- From a doctor who swallowed Yellow Fever vomit to prove a theory, to another who stitched together a two-headed dog, history's boldest experiments reveal just how far some minds will go; buckle in for a flying lawn chair ride, hear sound played through a dead man's ear, and witness a billionaire's bloody hunt for immortality; these are the maddest minds-and their most unbelievable experiments.
- Uncover the wild beginnings behind ordinary objects, legendary figures, and even the sayings we use every day; why did Abraham Lincoln once step into the wrestling ring? How do million-dollar birds procreate? What's the story behind a dog that ignited an international conflict? These are the strangest origin tales you've never heard-and won't believe!
- How did a pet pig spring into action to save its owner's life? Which mysterious spirits became the unlikely heroes that turned the tide for a doomed flight? And what shocking move did a carjacker make to rescue a baby trapped in a scorching car? These are the wild, unexpected stories of heroes you'd never see coming.
- When the sun sets, strange things come alive; imagine a full-scale war waged against thousands of invading frogs, an artist who only paints while sleepwalking, and battlefield wounds that literally glow in the dark; these bizarre and unbelievable moments all have one thing in common they happen only when darkness falls.
- From a piece of the International Space Station crashing into a Florida home, to the first chimpanzee blasted into space, to a mind-bending time slip experienced by two women in Versailles, this episode dives into the unbelievable stories that challenge what we think we know about our place in the universe.
- From the kitchen to the battlefield, some machines are just too strange to believe; like an appliance that runs on pup power; or a mousetrap so deadly, you need a permit to own one; how about a submarine car straight out of a Bond movie? Whether brilliant or baffling, these devices push the limits of what you thought possible.
- History is full of miracle cures, far-fetched products, and astonishing feats, but not all of them are legitimate; a miracle snake oil that cures all? A piece of the Brooklyn Bridge for sale? A marathon-winner who crosses the finish line without hardly breaking a sweat? These are the stories of some of history's most spectacular cons, each deception more unbelievable than the last.
- Weapons rank among humanity's most powerful-and wildest-inventions; some unleash mass destruction, while others are downright bizarre; from launching corpses with trebuchets, to turning animals into killing machines, and missiles guided by pigeons, these are the stories behind history's most outrageous weapons.
- The world is full of strange and mind-bending places, but some take the cake; explore an island ruled by deadly predators, a Florida town obsessed with the wildest circus performers, or a mysterious paranormal hotspot that's a magnet for UFOs, strange sightings, and baffling disappearances; these are the weirdest corners of the planet you have to see to believe.
- A brush with death is terrifying enough-but these stories take survival to the extreme; like fending off a black bear while dangling off a cliff; drifting through shark-infested waters with nothing but a pair of rubber boots to stay afloat; just when you think skydiving is the real danger-try crash-landing into a nest of thousands of angry fire ants.
