Imagine you’re at a Six Flags theme park, and after waiting an hour in line, you sit down in the front seat of The New Revolution, a looping roller coaster that hits top speeds of up to 55 miles per hour. The ride operator calls, “All clear,” your coaster takes off from the loading station, and you make your way up a lift hill. As the car goes clack clack clack, you realize that the lap bar was never secured and there’s no way back.

What would happen if you were stuck on a looping roller coaster and the harness stopped working? Could you hold on to the person securely seated next to you and make it through the loop, or would you be thrown out of the car for what would be a tragic ending? Popular YouTuber Zach D. Films, who specializes in digital recreations, showed what would happen if you rode a looping roller coaster without a harness, and the good news is that there’s a decent chance you will survive. (Not that you'd want to try, though.)

What would happen if I rode a rollercoaster without a harness?

“If the bar came loose while you were riding a roller coaster, you'd probably expect to immediately fall out, but that probably wouldn't happen,” Zach D. begins his video.

According to Zach D., the competing forces of gravity and the speed at which you’re moving counteract each other, most likely keeping you safely in your seat. “You see, as you're being pulled into the loop, gravity tries to pull you down towards the ground, but because of the speed you're going and the direction of the tracks, a special force actually pushes you further down, outweighing the pull of gravity and keeping you in your seat,” Zach D. says in his video.

Another example of these forces is filling a bucket with a few inches of water, attaching a rope, and swinging it around your head. If you forcefully spin the bucket, the water will remain inside, even without anything to restrain it from falling out.


Even though science shows that it is possible to ride a looping rollercoaster without restraints, there aren't many people out there who want to try it. In November 2024, a passenger on the Desert Storm coaster at Castles and Coasters in Phonix, Arizona, claimed that his restraint released while he was on the ride. The restraint failure happened as the coaster climbed its first lift hill so he could exit quickly and make it to the emergency stairs near the coaster's peak.

"We started going up, everything seems to be OK. And then, when we get closer to the top, I hear a click. Different from the click of the roller coaster going up on the chain," he said. "So I check my bar, and when I pushed it, it released. It opened." The incident was caught on camera, and the footage is chilling.

While the idea of riding a roller coaster without a lap bar is horrifying, Zach D. proves that physics may be your unexpected friend in case of a lap bar failure. That being said, let’s keep those restraints locked and double-checked. Roller coasters are meant to be fun, not a test of your centrifugal force knowledge.

The dogs that saved the day.

Dogs are keen observers of the human condition. They can become very attuned to our daily behaviors and have the ability to recognize our facial expressions. A dog's amazing sense of smell also gives them a unique window into our health and emotions.

A dog's sense of smell is up to 10,000 times more sensitive than a human's. That gives them the ability to notice if we are ill by recognizing the changes in our body chemistry. They can also tell if we're depressed by noticing changes in our feel-good hormone levels. It's why dogs are known for nuzzling up to people when they feel down.

In short, dogs are much smarter than we realize.

A pair of dogs in England knew when something was wrong with their owner, and they just may have saved his life.

A 71-year-old man was walking his two dogs, a golden retriever and a lack labrador, one weekend in October 2021when he became unconscious and collapsed. The man and the dogs were hiking through Braithwaite How, a mountain summit in the Cockermouth to Newlands region in the northern part of the country.

Braithwaite How has an elevation of 564 feet.


After their owner fell to the ground, the two dogs broke up into a rescue team. The black labrador ran down the trail and found a hiker who had walked past them a few minutes before. The labrador barked and motioned for the woman to follow it down the trail.

While one dog was out getting help, the loyal golden retriever stayed by the man's side to protect him and keep him company. How's that for teamwork?

When the woman found the man, the golden retriever was right by his side. She then called the emergency number (999) for assistance.

The dispatcher summoned the Keswick Mountain Rescue Team who sent out a team of 12 people. By the time they arrived, the man had regained consciousness and felt well enough to walk down the hill into an awaiting ambulance. He was then taken to the hospital for further checks.

The rescue team was amazed that his dogs were able to coordinate a two-dog rescue plan to keep him safe. They thanked them for their bravery on Facebook.

"Many thanks to the passing walker and the amazing dogs," the rescue team wrote.

The man who collapsed did a good job in picking the right dogs to accompany him on a hike. Labradors are known to be one of the smartest dog breeds and golden retrievers are among the most loyal.

Let's hope that both dogs got a bowl full of treats when they got home that night because they are a wonderful example of why dogs are known as "man's best friend."

Expert explains why turning your phone off every day could protect you from getting hacked

Pulitzer Prize winning investigative journalist Ronan Farrow shares how this simple tip can offer protection in a time of less-than-stellar privacy regulations.

He also explains why tin foil might not be the best strategy for privacy.

There are just so many ways for important information held on your phone to be swiped—from subscription based apps that secretly send private customer data to Facebook to fake accounts that get your friends to invest in some kind of fake crypto.

And of course—this is more than a modern day inconvenience. It poses real threats to democracy and global human rights, which is why so many are calling for more regulations and safeguards. Of course, as with most regulations, change isn’t coming fast. Which isn’t good news, considering how rapidly technology evolves.

However, Pulitzer Prize winning investigative journalist Ronan Farrow has an incredibly simple tip for preventing our phones from being hacked: Turn them off more often.

While appearing on the Daily Show to promote his new documentary, Surveilled, Farrow told correspondent Desi Lydic that we as a society should be "freaking out" more about the lack of government restraints about spyware technology, saying that it could turn the country “into an Orwellian surveillance state,” affecting anyone who uses a device, essentially—not just political dissidents.

