Not every great idea began as one. Some of the world’s most useful inventions started with failure, chance, or a simple twist of curiosity. Here are ten everyday things that came from unexpected beginnings.

Bubble Wrap

Invented in 1957 when engineers Alfred Fielding and Marc Chavannes tried to make textured wallpaper by sealing two plastic shower curtains together. The wallpaper idea failed, as did their attempt to sell it as insulation. Then IBM saw potential. In 1959, IBM became the first company to use Bubble Wrap to ship delicate computer parts safely, and packaging history was made.

Insulin

In 1921, Canadian physician Frederick Banting tied off a dog’s pancreatic ducts to study its effect on digestion. What he found instead was a substance that regulated blood sugar — insulin — which transformed diabetes from a fatal disease into a treatable one.

Laughing Gas as an Anesthetic

In the 1840s, nitrous oxide was used mostly at parties for amusement. Dentist Horace Wells attended one of these demonstrations and noticed that people injured under its effects felt no pain. He tried it in his dental practice, and anesthesia was born.

The Hypodermic Needle

The modern syringe was inspired by nature. Early 19th-century physicians studying snake fangs realized venom delivery worked like precision injection, leading to the first hollow needles for controlled dosing.

The Airbag

The idea came from a watchmaker named Walter Linderer in the 1950s. He used compressed air to create an impact-cushioning system decades before car safety standards required it. Later refinements turned it into one of the most important automotive safety devices ever made.

The Jet Engine

Invented independently by Frank Whittle in Britain and Hans von Ohain in Germany in the 1930s. Both were ignored by their governments at first, but their designs eventually powered the modern age of flight.

The Frisbee

Before it flew through the air, it held pies. The Frisbie Pie Company of Connecticut sold tins stamped “Frisbie’s Pies.” College students began tossing them for fun in the 1940s, and a toy maker later turned the pastime into the flying disc we know today.

The Toothbrush

The modern toothbrush was created in 1770 by an Englishman named William Addis while in prison. He drilled holes into an animal bone, inserted bristles from a boar, and changed oral hygiene forever.

Bubble Gum

In 1928, accountant Walter Diemer was experimenting with new gum recipes in a candy factory when one batch turned out unusually stretchy. He dyed it pink — the only color on hand — and sold it as the first bubble gum.

The Dishwasher

In the 1880s, Josephine Cochrane grew tired of servants chipping her fine china. Determined to find a better way, she designed a hand-cranked machine that used water pressure to clean dishes efficiently. Her invention became the first practical dishwasher and earned her a patent — a rare achievement for a woman of her era.

Accidents, mistakes, and small observations have changed more than history — they’ve shaped daily life. Sometimes genius begins when something doesn’t go as planned.
