Why Are Some Ice Cubes Cloudy While Others Are Clear?

The video explains why ice cubes from home freezers are often cloudy compared to the clear ice cubes found in high-end bars. It clarifies that while water quality plays a role, the main factors are impurities and the cooling process. Impurities in water, such as minerals, become visible as ice forms, causing cloudiness. Home freezers cool water rapidly, trapping air bubbles that contribute to the cloudy appearance. Professional ice makers use slow freezing techniques to create clear ice by allowing air bubbles to escape. The video also suggests methods to achieve clear ice at home, like using boiled water and slow freezing.
