8 Things Invented or Discovered by Accident (1)

We tend to hold inventors in high esteem, but often their discoveries were the result of an accident or a twist of fate. This is true of many everyday items, including the following eight surprise inventions. Let's take a look at the unusual stories behind them.



  1. Corn Flakes
  2. Microwave Ovens
  3. Silly Putty
  4. Post-it Notes
  5. Saccharin
  6. Slinky
  7. Viagra
  8. Bubble Wrap

8. Corn Flakes

In the late 19th century, Dr. John Harvey Kellogg was the superintendent of Michigan's Battle Creek Sanitarium, a world-famous medical spa and grand hotel. He and his brother, W.K. (Will Keith) Kellogg, were also Seventh-day Adventists who believed in vegetarianism. The two were searching for wholesome foods to feed their clients, and especially ones that encouraged a healthy digestive system, as Dr. Kellogg saw a lot of patients with intestinal distress.

Although exact details of the cereal's invention remain disputed, we do know this: One day a batch of wheat-based cereal dough was left out and fermented. Rather than throw it away, the brothers sent it through rollers, hoping to make long sheets of dough. These sheets produced perfect flakes, which they toasted and served to their clients. The toasted flakes were a big hit, so the brothers patented them under the name Granose.


Over the years, W.K. experimented with other grains for use in the cereal, settling on corn, which produced crispier flakes. Eventually W.K. bought the rights to the cereal recipe and, in 1906, founded the Battle Creek Toasted Corn Flake Company, which began producing Kellogg's Corn Flakes.

When W.K.'s company became wildly successful, John got jealous and began making his own competing cereal. The two ended up suing one another. W.K. won in the end, but the brothers remained estranged until their deaths.

7. Microwave Ovens

In 1945, Percy Spencer was experimenting with a new, high-powered vacuum tube called a magnetron while doing research for the Raytheon Corporation. One day the American engineer noticed that when he was near the magnetrons, a peanut-cluster candy bar in his pocket began to melt. Intrigued, he put some popcorn, and then an egg, near the magnetrons. Both cooked within seconds.

Spencer and Raytheon immediately saw the potential in this revolutionary process, which they patented and installed in a kitchen appliance they dubbed the RadaRange. In 1947, Raytheon put the RadaRange on the market. The bulky appliance weighed 750 pounds (340 kilograms), was 5-1/2 feet tall (1.7 meters) and cost about $5,000 — or $62,500 in 2022 dollars.

Not surprisingly, the RadaRange wasn't popular at first, due to its size, price and that fact that it was a strange, new technology. In fact, the RadaRange was considered Raytheon's biggest failure. But by 1975, the product had evolved into a compact, countertop appliance that was much less expensive. That year, microwaves surpassed sales of gas ranges.

6. Silly Putty

8 Things Invented or Discovered by Accident (2)

It bounces, it stretches, it breaks — it's Silly Putty, the silicone-based plastic clay marketed as a children's toy. In 1943 during World War II, General Electric researcher James Wright dropped boric acid into silicone oil while attempting to create a synthetic rubber substitute. The result was a polymerized substance that bounced, but it took several years to find a use for the product.

In 1950, marketing expert Peter Hodgson finally saw its potential as a toy, renamed it Silly Putty and the rest is history. Kids loved the way they could stretch it out, shape it or roll it up in a ball and bounce it. Perhaps more interesting, though, is that people discovered Silly Putty had loads of practical uses beyond the toy box. The clay picks up dirt, lint and pet hair; can stabilize wobbly furniture; and is useful in stress reduction, physical therapy, and medical and scientific simulations. It was even used by the crew of Apollo 8 to secure tools in zero gravity.


5. Post-it Notes

A Post-it Note is a small piece of paper with a strip of low-tack adhesive on the back that allows it to be temporarily attached to documents, walls, computer monitors and just about anything else. In 1968, 3M scientist Spencer Silver first discovered the novel adhesive, which sticks to surfaces but can also be easily removed. However, he struggled to figure out a use for it.

Meanwhile, fellow 3M scientist Art Fry was annoyed every week during church choir practice, when the little scraps of paper he used to mark the hymns they were working on kept falling out of his hymnal. He needed something that could stick to a page without damaging it. One day he recalled listening to a talk by Silver about his adhesive and had an idea to solve both of their problems — a sticky note.

Fry created the notes and passed them around for his colleagues to try. They loved them. 3M initially launched the product as Press 'n Peel, with tepid results. But eventually they became wildly successful and were renamed Post-it Notes. Although the company was initially skeptical about the product's profitability, in 1980 it went global. Today, Post-it Notes are sold in more than 100 countries.

