#1 High-Heeled Shoes
High-heeled shoes can be traced back to the 10th century in Persia, when they were primarily worn during horse riding. By the 17th century in Europe, they became a symbol of masculinity and high social status for men. However, by the 18th century, high-heeled shoes began to filter into women’s fashion. Now, centuries later, women mostly wear them because they represent femininity.

The dashboard wasn’t always the sophisticated car accessory it is today. In the times when horse carriages were the mode of transportation, the dashboard was just a wooden board used to shield the people in the carriage from the dirt and debris brought up by the horses’ galloping. Now, it has been transformed into a high-tech accessory that relays information and performs an unlimited range of functions.

#8 Viagra
This ‘potency’ pill was discovered accidentally when researchers at Pfizer attempted to develop a medicine for treating heart problems. The active ingredient in Viagra, Sildenafil, was meant to dilate the blood vessels in the hearts of the test subjects, but instead seemed to dilate the blood vessels in their penises, leading to erections. And with that, Viagra was officially born.

Before it became the world’s most popular soft drink, Coca-Cola was created as a substitute for morphine by pharmacist John Pemberton in 1886.

Now, it’s marketed as a great-tasting beverage instead of a cure-all medicine.

By subjecting the hardened criminals to forced labor, prison administrators had hoped they would be rehabilitated.

It’s hard to believe that Play-Doh was anything other than a kid’s toy. First manufactured in Ohio in the early 1900s, it was originally used as a wallpaper cleaner. But once the need for wallpaper fell away in the ‘50s, the putty was transformed into the much-loved children’s toy. Today, over 3 billion cans of Play-Doh have been sold since its debut in 1956.

When copyright was first created in the 1700s, it was intended to cover books only. It gave authors limited exclusive rights to print their books for relatively short periods of time. Over three centuries later, copyright extends to a wide range of works such as music, films, photos, and so much more. Copyright owners are also provided with longer protection terms now than they were before.

#19 Dynamite
Swedish scientist, Albert Nobel, invented dynamite to assist the building and mining industry. But eventually, others began using it to make explosives and rockets for use in the war. So, what was initially created to help people ended up hurting them and causing catastrophic damage to structures. Out of guilt, Nobel even donated his life’s earnings to create the Nobel Peace Prize to award important inventions that brought good instead of harm to humanity.
