults who have achieved the dream of owning their own home have found it to be... a trap! Yes, there are a lot of amazing benefits to being a homeowner, but it can also be a massive drain on your finances, your time, and your freedom.

One Gen Z man is doing things a little differently. Instead of investing in his first house, he spent his life savings on 7.5 acres of undeveloped jungle in Colombia.

Twenty-two year old Robert Lennox-Hvenekilde from Denmark has always been an adventurer, filming his outdoorsy-escapades on TikTok for years. But a recent trip to Colombia left the Gen Z-er inspired to take his interest in nature to the next level.

"[I] realized that there were a lot of people living in these areas of the world who were maybe not rich in an economic sense, but they just seemed extremely free and to have an extremely high quality of life," he told Newsweek.

He decided to do something a lot of people only dream or fantasize about: live in Colombia, among nature, and create a sustainable homestead for himself. After months of researching, networking, and negotiations, he was able to purchase three hectares (or 7.4 acres) of undeveloped land for about $40,000. That equates to roughly five or six football fields, for reference.

The jungle land Lennox-Hvenekilde now calls home features a fresh water stream, avocado and other fruit trees, and sugar cane.

He's currently building a small structure on the land to live in, and he plans to be a good caretaker of the land. Outside of harvesting fruit and avocado to eat and sell, he says he'll continue to plant and nurture native plant species to provide a habitat for the several species of endangered monkeys living there. Lennox-Hvenekilde also says his property came with special trees planted specifically for wood production, which he's using to create his dwelling.

"I would not cut down any of the native jungle," he says.

Watch him give an amazing tour of his new home here:

Nearly two million people were fascinated by the wild video. Many were inspired by a way of life they'd previously thought completely unattainable.

"Dream life"

"can i come join you... sounds amazing"

"Bro made the best decision of his live"

It looks incredible on camera: the vibrant greens of the rainforest, working with your hands instead of staring at a computer all day, never having to commute or deal with rude strangers out in public. (Where do I sign up!?)

Still, others had mixed feelings:

"Please take care of the land and his water. Is our job to protect our nature. Plant trees and native flowers," one person implored.

More than a few commenters were uncomfortable with an outsider buying up endangered jungle land in a foreign country, likening it to gentrification.

Lennox-Hvenekilde's response has been that it's better for someone like him to take a small piece of the land for living, and harvest and care for the rest. Conversely, mass farmers burn down hundreds of thousands of acres of rainforest every single year in Colombia to make room for their crops. Compared to that, the 22-year-old's impact will be extremely minimal.

We've all had the fantasy at one time or another. Disappear, leave our entire life and Earthly possessions behind, and flee deep into nature. Live off the land. Create a simpler life for ourselves. Be happy.

In fact, and perhaps unsurprisingly, interest in off-grid living has been steadily growing in popularity due to factors like rising costs, fierce political division, and an increasingly hectic and stressful modern lifestyle.

For most of us, though, the thought remains a fantasy. As appealing as it sounds, the idea of actually saying goodbye to our career, friends, family, and human pleasures is a little frightening. Even more so when we realize that living off the grid is a ridiculous amount of work. Sourcing our own food and fresh water? Having little to no access to medical care if we were to get injured or sick?

It took a lot of bravery for Lennox-Hvenekilde to take such a big leap the way he did. And his journey is still not without its dangers. His viewers worry he might have run ins with the infamous Colombian drug cartels, which operate in the rainforest growing coca, which is used to make cocaine. And then there are all the bears, jaguars, and creepy crawlies.

"But how are the spiders?" one commenter asked Lennox-Hvenekilde. "Big," he said.

Yeah, on second thought, maybe that commute doesn't sound quite so bad. But kudos to him for showing us all what's possible.

Weather reporter shares 'forced convection' hack that'll cool your hot car faster than A/C

You may look a little funny, but it beats sweating in your seat.

A woman in a hot car.

It’s remarkable how, when it gets a little warm outside in the summer, the interior of your car can become a blazing inferno. A big reason for the discrepancy between the outside air temperature and the interior of your car is the same reason the planet is getting warmer: the greenhouse effect.

When you close your car windows and it's warm outside, the heat can’t escape because longwave radiation can’t pass through windows as easily as shortwave radiation. That’s why temperatures can go from comfortably cool when you get out of your car to blazing within minutes.

In fact, if it’s 80 degrees outside, it only takes 10 minutes for the car’s inside temperature to rise to 99 degrees and an additional hour to reach 137 degrees. That’s why it’s important never to leave your pet in the inside of your car, even when it feels cool outside.

