Corkscrew roller coasters feature tracks that twist 360 degrees around their axis

Why roller coaster loops are never circular

The beloved looped roller coaster rides used to be shapes as perfect circles and constructed with wood, resulting in wobbly machinery that gave people whiplash. After the invention of steel and further scientific understanding, Six Flags debuted The Great American Revolution—a modern, oval loop with steel that offered a safer and smoother experience.

Modern innovations have allowed rides to simultaneously become more extreme and safer

Several ingenious additions to roller coasters, such as extra wheels, magnetic brakes, and hydraulic system safety bars, have largely reduced discomfort and threats such as broken rides or ejected passengers.

Russia is credited with developing the original roller coaster

Roller coasters are believed to have originated in the 1600s with 70-foot wooden ice slides, typically enjoyed by the upper class. Over the past few centuries, the machinery developed into more daunting designs like the modern gigacoaster, which features a drop of 300 feet or more.

Roller coasters can cost millions of dollars to make, but they often offer a substantial payoff

Over 6,000 roller coasters are in operation around the world as of 2025, with ongoing demand to build more each year. Despite being costly (some theme parks pay upwards of $50M for these rides), their financiers are able to justify the investment when considering the long-term value of a ride that sticks around for decades with daily streams of visitors.

Zero-g rides get their name from the weightless sensation of being turned upside down

Inversions are when riders are flipped upside down on rides. Zero-g rolls involve turning 360 degrees with inversions, resulting in a temporary experience of zero g-force for passengers.

Virtually experience a euthanasia roller coaster

In 2010, Lithuanian artist Julijonas Urbonas came up with a fictional euthanasia coaster to generate conversation about humanely ending life. His idea involved using extreme G-forces on a roller coaster, aiming to give participants feelings of euphoria before death. In reality, the ride would probably be extremely unpleasant.

The Wrights innovated controlled flight along three axes—pitch, roll, and yaw

Gliders studied by the Wrights were unwieldy and unable to be fully controlled by the pilot. Wilbur and Orville invented so-called wing-warping which twisted their surface and allowed for the plane to roll (or turn), all using a device manipulated by the hips.

The quintuple jump in figure skating is feasible, according to physics

As of 2025, many figure skaters feature jumps with four spins in their routines by achieving rotation rates of 400 RPM over 20 inches off the ground. By increasing one's rotation rate to about 430 RPM or jumping closer to three feet off the ground—a height reached by NBA players—five spins are possible.

A fascinating look at why cucumber tendrils coil in opposite directions

The tendrils of cucumber plants coil when they hit a surface, creating a distinct telephone-cord look. Charles Darwin wrote about the mystery in the 1850s, though it wasn't until the 21st century that scientists figured out just how mysterious the coil is: its tendrils coil in opposite directions.

Hurricanes spin due to differences in air and ground speed as they move across Earth

The movement of an object across latitudes causes it to take a curved trajectory because its speed no longer matches that of the ground beneath it. This phenomenon, called the Coriolis effect, explains why hurricanes spin counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

How electrical transformers use coils of conductive wire to change voltage levels

Two sets of wires are wrapped around a magnetic core, each a different number of times. As alternating current flows through one wire, it generates a changing magnetic field that induces an alternating current in the second wire. If the second wire has fewer coils, the voltage steps down—decreases. If the second wire has more coils, the voltage steps up.

Wikiracing involves moving between two articles in the fewest clicks

The quirky pastime has evolved into a competitive event at yearly Wikimedia conferences, highlighting the interconnectedness of human knowledge. Neuroscientific research suggests lateral thinking is a crucial skill found in successful Wikiracers.

Hurricanes, which rely on air consistently spinning in the same direction, cannot cross the equator because air curves in opposite directions north and south of it.

One of the Widow Clicquot’s many innovations was the process of riddling

Riddling involves storing Champagne bottles at an angle and methodically turning them in order to collect any sediment in the neck of the bottle. The technique—which was kept a strict secret—cut down on both time and waste, allowing the House of Clicquot to outsell its competitors for decades until word inevitably leaked and riddling became the standard.

Cultivate your coffee taste with this interactive flavor wheel

Coffee is one of the more complex things humans consume, and taste can vary drastically based on bean genetics, roasting technique, and more. Using this flavor wheel, you can more accurately describe your coffee's aroma by starting from the center and moving outward.

The Koch snowflake has an infinite perimeter enclosing a finite area

Counterintuitively, although it would be impossible to build a fence along the edges of the shape because it would require an infinite amount of materials, this perimeter can be contained in a larger shape with a finite perimeter and limited area. This is equivalent to enclosing an infinitely long spiral that never reaches the center within a circle.

Mid-ocean ridges are underwater volcano systems where tectonic plates diverge

New ocean crust is formed at these ridges as magma rises from Earth’s mantle and fills the space between the spreading plates. The speed of divergence influences ridge shape, with slow spreads forming rugged valleys and fast spreading creating smooth, wide slopes.

Rock 'n' roll began as a hybrid of several American musical styles

Rock ‘n’ roll combined blues, swing, country, and other American musical forms in the late 1940s. From there, it splintered into countless subgenres and is still evolving.

Breaking down 'clinch covers,' a defining characteristic of '80s romance novels

As romance novels became more popular in the 1980s, publishers leaned into the books' steamier content by advertising it on their covers. Eventually, one specific kind of portrait emerged: the clinch cover, which featured a muscly man, usually shirtless, holding a woman against his chest. This episode from 99% Invisible explores the history of the trend and why it's largely disappeared from modern romance novels.
