Microchip

Before microchips, computers relied on glass vacuum tubes that were large, fragile, and too heavy for a spacecraft. To solve this, NASA, during the moon race in the 60s, made a massive bet on a new invention called the integrated circuit, which packed complex electronics onto a tiny sliver of silicon. While these early "microchips" were very expensive and unproven, the Apollo program committed to buying over 60 per cent of all chips made in America. This guaranteed market gave companies like Fairchild Semiconductor, a Californian technology company, the support they needed to perfect the tech and lower the costs. NASA's support as the principal customer for microchips helped the digital revolution happen much sooner than expected. Today, that technology is within almost every electronic device, from the microwave to the laptop.

Smoke Detector

They are among the most important safety tools in our homes, and most people don't know their modern version was shaped for a 1970s space mission. Truth is, the first electric smoke detector was invented in the 1930s by Swiss physicist Walter Jaeger, almost by accident, while working on a gas detection device. Early smoke detectors worked, but they were often too expensive or sensitive for everyday homes.

In the 1970s, NASA teamed up with Honeywell Corporation, a North Carolina-based technology and manufacturing company, to improve the design for Skylab, the first U.S. space station. Astronauts needed an alarm that could detect a real fire without constantly reacting to harmless gases inside the station's tight living quarters. So they added an adjustable sensitivity and long-lasting backup batteries, creating the "nuisance-free" smoke alarm we still use in our homes today.

Cell Phone Camera

In the 1990s, NASA's Jet Propulsion Laboratory needed to shrink cameras down so they could fit on small spacecraft without draining the battery. Engineer Eric Fossum invented the image sensor, which put all the camera's functions onto a single tiny chip , making cameras much smaller and more efficient than ever before.

In 1995, Fossum founded the company Photobit to bring this space-age sensor to the commercial market. Today, this technology allows smartphones to take high-quality photos while staying thin enough to fit almost everywhere, making it the most used camera tech in the world.

Cordless Tools

In the early 1960s, Black & Decker developed the first cordless electric drill for commercial use. NASA later recognized the potential and, in 1965, contracted Black & Decker to adapt and refine this technology for the Apollo program, creating a lightweight, battery-powered drill that could operate in the moon's harsh environment and in zero gravity.

But that wasn't all. To make it work for space, they had to improve a specialized motor and smart software that didn't drain the battery too fas t. By the late 1970s, the Dustbuster, the first cordless vacuum, was created, along with the improved battery-powered tools we still rely on today.

Memory Foam

Have you ever wondered why your mattress is smart enough to remember its original shape? Memory foam is a type of high-density polyurethane foam that softens when heated and under pressure. When you lie down on it, it molds to your body, and when you get up, it slowly returns to its original shape. That's what the "memory" part is about.

NASA developed memory foam in the 1960s to improve seat cushioning and crash protection for airline pilots and passengers, and later adapted it to protect astronauts from "G-forces" during space travel . As it reacted to body heat, the foam softened and molded perfectly to a person's frame, absorbing shock on impact. It took about twenty years to reach the public; the first memory foam mattress didn't hit the market until the early 1990s by companies like Tempur-Pedic and Fagerdala World Foams.

Sneaker Air Cushioning

Ever wondered how Nike Airs were created? The truth is that the bounce in many modern sneakers is actually a product of the space industry. A NASA engineer named Frank Rudy, who worked on the Saturn and Apollo rocket engines, was introduced to a process called blow rubber moulding, used to create sealed, pressurised membranes for aerospace applications. He realized this same process could be used to trap gas inside a shoe sole.

In 1977, he brought this idea to Nike, and this led to the creation of the Nike Air Tailwind in 1978, the first shoe to feature this space-inspired cushioning. Today, air-cushioned soles are a standard, using the same aerospace tech to protect joints in every step.

7

Water Filters

In 1963, NASA faced an important challenge for the Apollo program: keeping drinking water pure for long missions without using heavy chemicals. To solve this, they pioneered a system that used silver ions to kill bacteria and activated carbon to remove pollutants. This allowed astronauts to have clean water stored for weeks.

