Abstract: A unitary mold for making ice sculpture includes: a mold made of elastomer material having an inner cavity concave downwardly for forming a model of an ice sculpture such as an animal, a building or a person or an article; a perforating bar or needle poking through the mold which can be warmed up to slightly melt the ice surrounding the bar or needle for its easy withdrawal from the ice product and forming a through hole of the ice sculpture for decorative, carrying, or water-drainage purposes; and an expansion-releasing element such as a flip-flop member formed as a part of the mold, serving as a buffer for the expansion of the water during its refrigeration process.
