Liquid nitrogen cocktail Liquid nitrogen cocktail A liquid nitrogen cocktail is any mixed drink whose preparation involves the use of liquid nitrogen. Popularized as a novelty because of the smoky, bubbling "cauldron effect" it produces, liquid nitrogen is controversial as a cocktail ingredient because it boils at and its consumption is thus potentially lethal. However, it is not a regulated substance in most countries and there is little control of its use.
