Fun Facts That Are

Jhonatan Gonzalez was hiking the Narrows at Zion National Park with his family - kids as young as 1 - when the calm river suddenly turned waist-deep and raging, choked with logs and debris. He and his brothers planted themselves in the current and formed a human chain. Strangers on the bank grabbed on. Dozens of hikers, including toddlers, passed hand-to-hand to safety. Everyone made it out.

Deep inside Neptune and Uranus, heat and pressure squeeze carbon from methane into diamonds that sink toward the core. In 2017, scientists at SLAC recreated the conditions and watched diamonds form.

Roy Sullivan, a US park ranger at Shenandoah National Park, was struck by lightning seven times between 1942 and 1977 and survived every one - the most lightning strikes ever survived by a person, per Guinness World Records.

Cleopatra lived closer in time to the 1969 Moon landing than to the building of the Great Pyramid (around 2560 BC). The pyramids were already about 2,500 years old in her lifetime.

In open-label placebo trials, patients told plainly they were taking sugar pills still reported real symptom relief for conditions like IBS, back pain and migraine.

In 1901, sponge divers exploring a 2,000-year-old shipwreck off Greece hauled up a corroded lump of bronze. Decades of scanning revealed what it was: a mechanical computer of around 30 interlocking gears that tracked the Sun, Moon and planets and predicted eclipses. Nothing this complex appears again for more than a thousand years.

Roman concrete has lasted nearly 2,000 years and can self-heal cracks: lime clasts from hot-mixing dissolve and recrystallise when water seeps in. MIT identified the mechanism in 2023.

Socotra broke away from Africa millions of years ago; about a third of its plants exist nowhere else, including the umbrella-shaped dragon blood tree that bleeds red sap.

Wombats are the only animal that makes cube-shaped droppings - about 80 to 100 a night. Varying stiffness along the intestine shapes them, and they stack the cubes to mark territory because cubes do not roll away.

Octopuses have three hearts and blue, copper-based blood. About two-thirds of their neurons sit in their eight arms, which can taste, touch and act semi-independently, and they can edit their own RNA.

Turritopsis dohrnii, when old, starving or injured, can revert its adult cells to a juvenile polyp and start its life over - making it biologically immortal.

A flock of Canada geese knocked out both engines of US Airways Flight 1549 roughly two minutes after takeoff. Captain Chesley Sullenberger had about three and a half minutes to save 155 lives. He landed on the Hudson River - and when NTSB later ran simulations with a realistic 35-second decision delay added, the return to LaGuardia crashed short of the runway. The river was the only choice. Every single person survived.
