Popsicle was invented by an 11 year old who kept it secret for 18 years.

The inventor was Frank Epperson who, in 1905, left a mixture of powdered soda and water out on the porch, which contained a stir stick. That night, temperatures in San Francisco reached record low temperature. When he woke the next morning, he discovered that it had frozen to the stir stick, creating a fruit flavored ice treat that he named the epsicle. 18 years later he patented it and called it the Popsicle.

The ice pop was introduced to the public at an Oakland ball for firemen in 1922. The Popsicle company claims that its annual sales are over two billion and that its best-selling flavor is cherry.
