Sometimes, accidents can lead to wonderful inventions, such as in the cases below.

Post-It Notes

In 1968, Dr. Spencer Silver was trying to invent super strong glue which cried immediately. However, he was not successful and could only invent a very weak glue that never seemed to dry. And that was how the Post-it note was invented by chance.

Coca-Cola

In 1886, John Pemberton was trying to find a cure for headaches. He tried to mix together some ingredients, but when his lab assistant added fizzy water by accident, the world's first Coca-Cola was born.

Crisps

In 1853, a chef named George Crum received complaints from a customer at his restaurant that the fried potatoes he cooked were too thick and bland. He was so annoyed that he decided to slice the potatoes as thin as possible, fry them and add a lot of salt. To his surprise, the customer loved the dish, and we have also loved it until today as well!
