Singapore Airlines has been hit hard by the economic consequences of the coronavirus pandemic. Last month, it announced plans to launch "flights to nowhere" that just take off, circle the airport, and then land.

Now, to put its grounded planes to good use, the airline is using the jetliners as pop-up restaurants. Since Singapore Airlines has an excellent reputation for in-flight food, this may draw customers. Fast Company reports:

Customers had the option of buying tickets in different classes, with a meal in a first class suite priced at $474 compared to an $39 economy class meal. Both meals will take place on planes at Singapore’s Changi Airport, which is the company’s hub. The airline says it will enforce social distancing, using only half of the 471 seats on the plane.

Potatoes have phosphoric acid. Insert a source of zinc and the two will react to produce a small amount of electrical current.

Very small. Will a potato run the video game Doom? No, but if you use about 700 potato pieces, YouTube user Equalo discovered, you can run Doom on a graphing calculator:

This was a long, difficult project that Equalo completed while working a full-time job. As a result, the potato pieces became moldy and stinky by the end of the six-day effort.

YouTube user Matthew Highton masterfully mined stock video archives and wove them into remarkably consistent recreations of TV show introductions. I'm especially impressed that there were appropriate demonic footage reels for Buffy the Vampire Slayer.

In this playlist, you can also find Highton's videos for The A-Team, Friends, Duck Tales, ThunderCats, and more.

There are parts of your body (or at least mine) that are not routinely displayed to the public. The roof of the mouth is an example. Indy Voet, a Belgian tattoo artist, has been inking tattoos in that remote location for five years. He tells Inked magazine that it's a tricky job that requires delicate handwork and a trusting client:

For this process, Voet uses a handpoking technique rather than a machine, explaining that the machine would be too harsh on this location and too difficult to get to. "I don't really use anything other than a needle and some dexterity, combined with the trust of my client."

Thankfully, it doesn't hurt too much to get tattooed on the roof of the mouth:

"Nine out of 10 people describe these tattoos as being almost painless or at least, very easy to handle. The other 10% mostly complain about jaw muscle aches, which seems logical."

Augmented reality (AR) systems overlay the world around the viewer with information displayed through a digital interface. Humans have used it for years. Although your dog won't be able to play Pokémon Go yet, researchers are developing ways that military dogs may be able to use AR headsets effectively. The US Army informs us:

In 2017, Dr. A.J. Peper started Command Sight, a small business based in Seattle, to bridge human and animal communication. Through conversations with current and former military operators he identified a need to increase the efficacy of communication between canine and handler. As a result, Command Sight built the first prototype of augmented reality glasses for military working dogs. [...]

The augmented reality goggles are specially designed to fit each dog with a visual indictor that allows the dog to be directed to a specific spot and react to the visual cue in the goggles. The handler can see everything the dog sees to provide it commands through the glasses.

Graphic designer Justin Bryant has a delightfully morbid imagination. In a series of six posters, he suggests that popular children's board games could easily be turned into horror films. Candy Land looks sweet, but hides a dark secret. Hungry Hungry Hippos are ready for lunch. And you definitely don't want to catch--or be caught-- by the Cooties.

You can see all of these posters at Born in Space.

Sure, you already follow him on Instagram and listen to his podcast. But now you can watch live, streaming video thanks to a camera invented by Vikram Iyer, a doctoral student at the University of Washington.

It's a remarkable technical achievement. Not only is the image sensor tiny, but it's mounted on a swinging arm that matches the direction of the insect's head, thus presenting a more realistic depiction of a bug's view of the world.

To save on battery life, the camera only turns on when an accelerometer is triggered and thus remains dormant when the beetle doesn't move. As a result, the camera can capture video for up to six hours.

How is this useful? Iyer described his invention as more useful for robotics than entomology. King 5 News quotes him:

“If you need to build a robot that can fit into small spaces, you need a way to navigate around that environment,” said Iyer. “And vision is one of the major ways people solve these problems.”

At the core, he said it’s essentially a tiny computing platform ready to be modified for different uses.

Master pie artist Jessica Clark-Bojin (previously at Neatorama) is challenging members of the Instagram piecrafting community to devise a #MonsterPie for Halloween. One of her own contributions is this frightening Jack-o-lantern pie that offers more than a hollow interior. Her whole Instagram page is worth exploring, as she has already become internet famous for such works as Dark Crystal and baby Yoda pies.

Iron Cat is here to save the world. He's ready, now that he has a 3D printed helmet that even pops open to reveal the (very patient) cat's face on demand. Cathode the cat of Besançon, France models the latest superhero costume.

This seal is well-known among the people who live along the River Witham in Anton's Gowt, Lincolnshire, UK. He is called Dandy Dinmont (and he looks the role) and has been a resident since 2017.

Recently, Dandy visited a group of paddleboarders. Lincolnshire Live reports that he climbed on two of the boards and stayed there for about 10 to 15 minutes.

Do you have a romance that reminds you of Harley Quinn and the Joker? Then Etsy seller Nenad Cicmil has the perfect wedding ring for you. If you have a different sort of relationship, like that of Spawn and Wanda Simmons or the Punisher and Maria Castle, then this jeweler has more options for you.

For me, I'll take this black gold Batman ring for a gritty reboot marriage. I'd propose in a forced gravely voice, like Christian Bale struggled to use in The Dark Knight film trilogy.

Mezerg is a French musician and instrument designer who builds unique instruments, including a watermelon, a theremin ring, and an electric drill.

His latest creation is the Piano Cocktail. Selected keys open the stops on liquor bottles, allowing the musician to play a cocktail into existence. You can also mix a specific recipe. It just might sound weird.

Are you clothed above the waist right now? If so, why? Unless you're a klutz with your webcam, you have nothing to worry about. Right now, I'm wearing pajama shorts with a dress shirt because no one in my upcoming Zoom meeting will see my lower body.

Fashion brands are catching up with this trend. The BBC reports:

A "waist-up" focus has been noticed at both Milan and London Fashion Weeks, with detailed necklines and relaxed trousers. [...]

"Fashion is about reacting to reality," said Miuccia Prada, head designer of Prada, at its virtual Milan fashion show. "During lockdown, I realised how important technology is and how it is impactful for us, and in some ways, an extension of ourselves."

"The tunic tops and roll necks, with the brand's famous triangle logo blown up and placed directly below the neckline, will certainly catch the eye of your fellow Zoomers," Jane McFarland, fashion director at The Sunday Times, said of the collection.
