Neil deGrasse Tyson Just Answered the Game of Thrones Question That Everyone's Asking

Serial debunker of movies and TV Neil deGrasse Tyson took on Game of Thrones on Sunday evening, analyzing everything from the chains the army of the dead used to pull up dead dragon Viserion (wrong angle) to the dragons themselves (good wing span, though experts we spoke with say they're still too heavy to fly). And then he dropped an intriguing tweet that just might explain Ice Viserion's blue fire, which easily cut through the Wall:

Inverse's Yasmin Tayag took a deep dive into the physics of dragon fire after the season finale and concluded that, according to science, blue flames are the hottest of them all. Typical Game of Thrones dragon fire—the red, yellow, and orange kind—is the result of incomplete combustion. The color is caused by the fuel in the dragon's gut (likely carbon) releasing chemicals as gas in a process known as pyrolysis. Blue flames, though, mean complete combustion, which, according to Tayag, "can only occur when there’s plenty of oxygen available to allow a flame to get super hot, and the fuel being burned doesn’t release too many additional chemicals during pyrolysis that might lead to a different colored flame."

In August, Game of Thrones sound designer Paula Fairfield—perhaps in an attempt to answer viewers’ nagging question about whether Viserion was blowing fire or ice—told Vanity Fair’s Joanna Robinson that, “He’s just going at it and slicing with this. It's kind of like liquid nitrogen. It’s so, so cold. So imagine if that’s what it was, but it’s so cold it’s hot. That kind of thing.”

This could have big consequences if Ice Viserion and Drogon face off. "If the HBO series decides to follow these particular laws of thermal physics (and why should it when Thrones so flagrantly disregarded chain physics?!?), then Viserion will surely be at an advantage if and when he ever goes talon-to-talon with his brother Drogon," wrote Robinson in response to deGrasse Tyson’s tweet.

Game of Thrones's final season won't debut until late 2018 or 2019, so we have a long time to wait before we see which dragon's fire comes out on top.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

The Psychological Tricks Disney Parks Use to Make Long Wait Times More Bearable

No one goes to Disneyland or Disney World to spend the day waiting in line, but when a queue is well-designed, waiting can be part of the experience. Disney knows this better than anyone, and the parks' Imagineers have developed several tricks over the years to make long wait times as painless as possible.

According to Popular Science, hacking the layout of the line itself is a simple way to influence the rider's perspective. When a queue consists of 200 people zig-zagging around ropes in a large, open room, it's easy for waiting guests to feel overwhelmed. This design allows riders to see exactly how many people are in line in front of them—which isn't necessarily a good thing when the line is long.

Imagineers prevent this by keeping riders in the dark when they enter the queue. In Space Mountain, for example, walls are built around the twisting path, so riders have no idea how much farther they have to go until they're deeper into the building. This stops people from giving up when they first get in line.

Another example of deception ride designers use is the "Machiavellian twist." If you've ever been pleasantly surprised by a line that moved faster than you expected, that was intentional. The signs listing wait times at the beginning of ride queues purposefully inflate the numbers. That way, when a wait that was supposed to be 120 minutes goes by in 90, you feel like you have more time than you did before.

The final trick is something Disney parks are famous for: By incorporating the same level of production design found on the ride into the queue, Imagineers make waiting in line an engaging experience that has entertainment value of its own. The Tower of Terror queue in Disney World, which is modeled after a decrepit 1930s hotel lobby down to the cobwebs and the abandoned coffee cups, feels like it could be a movie set. Some ride lines even use special effects. While waiting to ride Star Wars: Ride of the Resistance in Galaxy's Edge, guests get to watch holograms and animatronics that set up the story of the ride. This strategy exploits the so-called dual-task paradigm, which makes the line feel as if it's going by faster by giving riders mental stimulation as they wait.

Tricky ride design is just one of Disney's secrets. Here are more behind-the-scenes facts about the beloved theme parks.