By the 1970s, NASA shared this technology with the public, leading to the creation of companies like Aquaspace. These days, this same silver-ion and carbon tech is used inside household water pitchers and refrigerator filters to remove contaminants.

8

Scratch-Resistant Lenses

In the 1970s, NASA scientist Ted Wydeven of the Ames Research Center was working on a spacecraft water purification system when he coated a filter with a thin plastic film using an electric discharge of an organic vapor. The result protected the plastic surfaces of aerospace equipment from scratching.

This film made plastic up to ten times more scratch-resistant than earlier materials. In 1983, Foster-Grant licensed the technology and used it to produce scratch-resistant lenses for sunglasses and eyeglasses, introducing space technology to our daily lives.

Ear Thermometer

NASA technology and modern healthcare are surprisingly close. It turns out that the same tech used to measure the heat of distant stars is now in our medicine cabinet . In the 1980s, NASA developed special infrared sensors because scientists evidently couldn't place a physical thermometer on a planet millions of miles away. These sensors worked by "reading" invisible heat energy from a distance.

By 1991, a medical technology company called Diatek teamed up with NASA to bring this space tech into daily medicine. They realized the human eardrum also emits infrared heat, and that could work as a perfect window to measure our body temperature. This partnership resulted in the first handheld ear thermometer, making fever checks much more comfortable and easier.

10

Super Soaker

You probably assumed that the world's most famous water gun was created in a toy lab. It was actually invented in the home workshop of NASA engineer Lonnie Johnson. In 1982, while working on a new heat pump that used water instead of refrigerant, a nozzle he was testing shot a powerful stream across his bathroom.

Johnson realized its toy potential and licensed his "Power Drencher" design to the toy company Larami. It was renamed to the Super Soaker in 1991, and it uses the same air-pressure principles Johnson applied to spacecraft systems.

Construction costs that’d make your wallet faint

Image: Jaime Labra

Back in 1912, the Titanic cost $7.5 million to build, and if you're wondering what that’d be today, it’d be over $400 million. That’s more than some sports stadiums! It took nearly three years to complete and was one of the most extravagant ships ever made.

2

Yes, there were dogs

Image: Yuki Dog

As it turns out, the Titanic wasn’t just for people. At least 12 dogs came along for the ride , lounging in a special first-class kennel. There was even a dog show scheduled for the morning of April 15. Sadly, only three tiny dogs survived, all small enough to sneak onto lifeboats tucked in coats or handbags.

The band really did play on

Image: Parizan Studio

Wallace Hartley, the bandleader, went down in history, and with his violin! His group kept playing as chaos unfolded around them, trying to calm passengers with music, just like the movie portrays. He didn’t make it, but his violin was found intact and later sold at an auction for $1.7 million!

A pocket watch frozen in time

The violin was not the only treasure found. Sidney Sedunary was a young steward whose pocket watch stopped ticking at exactly 1:50 a.m. , just before the ship went under. He was last seen handing out lifejackets to third-class passengers. That same watch, rusted but intact, still tells his story.

A survivor with frostbitten legs and Olympic dreams

Richard Norris Williams spent six hours in icy water, and doctors on the rescue ship wanted to amputate his legs. He refused . And you may think he was crazy to do so, but thank God he did! He went on to win a Wimbledon title and an Olympic gold medal. How crazy is that?

Finding the Titanic by accident

Image: Karl Callwood

In 1985, oceanographer Robert Ballard found the Titanic wreck. But that was just an accident ; he was actually sent by the Navy to look for two lost nuclear submarines and used the Titanic as a cover story.

Dishes still stacked neatly on the ocean floor

When explorers visited the Titanic wreck in 1986, they found plates still stacked like someone had just finished doing the dishes. Turns out, the wooden cabinet they were in rotted away , leaving the china perfectly arranged on the sea floor. It’s as eerie as fascinating, considering the many years that passed.

