Yes, dry ice can keep things frozen. Dry ice is solid carbon dioxide and is colder than the frost-free freezer at your home, at a chilly -78.5°C (-109.3°F). It's especially useful for shipping frozen items or keeping things frozen during a power outage. However, handle it with care using insulated gloves, and ensure good ventilation where it's stored to prevent carbon dioxide buildup.