4. Saccharin

Saccharin, the oldest artificial sweetener, was accidentally discovered in 1879 by researcher Constantin Fahlberg, who was working in the laboratory of professor Ira Remsen at Johns Hopkins University. There's no consensus on exactly how it happened, but one story is that Fahlberg noticed a sweet taste on his hand while working with benzoic sulfimide. Another says he put down his cigarette on a lab bench, and when he picked it up again and took a puff, it left a sweet taste in his mouth. In 1880, Fahlberg and Remsen jointly published the discovery, calling the product saccharin. But in 1884, Fahlberg obtained a patent and began mass-producing saccharin in Germany without Remsen.

While there were health concerns about saccharin as early as 1906, it became popular as a sugar substitute during World War I, when sugar was rationed. Its popularity increased during the 1960s and 1970s when it was promoted as a weight-loss aid, manufactured under the Sweet 'N Low name and placed in diet soft drinks. In the 1970s, food scientists discovered saccharin caused bladder cancer in rats and a warning label was added to the product. However, it was later found that rats and humans metabolize saccharin differently so the warning was removed. Despite the plethora of newer artificial sweeteners, saccharin (and its funny aftertaste) live on.


3. Slinky

8 Things Invented or Discovered by Accident (3)

In 1943, Naval engineer Richard James was trying to develop a spring that would support and stabilize sensitive equipment on ships, which often rocked and rolled on the sea. When one of the coiled wires he was working on accidentally fell off a shelf, it continued moving end-over-end in a curious fashion.

That night, James went home and told his wife, Betty, about the wire. They both agreed it would make a great toy. Intrigued, Betty pored through a dictionary and landed on the name Slinky, as that word is defined as "sleek and sinuous in movement or outline."


In 1945, the couple founded James Industries, and Slinky was born. It wasn't a success at first. So the two convinced a Gimbels department store in Philadelphia to allow them to demonstrate their unconventional toy during the Christmas shopping season. The store had stocked 400 Slinkys, and they were snapped up in less than two hours. But the business almost went bankrupt when Richard joined a religious cult, giving it large sums of money and left the family. Betty mortgaged the house and went to a New York toy show in 1963 and promoted the product again. Orders began to pour in and she was able to revive the business.

Today, more than 300 million Slinkys have been sold worldwide. The toy is so beloved, the U.S. Postal Service issued a Slinky stamp in 1999 and Slinky was inducted into the National Toy Hall of Fame in 2000. There is also a National Slinky Day (Aug. 30) and a historical marker commemorating its invention in Clifton Heights, the Philadelphia suburb where it was first produced.

2. Viagra

In the 1990s, researchers at Pfizer pharmaceutical company were working on a new drug to treat high blood pressure and angina pectoris, a form of cardiovascular disease. The drug, Sildenafil, seemed quite promising, so they began testing it on male volunteers in Wales. Unfortunately, the drug had little effect on angina. But the patients reported a curious side effect: penile erections, occurring as little as 30 to 60 minutes after taking the drug.

It didn't take Pfizer long to realize the drug's immense potential, so the company quickly patented it in 1996. Just two years later the drug received Food and Drug Administration approval for use in treating erectile dysfunction, and it was an immediate and massive success. With some 30 million men in the U.S. reporting erectile dysfunction, Viagra remains one of the most popular drugs on the market. The little blue pill now has competition from other medications such as Cialis (tadalafil) and Levitra (vardnafil).

1. Bubble Wrap

8 Things Invented or Discovered by Accident (4)

In 1957, engineers Alfred Fielding and March Chavannes partnered to create an innovative, textured wallpaper. Their hoped-for consumers were members of the Beat generation — people who eschewed conventional society and embraced Buddhism, free sex, drugs and jazz. The men ran two plastic shower curtains through a heat-sealing machine and ended up with a clear, bubbly sheet that looked intriguing, but bombed as wallpaper.

Undeterred, the two began brainstorming different uses for their novel creation. The second one they tried — greenhouse insulation — also failed. But in 1960, working under their newly formed company, Sealed Air Corp., they took a third stab, promoting it as a protective packaging now known as Bubble Wrap.


Bubble Wrap was an instant success. It was better than the favored packaging material of the day — balled up newsprint — as it provided better protection and didn't leave behind ink smudges. Today there are numerous iterations of the product, and Sealed Air is a Fortune 500 company.
