11-year-old Frank Epperson revolutionized frozen treats completely by accident. In 1905, he tried to create a new type of soda with his not-yet patented original syrup. When the experiment failed, Frank left it outside overnight. In the morning, he realized that frozen sweet soda makes for a great and easy-to-eat dessert. A year later, the kid started selling the novelty snack in parks and cinemas before eventually patenting the recipe and becoming rich.