How to cool a hot car in the summer

So, how do you cool your car down when it feels like a volcano inside in the middle of summer? Victoria Fenn Alvarado, a reporter with Canada’s The Weather Network, shared a science-based hack to cool your car even faster than blasting the air conditioner. First, you open the passenger-side window down. Then you open the driver's side door and step outside of the car. "Open and close the door paridly, about seven to 10 times. Once you complete his step, you can step inside your vehicle, and now you can drive away comfortably," Alvardo said.

It may look unusual to others in the parking lot to see you using your car door like a massive fan, but the hack is effective because it utilizes forced convection to replace the hot air with cool, fresh air. “Opening and closing the door acts as a pump, allowing warm air to exit rapidly. Paired with having the window open on the other side, this motion creates a pressure drop inside the vehicle, pulling in outside air, essentially replacing the warm air with fresh air,” Alvarado continues.

Hannah Fry further explained the phenomenon in a viral TikTok video. Fry is Professor of the Public Understanding of Mathematics at the University of Cambridge and the host of numerous popular podcasts and television shows.

How to cool your hot car using forced convection

@fryrsquared

That age-old dilemma of choosing between having a non-sweltering car or baffling a passerby because you look like a fool who doesn't know how to use a door


“The reason why it works is that when you open and close the door, especially if you do it quickly, the door, as it's moving outwards, it sweeps out all of the air that's in its way, creating this sort of area of low pressure that you get here,” Fry said. “And then that sets up something called bulk flow, which is where all of the hot, sweaty, horrible air inside the car is drawn outwards.”

The hack is one of the strange things that seems obvious, but most people probably haven’t considered. However, once you see it in action, it’s impossible not to think: Why didn’t I think of that? Here’s to enjoying the rest of your summers, knowing that even if it gets a bit warm outside, you always have a cool car to look forward to.

Why is text reversed in mirrors?

Have you ever wondered why text shows up backwards in a mirror? It's confusing to our brains because it doesn't seem like anything else is flipped like that. If we turn our head, it doesn't move the opposite direction in a mirror. Or does it? After all, right-handed you is actually left-handed you in the mirror. Right? (Wait, is that right?)

Mirrors can be confusing, despite not being very complicated. A mirror image is simply a reflection of what's before it. But when someone else is looking at us head on, they don't see text in reverse, so why don't we see what other people see when we see ourselves in a mirror?

(If you think this is a super stupid question with a super obvious answer, congratulations. Pat yourself on the back and scootch along so the folks who don't fully grasp the physics of mirrors can enjoy a demonstration that makes it a little easier to understand.)

"Why do mirrors reverse text?" asks the creator behind @humanteneleven on YouTube. "You might think it's just a property of mirrors—they flip things from left to right—but that's not true." He then picks up a metal arrow to show that it points the same direction in the mirror as it does in real life. So why is the text flipped when the arrow isn't?

- YouTube www.youtube.com

He then holds up a book to show how the text on the book cover appears backwards, just like the shirt. But when he holds up a Ziploc bag with the word "HELLO" written on it, the word shows up properly.

That's because he had to flip the book over to see the cover text in the mirror. The baggy he could just hold up and see the letters through the transparent plastic, just as we see them in real life. If he flips the baggy over like he did the book, the text shows up backwards in the mirror, just like it does in real life.

"So it's actually not the mirror that's flipping anything from left to right," he says. "It's the human."

People appreciated the simple, straightforward explanation and demonstrations.

"One of the most insightful demonstrations I've seen. It's simple and explains the phenomenon. Well done!"

"While I've heard this explanation many times before, I've only recently seen it demonstrated with text-on-transparency, which is what really makes it click. Great video!"

"Love these sorts of demonstrations. It’s a bit of a complicated one, but I love seeing how different people's minds work when explaining simple things like this. My kid explains it with “left is on the left, right is on the right, things aren’t flipped, they are mirrored” but it’s true that you are the one who flips things and I’ve never thought of it that way before."

"Oh my God, I haven't understood explanations from physics videos about why mirrors flip but this, gosh this helps."

Mirrors have been hilariously befuddling people in other videos as they try to figure out how the mirror knows what's behind a barrier placed in front of objects.

@sarahcoome

this is kinda creepy 👀 #mirror #relatable #creepy

Is this something all of us should probably have learned in high school? Yes. Do all of us remember everything we learned in high school? No. Does the scientific explanation make perfect sense to everyone even if it's explained in detail? Um, no.

