Inspired by Harry Potter’s iconic invisibility cloak, these real-life invisibility shields can make anyone who hides behind them disappear into thin air.

Invisibility Shield Co. is a UK-based startup that has been working on an affordable invisibility mechanism for over two years. The company recently revealed a line of invisibility shields that rely on surprisingly simple technology to make users invisible to the naked eye. Apparently, the shield uses a “precision-engineered lens array” to deflect light from the subject sitting behind the shield away from the observer. The lenses are oriented vertically to allow light from the subject to diffuse when it passes through the shield. The light from the subject’s background is refracted towards the observer who cannot see the subject hiding behind the shield.

Souki Socks, a small sock factory in Japan’s Nara Prefecture, has devised a machine that allows people to knit their own socks by pedaling on a stationary bicycle.

Unless you’re a fan of knitting, making socks doesn’t exactly sound like a fun experience. This was the reality that the brilliant minds Souki Socks were confronted with when they set out to make sock-making exciting for the masses. Luckily, despite having the odds stacked against them, they managed to come up with an ingenious contraption that combined a mechanical sock knitting machine and a bicycle to allow virtually anyone to knit their own socks just by pedaling. Named “Charix,” the machine has been very popular with tourists ever since it was inaugurated in 2017.

If your idea of a nice meal out on the town happens to include rude restaurant staff that’s actually paid to insult and ridicule you, booking a table at Karen’s Diner should be on your priorities list.

Stipe Petic, a 57-year-old Bosnian man with no nordic background, was so impressed by the ‘Vikings’ TV series that he started calling himself Ragnar Kavurson and making axes for a living.

The Bosnian Ragnar claims that his fascination with Viking culture started with a binge-watching session of History’s hit series, ‘Vikings’. Coming back to his hometown of Tomislavgrad in southern Bosnia after ten years of working on construction sites in Germany, he became fascinated by the saga of the legendary hero Ragnar Lothbrok and his wife Lagertha. After changing his look to mimic that of a nordic warrior of legend, and borrowing the name of his favorite Viking character, Ragnar, the “Bosnian Viking” started making intricately decorated Viking axes and shields.

The Areia Preta beach in the Brazilian city of Guarapari is famous for its black sand which has external radiation levels of almost 400 times the normal background radiation recorded in the US.

Brazil has hundreds of miles of beaches, but none are quite like “Praia Da Areia Preta”, in Guarapari. The sand in this region, particularly the black sand, contains moderate quantities of monazite, a phosphate mineral rich in several rare-earth elements, including uranium and thorium. Research has shown that background radiation on Areia Preta can reach 175 mSv per year, or 20 μSv/h, while some spots, particularly those with lost of black sand, have radiation levels of up to 55 μSv/h. To put that into perspective, the average radiation exposure level across the United States is about 0.34 μSv/h, while an X-ray gives people a one-time exposure to about 100 μSv.

The western hook-nosed snake, a small snake endemic to the deserts of the United States and Mexico, is famous for the shape of its snout and for farting to confuse its enemies.

Cobras and rattlesnakes have their deadly venom, constrictors like pythons and Boa have their strong musculature, but the western hook-nosed snake doesn’t have either, so it relies on a more unusual defense mechanism – farting. When threatened, it emits rumbling air bubbles from the cloaca – the common opening for excretion at a snake’s rear end. Known and cloacal popping or defensive flatulence, this strange means of defense is designed to confuse predators long enough for the snakes to escape.

Japanese tech giant Kawasaki caused a lot of raised eyebrows at the world’s largest robot trade show in Tokyo, with Bex, a rideable robot goat.

The 2022 International Robot Exhibition featured a lot of ingenious creations, but few as attention-grabbing as Kawasaki’s latest invention, a robot goat that can carry approximately 220 pounds of cargo. Named after the Ibex, a species of large wild goat native to parts of Eurasia and Africa, the Kawasaki Bex can transport human riders or different materials, but it also has a fully modular top half, so it doesn’t need to be a rideable goat. But let’s be honest, why would you want to ruin a good thing? After all, what’s cooler than a robot goat?

As the name suggests, the Hummer H1 X3 is three times the size of a standard Hummer H1, making it the largest Hummer in the world, by far.

The Hummer H1 is one of the largest street-legal SUVs ever made, but it literally looks like a toy car next to the behemoth that is the Hummer H1 X3. Measuring 6.6 meters high, 14 meters long, and 6 meters wide (21.6 x 46 x 19.6 feet), this metal monster is the largest Hummer in existence, at least according to its owner, Sheikh Hamad bin Hamdan Al Nahyan, aka the Rainbow Sheikh, one of the most eccentric car owners in the world.

A Wisconsin dentist was recently found guilty of intentionally damaging his patients’ teeth so he could charge them more after fixing them.

61-year-old Scott Chamolli faces up to 10 years for each of his five healthcare fraud charges, and a maximum of five years for two other charges.

Lal Bihari is probably India’s most famous living dead, one of many people killed off in official records so that relatives can claim their possessions for themselves.

Killing off somebody on paper is apparently not that hard to do in India. All you need is some bribe money and local officials willing to do some dirty work in exchange for that money. Victims are usually people who have been away from their birthplace for a long time, and the culprits are greedy relatives trying to claim their land or their family homes. But once you’re dead in official records, proving that you’re actually alive is a much more difficult endeavor, especially when the people you are trying to convince are the very same who were paid to kill you off in the first place.

Lal Bihari’s story is probably the most famous example of a “dead man’s” struggle in India. His woes began in 1976, when he returned to his birthplace, the village of Khalilabad, in Uttar Pradesh, for residence, income and caste certificates, needed to secure a loan for his heirloom business. When the clerk first looked up at him and told him that Lal Bihari was dead, he smiled, but the clerk didn’t smile back…

Deinococcus radiodurans is listed in the Guinness Book of World Records as “the world’s toughest bacterium,” and it is fully deserving of that title.

Scientists discovered the red, spherical bacterium that later came to be known as deinococcus radiodurans about 70 years ago, when examining a can of ground meat that had spoiled despite having been sterilized by exposure to doses of radiation in the megarad range. Research would later show that this lowly bacterium can withstand 10,000 times the amount of radiation that would normally kill a human being, thanks to a miraculous ability to repair numerous DNA double-strand breaks in a matter of hours.

Ring-necked parakeets are native to the foothills of the Himalayas and temperate regions of North Africa, but for the past century and a half, they’ve also made a home for themselves in London.

No one knows exactly when and how London became a home for feral parakeets. In fact, there are so many urban myths tied to these green exotic birds that it’s hard to settle on just one explanation. Many of the theories going around on the streets of London as well as on the internet involve legendary artists like Jimi Hendrix or Audrey Hepburn, but no one can truly say how the birds came to the English capital. One thing is for sure, though – London’s parakeets are here to stay, they are thriving, and they are expanding, with recent estimates placing their number in the tens of thousands.

Most people go on cruise ships for vacations, but for Mario Salcedo, cruise ships have been his home for the last 23 years, and this continuous life on the water has made him “the world’s happiest man”.

Calling Mario Salcedo a “super cruiser” would probably be an understatement. The retired financier has been on hundreds of cruises in the last 23 years, and with the exception of a recent 1.5-year break due to the Covid pandemic, he has rarely spent more than a day or two on dry land. A native of Miami, Florida, Salcedo spent much of his life working for a number of large finance companies, including Federal Express, traveling the world and seeing other people have fun. Then, one day, he decided it was his time to have fun, so in 1997 he quit his job.