8

The ship is rusting away

Image: NOAA

And speaking of the amount of time the Titanic has been underwater, we have to say that nature is reclaiming the Titanic bit by bit. A newly discovered bacterium is literally eating the ship. Scientists estimate it could disappear completely in 20 to 30 years. The latest expeditions have already shown evidence that pieces that were previously there are gone. So… the clock's ticking.

No photos of the grand staircase?

Image: Maria Orlova

You’ve probably seen images of the Titanic’s beautiful grand staircase. We’re sorry to disappoint, but they’re not of the Titanic . They’re from her sister ship, the Olympic. No one thought to take a picture of the real deal before the maiden voyage. And they definitely didn’t think of doing it while it happened!

Milton Hershey almost boarded

Image: Janne Simoes

If the name rings a bell, that’s because it’s the same Hershey from the chocolate you love. The man behind Hershey’s chocolate bars almost booked a room on the Titanic . He even wrote a $300 deposit check (big money back then!). But business delayed him, and he skipped the trip. Who do we thank for that?

11

The baker who survived two hours in icy water

Image: Maxim Hopman

Here’s a fascinating fact: Charles Joughin, the Titanic’s chief baker, survived one of the worst parts of the sinking: the freezing Atlantic water. He was reportedly treading water for two hours before rescue. Wanna know how he made it? He had been sipping whiskey to face his fate, and the alcohol in his blood kept him warm enough to survive.

12

The last lunch menu went for a tasty sum

Image: Zoshua Colah

In 2015, a copy of Titanic’s last first-class lunch menu sold for $88,000 . That’s one pricey memento. The menu included grilled mutton chops, chicken à la Maryland, and corned ox tongue. Safe to say lunch on the Titanic wasn’t your average sandwich and chips.

It was almost completely torn down

Did you know that very little of today’s White House interior is actually original? Looking at the building now, it’s hard to imagine that it was once so unstable that it was in danger of collapsing.

By 1948, after decades of heavy use, outdated wiring, poor structural supports, and years of renovations layered over one another, the White House had become unsafe. Floors and walls cracked, and parts of the residence were literally sinking. President Harry S. Truman even joked that the place felt haunted because it made so many strange noises. Rather than abandon it, Truman launched a massive reconstruction project with Congress. Between 1948 and 1952, nearly the entire interior was gutted and rebuilt while the original exterior walls were preserved, giving America a strong and reliable White House.

During WWII, they built an underground bunker

Did you know there’s a fortified bunker hidden beneath the White House? A couple of years before Truman’s famous renovation, another major project was quietly built beneath the presidential residence.

In 1942, during World War II, President Franklin D. Roosevelt ordered the construction of a secure underground shelter to protect government leaders in case Washington, D.C., came under attack. Built quickly and in great secrecy, the bunker was completed within months, though it was luckily never needed during the war. Today, the facility is known as the Presidential Emergency Operations Center, or PEOC, and it was famously used in 2001 by President George W. Bush and again in 2020 by Donald Trump.

It was not originally meant to be white

Can you imagine if it were called "the Gray House"? Today, it’s impossible to picture America’s most famous home as anything other than bright white, but that wasn’t the original idea.

During construction in the 1790s, workers covered the exterior sandstone with a lime-based whitewash to protect it from moisture, cracking, and harsh winter weather. The coating gave the building a pale grayish appearance, not the brilliant white we recognize today. A long-standing myth claims the White House was painted white to hide the burn marks left after British troops set it on fire in 1814, but in reality, the building had already been whitewashed years earlier. Still, after the fire and reconstruction, the white exterior became permanent and eventually inspired the famous name "White House," though for many years people still called it the "President’s House."

10 people have died in the White House

Many people have lived and worked in the White House over the centuries, but, according to the White House Historical Association, only 10 people are officially recorded as having died inside the presidential residence.

