On March 31, 1918, Americans across the country set their clocks forward by one hour, marking the first nationwide implementation of Daylight Savings Time in the United States. This change came as part of the Standard Time Act, which Congress had passed earlier that month. The country was in the midst of World War I, and the government hoped that extending evening daylight would help conserve fuel needed for the war effort.

The idea wasn't entirely new - Benjamin Franklin had jokingly suggested something similar in 1784, and several European countries had already adopted the practice during the war. Germany had been the first to implement it in 1916, and Britain followed soon after. The United States was actually catching up to a growing international trend designed to maximize productivity and save resources during wartime.

Many Americans found the change confusing at first. Newspapers printed detailed instructions explaining when and how to adjust clocks, and there was considerable debate about the benefits. Farmers were particularly opposed to the shift, as their work depended on the sun rather than the clock, and they now had to wait an extra hour for morning dew to dry before they could harvest certain crops.

After the war ended, Congress repealed the national Daylight Savings Time law in 1919, though some cities like New York continued the practice locally. It wouldn't return nationally until World War II, when "War Time" was implemented year-round. The familiar pattern of "spring forward, fall back" that Americans know today wasn't standardized until the Uniform Time Act of 1966, which established a consistent national approach to time-keeping that still generates debate over a century after its first implementation.

On March 31, 1932, in the midst of the Great Depression, Henry Ford introduced an innovation that would change the automotive industry - the Ford V-8 engine. This was the first time an affordable, mass-produced car featured a powerful eight-cylinder engine. Previously, such engines had been available only in expensive luxury automobiles that ordinary Americans couldn't afford.

Ford's engineers had worked in secret for over a year to develop this engine, overcoming numerous technical challenges. The breakthrough came when they figured out how to cast the engine block as a single piece, making it possible to produce these complex engines efficiently and economically. This manufacturing innovation was just as important as the engine design itself, demonstrating Ford's continued commitment to making advanced technology accessible to average consumers.

The timing of this release surprised many people in the industry. With the economy in shambles and car sales plummeting, most folks suggested companies should focus on cheaper, more basic vehicles. Ford took the opposite approach, betting that offering more power at an affordable price would attract buyers even in tough economic times. The gamble paid off - the new Ford V-8 sold well despite the Depression and helped cement Ford's reputation for innovation.

The V-8 engine quickly became synonymous with American automotive culture. Its smooth power delivery and distinctive rumble made it popular with everyone from family drivers to police departments to bootleggers outrunning the law. The 1932 Ford with its V-8 engine later became a favorite among hot rodders and car enthusiasts, remaining an iconic vehicle in automotive history. What began as a bold depression-era gamble evolved into a defining feature of American cars for decades to come.

Calvin Coolidge Electric Horse🐴
President Calvin Coolidge wasn’t known for excitement—his nickname was literally “Silent Cal”—but he did have one curious hobby: riding an electric horse for exercise. Yep, inside the White House, Coolidge had a mechanical horse contraption designed to simulate real riding. He’d mount up and “gallop” in place to stay fit, even reportedly using it multiple times a day in a suit and tie. Why not just ride a real horse? Easier on the schedule—and no cleanup required.

Japans Black Teeth Practice🦷
In ancient Japan, especially during the Heian period (794–1185), black teeth weren’t a dental disaster—they were a beauty statement. The practice, called ohaguro, involved dyeing teeth black using a mixture of iron filings, vinegar, and sometimes tea. Aristocrats, especially women, did it to show elegance, maturity, and high status. It wasn’t just about looks—it also helped preserve teeth, acting like a primitive sealant. Eventually, samurai and even some married women adopted the look too. So back then, a shiny white smile? Totally commoner. In courtly Japan, pitch-black teeth meant class.

Dolphin Trainer Love Story🐬
In the 1970s, as part of a NASA-funded experiment, researchers tried to teach a dolphin named Peter to speak English. Yes, actual spoken English. The setup was... unusual. A young trainer named Margaret Howe Lovatt lived with Peter in a flooded house for weeks, helping him mimic words like “hello” and “ball.” Spoiler: Peter never learned English—but he did develop a deep, awkward crush on Margaret. Peter would get very attached, even jealous, and displayed romantic (and at times very inappropriate) behavior, which the researchers awkwardly tolerated in the name of science. The experiment eventually ended, but the story remains one of the strangest chapters in animal research history—equal parts fascinating, cringey, and very 1970s.

Arsenic Makeup💄
In the 1800s, pale skin was the beauty standard—so some folks turned to a horrifying solution: arsenic-laced face powder. The powder promised a “fresh, porcelain glow”, but in reality, it slowly poisoned the user. Symptoms included hair loss, skin sores, organ damage, and, well... death. But hey, at least they looked good while fading away, right? There were even arsenic wafers and tonics sold to “improve complexion” from the inside out. Spoiler: that didn’t end well either. So yeah—beauty might be pain, but in the 1800s, it was also toxic.
