One of the most useful things to have around is, without a doubt, duct tape. This product can help fix an endless number of everyday problems in virtually any environment.

This adhesive tape was invented during World War II by a division of Johnson & Johnson called Revolite. It was initially used to seal ammunition cases because of its water-resistant properties.

The GPS technology we all use daily on our smartphones to navigate from point A to point B was originally developed by the U.S. military. It was designed to track the position of military units and help them find their way efficiently across any terrain —much like how we use it today for civilian purposes.

Internet

Few technologies have become such a big part of our lives in just a couple of decades as the Internet. Its origins trace back to the 1970s, when the Defense Advanced Research Projects Agency (DARPA) created an interconnected network linking military centers to enable resource sharing.

The connection of commercial networks and enterprises by the early 1990s, along with the advent of the World Wide Web, marked the beginning of the transition to the modern Internet.

From children’s toys to invaluable communication devices used in critical situations, walkie-talkies are a common fixture in modern life. Their development during World War II has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski, and engineering teams at Motorola.

Initially used by infantry, similar designs were created for field artillery and tank units. After the war, walkie-talkies spread to public safety and eventually commercial use.

Microwave oven

Believe it or not, microwave cooking was accidentally discovered during a military-related project just after World War II.

In 1946, Percy Spencer, a scientist working on a magnetron at Raytheon, noticed that a peanut cluster candy bar in his pocket had melted from the magnetron’s microwave radiation. Curious to experiment further, he brought in some kernels of corn and made the first-ever microwave popcorn—leading to the invention of the microwave oven.

Super glue

In 1942, a research chemist working for a defense contractor was developing a high-precision targeting sight for weapons. Although the project didn’t produce the expected results, the resulting product was incredibly sticky , leading to the creation of the now-famous Super Glue.

Aviator sunglasses

Aviator sunglasses were developed in the 1930s as a lighter alternative to the bulky goggles worn by pilots during the early years of aviation. Those goggles were heavy, uncomfortable to wear, and prone to fogging up mid-flight.

Colonel John Macready of the U.S. Army Air Corps helped develop the first set of aviator sunglasses, which became known as Ray-Bans—named for their purpose: banning the sun’s rays from a pilot’s eyes.

Packaged salad mixes

The bags of packaged salad mixes found at any local supermarket use "modified atmosphere packaging" to delay ripening and spoilage.

This technology was developed in the 1960s through a collaboration between Whirlpool Corp. and the U.S. Navy to send fresh lettuce and celery to troops in Vietnam .

Bug spray

The active ingredient in most insect repellents, known as DEET, was developed by the U.S. Army in 1946 for use by military personnel operating in insect-infested areas . The product’s success led to its commercial release.

Disposable sanitary pads

During World War I, Kimberly-Clark invented Cellucotton, a wood pulp–based material designed to be more absorbent and cost-effective for use in bandages.

After the war, the company discovered that Army nurses had repurposed Cellucotton as sanitary napkins , which inspired the creation of Kotex—the first disposable sanitary pads.

Frozen juice concentrate

In 1942, USDA scientists developed frozen concentrated orange juice during World War II to help provide soldiers with sufficient Vitamin C . Although it was never distributed to the military, the product was later introduced to consumers by Minute Maid.

WD-40

WD-40, now a common household product, was originally developed in 1953 to prevent rust and corrosion on the outer shell of the Atlas missile . Created by the Rocket Chemical Company, the name WD-40 stands for "water displacement," with the "40" representing the number of attempts it took to perfect the formula.

A mountaintop with a maintenance plan

Each year, around two million visitors make their way to see the monument. But keeping the presidential faces looking sharp takes serious work. Park Service staff actually rappel down the mountain to inspect for cracks. They use silicone sealant to block out moisture and keep the granite from breaking apart in the cold. This isn’t a quick job, it’s a regular, careful operation. The mountain's top sits 5,725 feet above sea level, so it’s not for the faint of heart.

One historian’s tourism dream

Image: Engin Yapici

Back in 1923, South Dakota historian Doane Robinson had an idea to attract visitors to the Black Hills. Now, what was his original plan? Carve Western legends like Buffalo Bill and Native American leaders into the rock. The vision then shifted to feature US presidents for broader national appeal.

President Calvin Coolidge helped land the funding, even during tough economic times. The carving began in 1927 and stretched on until 1941. Sculptor Gutzon Borglum died before finishing, and his son Lincoln carried the torch to completion.

Four presidents, four chapters

Image: Jeromey Balderrama

Each face on the mountain stands for a key period in our nation’s story. Can you imagine what they are?