Among them were two U.S. presidents. William Henry Harrison died there at age 68 in 1841 after falling seriously ill, likely from contaminated water. Zachary Taylor died at age 65 in 1850 from a severe stomach illness after attending Fourth of July celebrations in extreme heat. Three First Ladies also passed away in the White House: Letitia Tyler in 1842, Caroline Harrison in 1892, and Ellen Axson Wilson in 1914. Other deaths included presidential relatives, aides, and staff members, among them Abraham Lincoln’s son, Willie Lincoln, whose death at the age of 11 in 1862 deeply affected the family and became one of the White House’s most heartbreaking stories.

Presidential whims

Not every White House renovation happened due to war, damage, or urgent repairs. Some changes came simply from the personal tastes and hobbies of the presidents who lived there, and over the years, there have been quite a few memorable ones.

In 1973, Richard Nixon installed a one-lane bowling alley beneath the North Portico. Years later, in 1989, George H. W. Bush added a regulation horseshoe pit near the White House grounds, where he often relaxed and challenged visitors, including Queen Elizabeth II, to games. Then, in 2009, Barack Obama had the South Lawn tennis court modified so it could also be used for basketball, one of his favorite sports.

Jackie Kennedy's furniture

When the Kennedy family entered the White House in 1961, the first lady was disappointed to find that many of the historic rooms had lost much of their original character.

Determined to restore the White House’s history and elegance, Jackie Kennedy famously launched a massive restoration effort. She helped create the White House Fine Arts Committee, brought in historians and curators, and filled the residence with genuine antiques and historical pieces tied to past presidencies. On February 14, 1962, an estimated 46 to 56 million people tuned in to watch the First Lady’s televised tour of the White House, making it one of the most-watched programs of its era. She also supported a congressional act that made many of the White House’s historic furnishings official property of the nation, so future presidents could no longer sell, replace, or discard them.

7

Official name changes

As we mentioned, the building was not always white, and therefore was not always officially called the White House. For much of the 19th century, Americans usually referred to it as the "Executive Mansion" or the "President’s House." Even after its famous white exterior made the nickname popular, it still was not the building’s official name.

That finally changed in 1901, when Theodore Roosevelt began printing "The White House" on presidential stationery. According to official sources, Teddy Roosevelt preferred this name because it clearly separated the president’s residence from the many state "executive mansions" used by governors across the country.

8

It was once America's largest house

There is one thing about the White House that no one can deny: it has always been huge, even in its early days.

When the White House was first occupied in 1800, it already contained more than 100 rooms spread across three floors, making it one of the grandest homes in the United States at the time. In a time when most Americans lived in modest houses or farms, the presidential residence was seen as a palace. Many historians even consider it the largest private residence in the country during its early years. Today, the White House covers about 55,000 square feet, though modern private buildings, like the Biltmore Estate in North Carolina, are now far larger.

9

President Benjamin Harrison’s fear

Among the many changes the White House has undergone over the years, few were as revolutionary as the arrival of electricity.

For nearly a century after it was built, the presidential residence relied on candles, oil lamps, and gas lighting. That finally changed in 1891, when electricity was installed during the presidency of Benjamin Harrison. But, like many families in that era, the Harrisons were not exactly thrilled by this modern invention. According to White House stories passed down over the years, President Harrison and First Lady Caroline Harrison were so nervous about the possibility of electric shock that they rarely touched the light switches themselves. Instead, they often asked the house staff to turn the lights on and off for them.

10

Hillary Clinton’s special gift

Of course, Jackie Kennedy wasn’t the only First Lady to leave her mark on the White House. Hillary Clinton added her own personal touch as well, this time as a gift for her husband.

In 1996, Hillary Clinton transformed a little-used room on the White House’s third floor into a private music room for President Bill Clinton. The gift came during the year of Bill Clinton’s 50th birthday and reflected one of his best-known passions: music. Complete with space for listening to records and playing his famous saxophone, the room gave the president a quiet retreat inside the White House.
