Frank Epperson, a little boy from the San Francisco Bay Area, unintentionally created this summertime treat back in 1905. He had left a mixture of water and sweet soda powder out overnight. Because of the chilly night, the mixture froze. The next day, Epperson licked the iced mixture off the wooden stirrer. Incorporating his name with the word “icicle,” he dubbed it a “Epsicle” and began selling it in his area.
