Dry ice is used more for decorations, and for entertaining.
But you Absolutely do not want to use dry ice in drinks, because dry ice is made from pure carbon dioxide. You never want to let dry ice touch your bare skin.
Dry ice displaces oxygen in the air, so always use it in a well-ventilated area. If using dry ice in a confined space, open the door and air out the area.
