Popsicles

 In 1905 an eleven-year-old Frank Epperson was mixing powdered soda and water to make soda pop.

Frank accidentally left the mixing bucket outside. During the night the mixture froze solid, with the wooden stirring stick standing straight up. 

But the frozen pop tasted great! Frank started selling Epperson icicles for five cents, later changing the name to popsicles.