But, as Farrow noted, turning your phone off and on every day is an easy way to protect yourself, since most current forms of spyware “will be foiled by a reboot.” And even if you aren’t, say, a journalist of political activity (i.e. common targets for malware), you’re thwarting apps from monitoring your activity or collecting your data. And better still, you’re making it more difficult for hackers to steal information from your phone. Privacy protection aside, it’s a great way of just keeping your device healthy. Basically, it seems like the age-old solution for virtually all tech issues still holds up.

There are a few other things worth turning off now and then, such as bluetooth and location devices when you’re not using them, according to the NSA. In addition, Farrow also suggested keeping devices updated, and perhaps most important of all, actually writing to your representative about the issue.

However, when it comes to wrapping devices in tinfoil as a makeshift Faraday cage…that might not be the best use of one’s aluminum.

“Experts vary on exactly how effective that approach is,” Farrow told Lydic, just before quipping, “we need better policies. Not just better tinfoil.”

Expanding on Farrow’s 2022 New Yorker investigative exposé on the notorious spyware Pegasus, Surveilled delves into the multibillion-dollar industry of commercial spyware and its potential threats, making it evidently clear that this is not an issue for the elite few, or one to ignore until the future.

Waterproof mascara is causing eye damage according to optometrists

Eyes are a very sensitive part of the body, they quickly remind people of that when a spec of dust dares to sneak beneath the eyelid. The near microscopic dust particle suddenly feels like a large piece of spiked gravel refusing to dislodge itself no matter how much our eye waters trying to release it. The same goes for pretty much anything that makes its way into your eye.

Your own eyelashes that are supposed to serve as sentries standing guard to keep things out of your eyes sometimes betray you by falling directly into them. Just about anything can cause eye irritation and makeup is no different, especially if you rub your eyes while wearing it. But optometrists are warning against one particular type of eye makeup–waterproof mascara.

Yes, one of the greatest makeup inventions to come out of the twentieth century. Though the first version of waterproof mascara made in 1938 contained turpentine which of course resulted in unpleasant reactions, it was perfected in the 60s. No more worries about looking like a raccoon if you're caught in the rain or worse, have your feelings hurt and begin to cry. The popularity of the cosmetic exploded once the toxic ingredient was removed, yet eye doctors are saying to stay away. Why?

Several optometrists have taken to social media and YouTube over the years to discuss the risk of wearing waterproof mascara and eyeliner.

Dr. Gurleen Dhanoa explains, "it's right there in the name, waterproof mascara. Waterproof meaning it will not breakdown when in contact with water and our tear film is mostly comprised of water," she says before continuing to answer a commenter's question. "So when waterproof makeup enters the eye and tear film, which is inevitable, makeup is going to get into the eye, it doesn't breakdown and then it has nowhere to go but into the structures."


Once the waterproof makeup enters the structures of the eye it can cause a lot of damage, inflammation and irritation. This can cause people a lot of frustration because they may constantly feel like something is in their eyes which means more rubbing of the eyes leading to more irritation.

Ophthalmologist, Dr. Rupa Wong says, "if you do use waterproof makeup just remember to remove it thoroughly, it does take a little bit more work than regular eye makeup but you want to remove your eye makeup every single night. Don't be lazy, this is important because otherwise you can be prone to infections, inflammation, lash mites, none of the stuff that you want."


Several eye doctors have cited studies and their own experience seeing patients experiencing eye irritation as the result of waterproof mascara getting into the tear film of the eye. One doctor shares that his patient hadn't worn mascara in over ten years yet when he looked under her eyelid, the small black specs from that previously worn mascara were speckled throughout her eye's tear film. But how on earth do you get the mascara out of the tear film once its embedded?

Monica M. Dweck, MD, an ophthalmologist at the New York Eye and Ear Infirmary of Mount Sinai tells Ophthalmology Advisor, that improper removal of eye makeup and sleeping in eye makeup can clog the meibomian glands which can lead to meibomian gland dysfunction to which there is no cure. “It can be managed, and it can be controlled, but there’s no cure.”


@doctoreyehealth Did you know!? —> Mascara and other eye makeup products can sometimes get trapped under the eyelid and be absorbed into the eyelid tissue. It’s essential to be cautious when applying eye makeup and to remove it thoroughly using gentle makeup removers specifically designed for the eyes. Additionally, practicing good eye hygiene and avoiding excessive rubbing or touching of the eyes can help reduce the risk of makeup particles getting trapped under the eyelid and absorbed into the eyelid tissue. If you ever experience discomfort or notice makeup residue accumulating under your eyelid, it’s a good idea to consult with an eye care professional for guidance and proper care.

The meibomian glands help produce the oil needed to make tears which are constantly produced by your eyes to keep them from drying out. But when speaking to the Ophthalmology Advisor, Dr. Di Meglio reports that they can die out when makeup is consistently applied to the waterline. "If those glands die out, they can be gone forever… If you’re putting eyeliner along there, you’re giving yourself a little bit more of a chance of having gland dysfunction. If the oil stays stagnant…the glands themselves can atrophy.”

Waterproof mascaras and other eye makeup may be fantastic inventions to help keep things from running down your cheeks on humid or rainy days but the risk of wearing it daily may be too much for some people. Whether you should wear it or not is split amongst the different eye doctors with some saying don't wear it at all and others saying occasional use is fine as long as you remove it properly and avoid ever sleeping in it. It's up to each individual person to decide if they're willing to take the risk.
