Sweet Disaster
In 1919, a 25-foot wave of molasses tore through Boston at 35 mph and killed 21 people.

Not So Well
In early 1991, retreating Iraqi forces set fire to Kuwaiti oil wells. Estimates of the number range from 605 to 732, and the U.S. government counted 610 burning out of 752 damaged wells. At their peak, the fires burned an estimated 4-6 million barrels of oil a day. Firefighting crews from 28 countries began work in April, and the last well was capped on November 6, 1991. Unburned oil formed lakes, estimated at more than 100 to about 300, and the soot and gases degraded regional air quality. Hardened 'tarcrete' crusts and oil-soaked soil left contamination that persisted for decades.
DID YOUKNOW?Dead PoolsDD-049
Dead Pools
Brine pools are lakes on the seafloor: pockets of brine so dense they don't mix with the seawater above, complete with shorelines and even waterfalls. They form where seawater dissolves salt deposits buried under the seabed, such as the layers left when the ancient Gulf of Mexico evaporated, or the evaporites of the Red Sea rift. The best-known example, the Gulf of Mexico's 'Jacuzzi of Despair', lies about 1,000 m down and is about 30 m around. Its brine runs 80 to 110 psu (normal seawater is about 35). It's warm, nearly oxygen-free and charged with methane and hydrogen sulfide. Crabs, isopods and fish that wander in die, and their bodies are preserved along its rim.
DID YOUKNOW?Coffin HomesDD-046
Coffin Homes
Hong Kong's high housing costs have pushed about 220,000 people into roughly 110,000 subdivided units (SDUs). The median SDU in the 2021 census was 11 m², about 6 m² per person. At the extreme are 'coffin' cubicles: wooden, bed-sized compartments in partitioned flats, with a lockable door and little else. They're too low to stand in, and residents share kitchens and toilets. Per square foot, these tiny spaces rent for more than private flats. Hong Kong has regulated 'cage home' bedspace apartments since 1994. A new Basic Housing Units Ordinance, in force from March 1, 2026, sets minimum standards for subdivided flats (at least 8 m², a window and a toilet), but it doesn't cover bedspace or coffin-cubicle housing.
DID YOUKNOW?ForeverestDD-063
Foreverest
More than 300 people have died in the Everest region in a century of climbing, and more than 200 bodies are thought to remain on the mountain. Above about 8,000 m, the so-called death zone, the air holds roughly a third of the oxygen at sea level, and summit temperatures average about -36 °C in January. Bringing someone down from there takes a large team, bottled oxygen and a short weather window, so many of the dead have stayed where they fell. Since 2019, Nepal-funded clean-up campaigns have started to bring some of them home: in 2024 a team of soldiers and Sherpa climbers recovered four bodies and a skeleton.
DID YOUKNOW?ImploderDD-593
Imploder
The human body is mostly water, and water barely compresses. Divers survive great depths because the pressure on them rises gradually and evenly. The weak points are air-filled spaces such as the lungs, middle ears, sinuses and bowel, where gas can be squeezed or forced to expand, a kind of injury called barotrauma. Explosions cause harm in a related way. Blast injury medicine classes the pressure wave itself as primary blast injury, and gas-filled organs, especially the lungs, ears and gut, are the most vulnerable. Underwater, a blast wave travels farther and faster than in air, so it is more dangerous at a given distance. Deep-sea pressure is immense: it rises by about one atmosphere for every 10 meters of seawater, so at the roughly 3,800-meter depth of the Titanic wreck it is about 380 atmospheres, or around 5,500 psi. If a pressure hull fails at that depth, the surrounding water rushes in within milliseconds. That happened to the submersible Titan on June 18, 2023, killing all five people aboard. The US Coast Guard's Marine Board of Investigation reported on August 5, 2025, that the disaster was preventable and blamed mainly OceanGate's design, testing and safety practices. The footage is a stylized CGI figure made of red beads breaking apart, not real injury footage.
DID YOUKNOW?Death FoamDD-043
Death Foam
When highly pathogenic avian influenza or virulent Newcastle disease hits a commercial flock, U.S. policy aims to kill the infected birds on the farm within 24 to 48 hours to stop the virus spreading. Water-based foam was developed for this after the 2004 Delmarva bird flu outbreak, and USDA and the AVMA gave it conditional approval in 2006. Firefighting-style foam is spread over floor-reared birds (broilers, turkeys, ducks) until it blocks their airways, causing physical hypoxia. In trials it killed broilers about as fast as CO2 or faster, with far fewer workers exposed to the virus. The AVMA has never classed it as euthanasia. In its 2026 depopulation guidelines, water-based foam is Tier 2, 'permitted in constrained circumstances', ranked below whole-house gassing and nitrogen-filled high-expansion foam.
DID YOUKNOW?NUCLEAR DISASTERDD-297
NUCLEAR DISASTER
On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Plant exploded and burned, in the Soviet Union's Ukrainian SSR, now The Ukraine. During the accident, molten fuel, cladding, concrete and sand mixed into a lava-like material called corium that flowed into rooms beneath the reactor. The best-known mass, the Elephant's Foot, was found in December 1986 in a maintenance corridor below the reactor's remains. Measurements then put its surface at roughly 8,000 to 10,000 roentgens per hour, enough to deliver a 50/50 lethal dose in a matter of minutes. Its radioactivity has fallen a great deal since, but it remains hazardous, and the site sits inside the New Safe Confinement arch completed in 2016. The footage shows photos from inside the plant and the corium mass.
DID YOUKNOW?Be Not AfraidDD-261
Be Not Afraid
The Book of Ezekiel in the Hebrew Bible describes a vision of four living creatures, later identified as cherubim. Each has four faces, of a man, a lion, an ox and an eagle, and four wings. Beside each is a wheel 'within a wheel' whose rims are full of eyes, and the wheels move with the creatures. In Christian and Jewish tradition these wheels became associated with the ophanim. The phrase 'Be not afraid', often said by angels in the Bible, is popular in modern 'biblically accurate angel' memes based on these descriptions. The footage shows digital renderings of eye-covered rings and winged figures, with the presenter.
DID YOUKNOW?JackDD-108
Jack
Jack the Ripper is the name given to an unidentified serial killer active in and around the Whitechapel district of London in 1888. Five victims, Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes and Mary Jane Kelly, are known as the 'canonical five'; they were killed between 31 August and 9 November 1888. Police investigated eleven Whitechapel murders between 1888 and 1891, but not all are linked to the same killer. Several canonical victims had organs removed, which led some at the time to suggest the killer had anatomical knowledge. The killer was never identified, and many suspects have been proposed since. The footage shows dark AI-style renderings of Victorian London and a figure in a top hat.
