An ice pop is a water or milk-based quiescently frozen snack on a stick. Unlike ice cream or sorbet, which are whipped while freezing to prevent ice crystal formation, an ice pop is 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). Ice pops can also be referred to as a popsicle (Canada, U.S., New Zealand), freezer pop (U.S.), ice lolly, ice pop (United Kingdom, India, Ireland, South Africa), ice block (Australia), ice drop in the Philippines or paleta (Mexico).
