Almost all popular inventions today were created by scientists who had a very specific idea and went on to materialize it. To invent something, you have to go through a series of experiments with different calculations. However, in some cases experiments can go wrong, resulting in you creating something you never intended to make – a great product. Everyone on this list may not be a scientist, or even successful at what they do, but they had enough luck to create products that we simply can’t live without.

#1 – Coca-Cola

Towards the end of the 19th century, an unsuccessful pharmacist named John Pemberton had one simple goal – to create a medication that would cure headaches. Initially, the drink contained cocaine (this was a time when cocaine was legal and used for medical purposes in the United States), which is exactly why it used to make your headache stop. However, people found the taste of the beverage very addictive even after cocaine was removed from the ingredient list, making their beverage the most recognizable soft-drink brand in the world.
