Modern life depends on a surprising number of ancient or overlooked inventions. From common kitchen tools to office supplies, many everyday items have roots buried deep in history. Some were invented by accident, others by necessity—but most have a backstory you’ve likely never heard. Here are 10 objects you use regularly that carry a legacy most people forget.

1

Scissors

Invented in ancient Egypt around 1500 BCE, the earliest scissors were made of bronze and operated with a spring mechanism.

The modern pivoted scissors, as we know them today, appeared in Rome around 100 CE. Leonardo da Vinci even improved their design while using them for fine arts and tailoring.

Paperclip

The paperclip was never patented for its most iconic shape—the Gem clip—because it was already in commercial use before its design could be protected.

Invented in the late 19th century, the paperclip's rise paralleled the spread of mass bureaucracy. During WWII, Norwegians wore them as symbols of resistance against the Nazis, defying a ban on national symbols.

Toothbrush

The first bristle toothbrush originated in China during the 15th century, featuring hog hair bristles set into bamboo or bone handles.

Mass production in the West didn’t happen until 1780, when Englishman William Addis created one in prison, of all places. Nylon bristles only appeared in 1938, giving us the modern version still used today.

4

Zipper

The zipper began as a "clasp locker" in 1893, designed by Whitcomb Judson to fasten shoes.

It wasn't until 1913 that Gideon Sundback refined the mechanism into what resembles the zipper we use today. It caught on after being used in military gear and was later popularized in fashion by designers like Elsa Schiaparelli.

5

Fork

Forks were once considered scandalous. Introduced to Europe by Byzantine royalty in the 11th century, they were mocked for being "effeminate."

Consequently, their adoption was slow. By the 17th century, forks became standard at aristocratic tables in Italy and France, but didn’t become common in England or America until the 18th century.

6

Can Opener

Shockingly, canned food came before the can opener—and by decades! To make matters worse, early cans were so thick they had to be opened with chisels or bayonets.

Ezra Warner patented the first can opener in 1858, and a rotating-wheel design followed in 1870. The modern safety can opener with a side-cutting wheel wasn’t patented until 1956.

7

Soap

Ancient Babylonians made soap around 2800 BCE from water, alkali, and cassia oil. The word "soap" comes from Mount Sapo, where Roman legend says animal fat and ash ran into the Tiber River.

Despite its ancient origins, soap didn’t become widely used for personal hygiene until the 19th century, when cholera outbreaks underscored the need for better sanitation.

Post-it Notes

Created by accident, the adhesive used in Post-it Notes was originally a failed attempt to make a super-strong glue.

In 1974, Art Fry used the weak adhesive to mark pages in his hymnal. Realizing its potential, 3M released the product nationwide in 1980, and it became a staple in offices and schools worldwide.

9

Velcro

Swiss engineer George de Mestral invented Velcro in 1941 after noticing burrs sticking to his dog’s fur during a hike.

It took over a decade to perfect the manufacturing process. NASA popularized Velcro in the 1960s for use in zero-gravity environments, boosting its civilian use.

Shopping Cart

Sylvan Goldman, owner of a grocery chain, invented the shopping cart in 1937 to help customers buy more.

Customers initially resisted using them, so Goldman hired actors to push them around stores to normalize the concept. Today, over 25 million carts are used in the U.S. alone.

Beyond humanity: 10 smartest animals in the world


Published on September 8, 2025

When it comes to intelligence, humans are not alone on the planet. Far from it—many species exhibit incredible problem-solving skills, complex social behaviors, and even the ability to communicate with us. While their abilities differ from those of humans, they often excel in areas where humans are at a disadvantage. From the ocean depths to the skies, these 10 animals have earned their place among the planet’s brightest.

1

Dolphins

Dolphins are not just adorable—they're renowned for their intelligence and communication skills. Using distinct sounds, they share information about food, danger, and more.

They understand human gestures, perform complex tricks, and even recognize themselves in mirrors—a trait shared with humans, some great apes, and elephants.

2

Chimpanzees

Chimpanzees are often regarded as humans' closest relatives in the animal kingdom. They can use tools to gather food, build shelter, and even hunt.

Remarkably, chimpanzees can learn to communicate with humans using sign language and are capable of understanding symbolic meaning, making them one of the smartest non-human animals.

3

Elephants

Elephants display an extraordinary level of empathy and self-awareness. Known for their exceptional ability to recall places, individuals, and events across decades, they possess large brains with highly developed regions linked to emotions and memory.

Moreover, they mourn deceased companions and assist injured or sick elephants—clear signs of advanced cognition.

4

Crows

Crows exhibit problem-solving skills on par with some primates. They can use tools, create tools, and solve complex puzzles that involve multiple steps.

In one famous experiment, a crow used a series of tools to extract food from a tube, showing their ability to plan ahead. Crows also have excellent memories and can recognize individual human faces.

5

Octopuses

Octopuses are escape artists. Famous for escaping closed tanks, unscrewing jars from the inside, and easily navigating complex mazes, these genius invertebrates challenge what we understand as non-human intelligence.

Their large brains and complex nervous systems enable impressive spatial learning and navigation, helping them thrive as nimble predators.

6

Orcas

Also known as killer whales, orcas are highly intelligent animals known for their complex cooperative hunting techniques. They work together to catch prey, using coordinated strategies that can even involve creating waves to knock seals off ice chunks.

Their communication is incredibly sophisticated, and they even have regional dialects.

7

African Grey Parrots

African Grey Parrots are famous for their ability to mimic human speech, but their intelligence goes far beyond vocal mimicry. They can associate words with meanings, use them in context, and even form simple sentences.

In research studies, African Greys have even demonstrated an understanding of abstract concepts such as shape, color, and number.

8

Ants

While isolated individuals are not particularly intelligent, ants have a unique form of collective intelligence that allows entire colonies to perform highly complex tasks way beyond the capability of a single ant.

Their intricate nests and structures are proof of this, with some species even practicing a form of farming by cultivating fungi.

9

Pigs

Pigs are often overlooked in discussions of intelligence, but they are actually one of the smartest animals. They have demonstrated the ability to learn and perform tasks that require reasoning and memory.

Even more, in some studies pigs have been shown to outperform dogs in cognitive tests, indicating their high level of problem-solving abilities.

10

Squid

Squids, particularly the giant and Humboldt varieties, are highly intelligent creatures. They solve puzzles, navigate mazes, and communicate with others using changes in skin color and patterns.

Some squid species show remarkable learning flexibility, even mimicking the behavior of other animals to escape or deter predators.