Washington symbolizes the birth of the country, while Jefferson represents growth and expansion. Lincoln stands for unity and the preservation of the nation during the Civil War. Roosevelt brought development and the rise of the US on the world stage. Together, they tell a chronological story in stone. The idea was to highlight leadership through the ages, not just popular figures.

A presidential switch

Image: Andrew Ling

Originally, Thomas Jefferson was supposed to be on Washington’s left. But during the carving, the rock proved too unstable. So they scrapped the partially finished face and started over, this time on the right side.

It was a major do-over that cost time and money, a lot of it! But ultimately, it worked out for the best, structurally speaking. Today, most visitors never realize Jefferson had a false start.

Dynamite and a dream

Image: Takefreebies

It’s easy to forget that Mount Rushmore wasn’t sculpted with tiny chisels: It was blasted into shape. Most of the work was done with dynamite, followed by finer detailing with jackhammers and drills.

From 1927 to 1941, about 400 workers shaped the mountain. Amazingly, no lives were lost during the entire project. Many of the workers were former miners, used to rough terrain and heavy tools. It wasn’t easy, but it was efficient.

The presidents were supposed to have torsos

Image: Thomas Fields

The original vision for the monument wasn’t just heads, it included bodies from the waist up! Imagine that! Like many grand ideas, it ran into budget troubles. Funding dried up, and with time running out, the project was scaled back.

What we see today is actually an unfinished version of Borglum’s full plan. Still, the heads alone have become iconic. Imagine how much more impressive it would’ve been with shoulders and coats.

Secrets behind Lincoln’s head

Image: Rosanne Rapata

There’s a hidden room carved into the mountain, did you know that? Called the Hall of Records, it was Borglum’s idea to store important American documents and artifacts.

While the grand plans for a museum inside the mountain were never fully realized, a titanium vault was placed there. It contains copies of key US documents, including the Constitution and the Declaration of Independence. Located behind Lincoln’s head, it’s not open to the public. Still, it adds an air of mystery to the site. It makes you wanna visit, right?

Step off the beaten path

Most visitors snap their photos from the Grand View Terrace, and it’s lovely. But for those willing to take a short walk, the President’s Trail offers even better views.

This loop takes you closer to the monument and into nature. You might spot local wildlife like mountain goats or deer along the way. The trail includes about 422 stairs, so make sure you’re wearing comfy shoes. It’s a quieter, more personal way to experience the monument.

Entablature

Image: Tommy Bond

Gutzon Borglum didn’t just want Mount Rushmore to be a visual tribute, he wanted it to tell the story of America, too. His idea was to chisel a brief summary history, covering events from 1776 to 1906, right into the rock face.

This massive engraving, called "Entablature," was to be etched into an 80-by-120-foot depiction of the Louisiana Purchase. President Calvin Coolidge even agreed to write it, but when Borglum edited Coolidge’s draft without permission, the president was so annoyed he refused to try again. Despite the grand vision, the project was eventually scrapped, partly because the lettering wouldn’t have been visible from a distance, and partly because the budget ran dry.

Don’t expect a fifth face anytime soon

Over the years, people have suggested adding more figures to the mountain. Names like Susan B. Anthony, FDR, JFK, Reagan, Obama, and Trump have all come up. But the National Park Service has said a firm "no." Structurally, there’s just no safe place to add another carving. Plus, the monument is considered complete in its message. So, while the debate pops up now and then, don’t hold your breath. The original four are here to stay.

Blockbuster

During the 1980s and 1990s, Friday night often meant one thing for American families: a trip to Blockbuster. Browsing the aisles for a movie, debating what to watch, and grabbing popcorn at the counter became a weekly routine. But nothing lasts forever.

Born in 1985, Blockbuster conquered the massive home-video market with thousands of stores by the late 1990s and early 2000s, catering to families with at-home VCRs. Then technology changed everything. First came DVD-by-mail services like Netflix, followed by streaming, which left Blockbuster struggling. Late fees and inconvenience only pushed more customers away. The company filed for bankruptcy in 2010. Today, just one official store remains in Bend, Oregon, where visitors still stop by for a dose of the video-store era.

2

Kodak

Back in the day, almost every vacation, birthday, wedding, or holiday gathering seemed to include a Kodak camera, or at least a roll of Kodak film. Founded in 1881, Kodak helped keep the moments that filled family photo albums for generations.

From the 1960s through the 1990s, Kodak dominated the world of film and photography. But that success also made the company slow to accept that technology was changing. Ironically, Kodak helped invent one of the first digital cameras in 1975, yet it hesitated to embrace the future. By the 1990s and 2000s, digital cameras (and later camera phones) quickly replaced traditional film. In 2012, the company declared bankruptcy.

3

Pan Am

Long before flying became an everyday experience, Pan American World Airways, better known as Pan Am, was already carrying Americans across the world. It was founded in 1927, and during the 1960s and 1970s, the airline became a symbol of glamorous air travel.

