One of the most recognizable frozen products in America could have originated from a child's simple mistake. According to the widespread version of how the Popsicle was invented, an eleven-year old boy named Frank Epperson accidentally left his lemonade with a stirring stick outside overnight in San Francisco in 1905.
As a result, a few hours later, when he woke up, he found out that his lemonade had frozen along with the wooden stick stuck inside. Although the details may not be absolutely confirmed, some of the evidence from patents and business history shows that indeed Epperson managed to transform his simple invention into a marketable product.
