Sometimes we get mad at ourselves when we make mistakes … but not all mistakes are bad! Some of our favorite foods were created by accident! Check these out:

Popsicle

In 1905, an 11-year-old kid named Frank Epperson was making soda pop by stirring powdered soda flavoring into a bucket of water. He accidentally left the mixing bucket outside with some of the soda-and-water mixture in it. It was freezing cold that night, and the next morning Frank discovered that the mixture had frozen solid. Of course, he tasted it and it tasted great! He called them "Epperson Icicles" and started selling them for 5¢ each. (Later, he changed the name to "popsicles.")

Sandwich

Way back in the 1700s, there was a man called the Earl of Sandwich. (Earl is a royal title and Sandwich is the name of the county that his family was from.) The Earl loved to gamble and wanted to play all day and night. One day, he was so busy gambling that he didn't even want to stop at mealtime. Instead, he told the kitchen staff to stuff some food between two slices of bread so he could eat with one hand and gamble with the other. The sandwich caught on and has been popular ever since.

Chocolate chip cookies

Ruth Wakefield had a job as a cook at the Toll House Inn in Whitman, Massachusetts back in 1930. She usually made cookies with baking chocolate—but one day she ran out. Thinking quickly, she broke a bar of semisweet chocolate into tiny pieces and stirred them into the cookie dough. When she took the cookies out of the oven, she saw that the chocolate chips hadn't melted. Instead of making chocolate cookies, she had accidentally invented chocolate chip cookies. They were an instant hit.

Potato chips

George Crum was a chef at the Moon Lake Lodge in Saratoga Springs, New York in 1853. One day, one of his customers complained that the french fries were too thick. Mr Crum sliced a potato into thinner pieces and fried those. The customer complained that those were too thick, too. Mr Crum felt insulted. This time, he sliced a potato into super-thin slices and fried them until they were crunchy. The customer loved them and soon everybody wanted some. 

Ice cream cone

In 1904, Ernest Hamwi was busily selling Syrian pastries at the St Louis World's Fair. One day, an ice cream vendor operating a stand near his ran out of dishes. Wanting to help, Mr Hamwi rolled up one of his pastries into a cone and stuffed some ice cream inside so the customers wouldn't have to touch the ice cream with their hands. People loved this new way of eating ice cream. However, a man named Italo Marchiony got a patent to make ice cream cones that same year—so it's possible that two people invented the ice cream cone around the same time and didn't know it.