Its famous blue globe logo was instantly recognizable, even to those who rarely flew. But by the late 1970s, rising competition, fuel costs, and financial troubles began weakening the company. After years of mounting losses and debt, Pan Am shut down in 1991. Even so, its fame was such that even today, more than 30 years later, we still remember it.

4

Woolworth’s

Before Woolworth's made the "five-and-dime" famous, shopping in America looked very different. For decades, Americans visited Woolworth’s for everything from toys and school supplies to household goods and everyday essentials. By the 1960s, the brand had become a familiar part of American life.

Created in 1879 by Frank Winfield Woolworth, the chain grew into one of the country’s largest retailers. But in the 1970s, malls and discount giants like Walmart changed the way Americans shopped, and Woolworth struggled to keep up. By the 1980s, the iconic chain was slowly disappearing. Most stores closed during the 1990s, and the Woolworth retail chain officially ended in 1997.

5

Circuit City

Testing giant stereo systems, browsing rows of CDs and video games, and shopping for the newest TV were all part of the experience at Circuit City, once one of America’s biggest electronics chains.

Founded in 1949 by Samuel S. Wurtzel in Richmond, Virginia, as "Wards Company," the retailer adopted the Circuit City name in 1984. During the 1980s, 1990s, and early 2000s, it became the go-to place for Americans buying a TV, stereo, computer, or any electronic device. But like many companies on this list, Circuit City struggled as shopping habits changed and online stores became more convenient. A controversial 2007 decision to lay off thousands of experienced employees further hurt the company’s reputation. Circuit City couldn’t survive mounting losses and closed all remaining stores in 2009.

6

Borders

Remember Borders? Born in 1971, its huge stores, filled with books, music, magazines, and cozy reading spaces, invited customers to spend entire afternoons there.

During the 1990s and early 2000s, the rise of large shopping malls actually helped Borders thrive, turning its bookstores into popular destinations inside malls across the US. But eventually, the company ran into a challenge it couldn’t overcome: online shopping and digital reading. Competitors like Amazon surged ahead, while Borders struggled to adapt and made costly business decisions, including outsourcing its online sales to Amazon for years. The company collapsed financially in 2011 and soon closed all remaining stores.

7

Bugle Boy

In the late 1980s and early 1990s, teenage fashion became almost synonymous with Bugle Boy. Famous across the country for its casual jeans and memorable TV commercials, the brand became a major part of American mall culture and was sold in department stores nationwide.

But fashion never stands still, and brands have to constantly adapt to survive. By the late 1990s, newer youth-oriented labels had taken over with fresh styles that quickly made Bugle Boy seem outdated. Sales began to fall, and after years of struggling to keep up with changing trends, the company closed its stores in 2001.

8

Howard Johnson’s restaurants

During the 1960s and 1970s, a stop at Howard Johnson's was part of the classic American road-trip experience for many families, and that was no accident.

Founded in 1925 in Quincy, Massachusetts, the famous orange-roofed chain reached its peak when America’s expanding highways and booming car culture made roadside travel more popular than ever. But by the late 1970s and early 1980s, the growing popularity of fast-food chains like McDonald's began changing the way Americans ate on the road. Drivers increasingly wanted meals that were faster, cheaper, and more standardized, while interstate highways also redirected traffic away from many older roadside locations. Unlike some other brands on this list, Howard Johnson’s faded away slowly over the decades. The last restaurant finally closed in 2022.

9

Burger Chef

In 1958, a name emerged as one of the pioneers of America’s growing fast-food industry: Burger Chef. By the late 1960s, the chain had more than 1,000 locations across the country and had become one of McDonald's’s biggest competitors.

Long before Happy Meals became famous, Burger Chef helped popularize the idea of marketing meals directly to children with toys and themed publicity. But during the fast-food wars of the 1970s, competition became fiercer than ever. While McDonald’s and Burger King expanded by leaps and bounds, Burger Chef struggled with financial problems and changing consumer tastes. In 1982, the company was sold to Hardee's, which gradually converted most Burger Chef locations into Hardee’s restaurants.

10

Sports Authority

Throughout the 1990s and 2000s, many Americans looking for running shoes, gym shorts, and sports gear headed straight to Sports Authority.

Known for its huge stores packed with athletic apparel, exercise equipment, bicycles, camping gear, and team sports products, Sports Authority became the ideal shopping destination for families and athletes across the US. But as online shopping rapidly changed retail in the 2000s, the company struggled to adapt. Heavy debt from expansion efforts and a slow shift to e-commerce eventually caught up with the chain. Sports Authority declared bankruptcy in 2016 and closed all remaining stores later that year.