Like the reversed text question, having a simplified explanation that doesn't fully get into the nitty gritty physics and geometry of how mirrors work is helpful for some folks.

- YouTube www.youtube.com

For those who do want a bit more scientific substance to their explanations, this next video does a good job of giving a bit more detail while still keeping the explanation simple. It even uses a visual diagram to explain:

- YouTube www.youtube.com

And for those who say, "This is so basic! How do people not understand this?" here's a video that really does get into the nitty gritty physics and geometry of how mirrors work, diving into ray and wave optics, photons, wave functions, probability, and quantum mechanics. It's only 12 minutes, and it manages to entertain while explaining, but it certainly blows the notion that understanding mirrors is super simple.

As one commenter wrote, "I thought I understood mirrors. I understand mirrors even less now. And that's a compliment."

Isn't science fun?

Innovative farm in Virginia can grow 4 million pounds of strawberries on less than one acre

This method uses 97 percent less land and up to 90 percent less water than conventional farming.

A new way to grow strawberries with less land, less water, and more berries.

Strawberry farm harvests aren't something most of us calculate on a regular basis (or ever at all), but the numbers from a strawberry farm in Richmond, Virginia are staggering enough to make it worth an old-school word problem. If the average American eats 8 pounds of strawberries a year, and an average strawberry farm yields approximately 20,000 pounds of berries per acre, how many people could a 200-acre strawberry field feed?

I won't make you do the math. The answer is 500,000 people. But what if a crop that size, providing enough strawberries for half a million people, could be grown on just one acre instead of 200? It's possible. You just have to go—or rather grow—up, up, up.

Indoor vertical farm company Plenty Unlimited knows a lot about growing up. In fact, it's their entire business model. Instead of the sprawling fields that traditional farming methods require, vertical farms have a much smaller land footprint, utilizing proprietary towers for growing. Plenty has used vertical farming methods to grow greens such as lettuce, kale, spinach, and more for years, but now it boasts a vertical berry farm that can yield a whopping four million pounds of strawberries on a little less than an acre.

Growing indoors means not being at the mercy of weather or climate unpredictability (barring a storm taking out your building), which is wise in the era of climate change. Unlike a traditional greenhouse which still uses the sun for light, Plenty's indoor vertical farms make use of the latest technology and research on light, pinpointing the wavelengths plants need from the sun to thrive and recreating them with LED lights. Plenty farms also don't use soil, as what plants really need is water and nutrients, which can be provided without soil (and with a lot less water than soil requires). Being able to carefully control water and nutrients means you can more easily control the size, taste and uniformity of the berries you’re growing.

If that sounds like a lot of control, it is—and that idea might freak people out. But when a highly controlled environment means not having to use pesticides and using up to 90% less water than traditional farming, it starts to sound like a solid, sustainable farming innovation.

Plenty even uses AI in its strawberry farm, according to its website:

“Every element of the Plenty Richmond Farm–including temperature, light and humidity–is precisely controlled through proprietary software to create the perfect environment for the strawberry plants to thrive. The farm uses AI to analyze more than 10 million data points each day across its 12 grow rooms, adapting each grow room’s environment to the evolving needs of the plants – creating the perfect environment for Driscoll’s proprietary plants to thrive and optimizing the strawberries’ flavor, texture and size.”

Plenty even has its own patent-pending method of pollinating the strawberry flowers that doesn’t require bees. Even just the fact that this enormous crop of strawberries will be coming from Virginia is notable, since the vast majority of strawberries in the U.S. are grown in California.

Plenty's Richmond farm is currently growing strawberries exclusively for Driscoll’s.

“Partnering with Plenty for the launch of the Richmond Farm allows us to bring our premium strawberries closer to consumers in the Northeast, the largest berry consumption region in the U.S.,” Driscoll’s CEO Soren Bjorn said in a press release. “By combining our 100 years of farming expertise and proprietary varieties along with Plenty’s cutting-edge technology, we can deliver the same consistent flavor and quality our customers love—now grown locally. This new innovative farm is a powerful step forward in continuing to drive category growth in new ways for our customers and consumers.”

Is Plenty’s model the farm of the future? Perhaps it’s one option, at least. The more we grapple with the impact of climate change and outdated, unsustainable farming practices, the more innovative ideas we’ll need to feed the masses. If they can get four million pounds of strawberries out of an acre of land, what else is possible?
