If you order food off the TV or Internet, it often comes in a polystyrene box with lid or a cardboard box with aluminized cardboard insulators, and a small bag of solid cryogenic cold CO2 called "Dry Ice" made of solid carbon dioxide that sublimates directly into CO2 gas without making a liquid phase, very unlike frozen water ice that melts into liquid water, thus the name "Dry" because of the transition from solid to gas without any liquid or "wet" stage.

Holding the dry ice bag over a water filled toilet, you can cut the bottom of the bag open with scissors allowing the dry ice to fall into the water, where heat in the water will cause the dry ice to sublimate directly into very cold CO2 gas which causes trillions of tiny chilled water vapor droplets to form making a cold water vapor emit from the surface like a small cloud in your toilet or bowl of punch of similar liquids. This can be done with coffee or juice or any fluid beverage above 0 F, as the dry ice much colder and will sublimate with the heat of fluids significantly hotter than the dry ice :)
