Popsicle is a popular brand of ice pop in the United States and Canada and became a genericized trademark for any type of ice pop due to its popularity. The first ice pop was created by accident in 1905 when 11-year-old Frank Epperson left a glass of homemade soda on his porch on a very cold San Francisco night. The next morning he went to go get the soda and it was frozen. Using the stirring stick that he had also left in the glass, he pulled it out and tried it. 'Popsicle' is a trademark held by Unilever. In 1905 in San Francisco, 11-year-old Frank Epperson was mixing a white powdered flavoring for soda and water out on the porch. He left it there, with a stirring stick still in it. That night, temperatures reached a record low, and the next morning, the boy discovered the drink had frozen to the stick, inspiring the idea of a fruit-flavored 'Popsicle', a portmanteau of soda pop and icicle. In 1922, he introduced the frozen treat at a fireman's ball. It was a sensation.
