Correction: Our staff producer pronounced the the Japanese word "ōbōn" incorrectly in this episode. It is pronounced OH-bohn not oh-BAHN. Let us be the first to wish you a Happy Flag Day, beautiful nerds! Anyone who has listened to 99% Invisible regularly knows we have a thing for flags, which can beautiful things that give communities something symbolic to rally around. This year, we decided to get the celebration started early then keep the party going with two whole weeks of flag-related stories. They look like normal Japanese flags (hinomaru) at a glance, but upon inspection, they are covered in handwritten notes often radiating outward in kanji from the central red circle (a sun against a field of white). Different messages are written in different hands directly on the fabric. These so-called "good luck flags" were gifted to soldiers, particularly during WWII, as part of a send-off from loved ones -- and their name in English comes from one of the most commonly written phrases on them: good luck. Antarctica is a wonderfully strange place, and not just because of its infamously frigid climate. This huge landmass doesn’t have an independent government or even a permanent human population. It also has a lot of flags, though strangely: no single official one.

Most people probably don't spend a lot of time thinking about their toilets, but they are both a modern marvel while also being somewhat of a failure of systems design. On the one hand, it has created a vast sanitation system that has helped add decades to human lifespan by reducing disease. But on the other hand, less than half of the world’s population can access a toilet that safely manages bodily waste, including many right here in the United States. We use about 100 trillion gallons of water for toilets every year at a time when water is becoming more scarce. While we see radical technological change in almost every other aspect of our lives, we remain stuck in a sanitation status quo—in part because the topic of toilets is taboo.

Today, Berlin is one of the premier destinations for techno music fans. People come from all over the world to party all night to the rhythmic beat of Berlin's club scene. And this music that the city is most famous for developed in large part because of the thing the city is most infamous for: the Berlin wall, which divided the city into east and west for almost thirty years. When the wall fell in 1989, everyone was euphoric and parties started popping up everywhere. East Berlin was like a big playground of derelict buildings. It wasn't just the abandoned apartments. There were also former military sites and factories that had been shut down and buildings that had been condemned. And these places were perfect for techno.

If you look around you right now, about 90% of what you’re looking at came to you onboard a cargo ship—your television, your sofa, most of the stuff in your kitchen. But as the number of these cargo ships has increased, so has a problem: workers stuck on ships that have been completely abandoned by the owners, leaving them stranded out at sea without basic supplies like food. In some cases, seafarers (that's the industry term for cargo ship workers) have been stuck on these abandoned vessels without enough supplies for months, or even years. Abandoned Ships This episode was produced in collaboration with the podcast Kerning Cultures, a podcast that makes audio stories - like this one - from the Middle East and North Africa.

If you live in an American city and you don’t personally use a wheelchair, it's easy to overlook the small ramp at most intersections, between the sidewalk and the street. Today, these curb cuts are everywhere, but fifty years ago -- when an activist named Ed Roberts was young -- most urban corners featured a sharp drop-off, making it difficult for him and other wheelchair users to get between blocks without assistance. Curb Cuts plus a special announcement from Roman Mars about the future of 99pi.

On the show this week, we’re bringing you an episode of a new podcast called, La Brega. And to tell us all about the series is Alana Casanova-Burgess. Casanova-Burgess traces back the story of the boom and bust of Levittown, a massive suburb that was founded on the idea of bringing the American middle-class lifestyle to Puerto Rico during a time of great change on the island. Casanova-Burgess (herself the granddaughter of an early Levittown resident) explores what the presence of a Levittown in Puerto Rico tells us about the promises of the American Dream in Puerto Rico.

Kurt and Roman talk about icebergs and how we visualize them all wrong. Plus, we visit a classic 99pi story by Emmett FitzGerald about visualizing dinosaurs. At least for the time being, art is the primary way we experience dinosaurs. We can study bones and fossils, but barring the invention of time travel, we will never see how these animals lived with our own eyes. There are no photos or videos, of course, which means that if we want to picture how they look, someone has to draw them. The illustrated interpretation of dinosaur morphology and behavior has had a big impact on how the public views dinosaurs and it's gone through a couple of key turning points, including a more recent push for more speculative paleoart.

Since the mid-1970s, almost every jazz musician has owned a copy of the same book. It has a peach-colored cover, a chunky, 1970s-style logo, and a black plastic binding. It’s delightfully homemade-looking—like it was printed by a bunch of teenagers at a Kinkos. And inside is the sheet music for hundreds of common jazz tunes—also known as jazz “standards”—all meticulously notated by hand. It’s called the Real Book. But if you were going to music school in the 1970s, you couldn’t just buy a copy of the Real Book at the campus bookstore. Because the Real Book... was illegal. The world’s most popular collection of Jazz music was a totally unlicensed publication. The full story of how the Real Book came to be this bootleg bible of jazz is a complicated one. It’s a story about what happens when an insurgent, improvisational art form like Jazz gets codified and becomes something that you can learn from a book.

More than 100,000 people die every year from snake bites. Snake venom can have up to 200 different toxins inside it and each toxin has a different horrible effect to your body. Some attack your muscles, while others attack your nerves. And sometimes two different toxins can work together to form an even more sinister combination. Part of the reason people are dying is because they're not getting antivenom - the medicine required to fight these horrible toxins - fast enough. The system we have to create snake antivenom is a time-consuming and inefficient process that basically hasn't changed for more than 100 years.

In the 20th century, humans became very good at the control of nature, but now that we’ve spent some time with the consequences, such as species extinction and climate change, humans are focused on the control of the control of nature. In this episode, Elizabeth Kolbert, author of Under a White Sky, talks about everything from the introduction of poisonous frogs in Australia to launching diamond dust into the stratosphere.

Back in the early 1990s, movie theaters weren't that great. The auditoriums were cramped and narrow, and the screen was dim. But in 1995, the AMC Grand 24 in Dallas changed everything. It was the very first movie megaplex in the United States. This is the gigantic, neon, big-box store of moviegoing that we're all used to today, and it's easy to dismiss as a tacky ‘90s invention. But the megaplex—specifically this first megaplex in Dallas—upended the entire theater business and changed the kinds of movies that got made in ways you might not imagine. The Megaplex!
