An ice pop is water or milk-based frozen snack on a stick. Unlike ice cream or sorbet, which are whipped while freezing to prevent ice crystal formation, an ice pop is “quiescently” frozen—frozen while at rest—and becomes a solid block of ice. The stick is used as a handle to hold it. Without a stick, the frozen product is known as something else (e.g. a freezie).

The Popsicle was accidentally invented in 1905 by 11-year-old Frank Epperson. Epperson left a mixture of powdered soda and water and a stirring stick in a cup on his porch. … Epperson changed the name of his treat to “Popsicle”, after his children always asked for “Pop’s ‘sicle”, and signed up for a patent.

“They may be a low-calorie choice, but they aren’t satiating calories,” says Allison Stowell, RD. “A Popsicle won’t fill you up as an afternoon snack.” That means you’re likely to reach for yet another bite before dinner.
