Invented accidently by 11 year old Frank Epperson in 1905, they were originally called Epsicles! It would be 18 years before he realized that there were commercial possibilities, and in 1923 he applied for a patent, which was granted in 1924. His kids would ask for pop's 'sicles', and so the name Popsicle was born.
Epperson also created the twin popsicle, the Fudgsicle, the Dreamsicle and the Creamsicle.
Popsicle sticks are made from birch wood.
The Twin Popsicle was invented during the Great Depression so 2 could share one for a nickel.
Good Humor owns the rights to the popsicle, and according to the company, 1.4 billion sticks were used to make Popsicle products - that is more than 9 million miles of sticks! (2001)
