The convenience of quickly chilling a beverage by placing it in the freezer is a common practice in many households. However, this seemingly harmless habit can sometimes lead to unexpected and serious consequences. Understanding the science behind why certain items, especially carbonated drinks, should not be frozen is important for maintaining safety in the home.
Freezing Carbonated Beverages: What Happens Inside?
Carbonated beverages contain dissolved carbon dioxide gas under pressure, which creates the familiar fizz when opened. When such a drink is placed in a freezer, the liquid begins to cool and eventually freezes. As the liquid freezes, it expands in volume—water expands about 9% when it turns to ice. This expansion increases the pressure inside the sealed container.
Because the container is tightly sealed, the build-up of pressure can cause it to deform or even rupture. This can result in the can or bottle bursting, sometimes violently, sending shards of metal or glass outward and posing a significant risk of injury.
Common Injuries and Risks
Incidents involving exploding cans in freezers have led to various injuries ranging from minor cuts to more severe lacerations. Medical professionals have observed an increase in such injuries, especially among children who may not be aware of the risks involved. These accidents can cause permanent scars and require medical attention, including stitches.
Other Items to Avoid Freezing
Besides carbonated drinks, other items such as sealed alcohol bottles can also present risks when frozen. Alcohol has a lower freezing point than water, but when frozen in tightly sealed containers, pressure can still build up. Dry ice, often used for cooling purposes, must be handled with care and stored in ventilated containers to prevent gas buildup and potential rupture.
Safe Practices for Cooling Drinks
To minimize the risk of accidents, it is advisable to avoid putting carbonated beverages and sealed alcohol containers in the freezer. Instead, use a refrigerator to cool drinks gradually. For quicker chilling, ice buckets or ice baths can be effective and safe alternatives.
Educating Children and Household Members
Teaching children about the potential dangers of placing certain items in the freezer is essential. Simple instructions and supervision can prevent experimentation that might lead to accidents. Encouraging safe habits around kitchen appliances contributes to a safer home environment.
Emergency Preparedness and Response
In the event of an explosion or injury involving frozen containers, it is important to act promptly. Clean up any broken container pieces carefully to avoid further harm, and seek medical attention if injuries occur. Being prepared with basic first aid knowledge can make a significant difference in managing such incidents.
Conclusion: Preventing Freezer-Related Injuries
While freezing beverages or other items might seem convenient, the risks associated with it, particularly with carbonated drinks, should not be underestimated.

The Role of Packaging Materials in Freezer Safety
Packaging materials significantly influence the safety of storing beverages and other liquids in the freezer. Cans made of thin metal are especially vulnerable to pressure changes caused by freezing liquids inside them. Glass bottles, while often sturdier, pose their own risks; if the liquid inside expands during freezing, glass can shatter, sending dangerous shards outward. Plastic bottles tend to be more flexible but are not immune to ruptures or leaks when liquids expand upon freezing. Understanding the characteristics of different packaging can help consumers make safer choices about what to store in the freezer.
How Temperature Variations Affect Freezer Safety
Temperature fluctuations within the freezer can exacerbate risks. Freezers that do not maintain consistent temperatures may cause liquids to partially freeze and thaw repeatedly, increasing pressure changes inside sealed containers. These cycles can weaken the packaging over time, making containers more susceptible to bursting. Regularly checking and maintaining freezer temperatures within recommended ranges can reduce these risks.
The Chemistry Behind Carbonation and Pressure Build-Up
Carbonation involves dissolving carbon dioxide (CO₂) gas in liquid under pressure. When the beverage is sealed, the gas remains dissolved, giving the drink its characteristic bubbles upon opening. Cooling the beverage in a freezer causes the liquid to freeze and expand, but the gas also responds to temperature changes. As the temperature drops, the solubility of CO₂ increases initially, but once freezing begins, gas can separate and increase pressure inside the container. This interplay between liquid expansion and gas behavior is a key factor leading to container failure.
Understanding Dry Ice Handling and Storage
Dry ice, solid carbon dioxide, sublimates directly from solid to gas at temperatures above -78.5°C (-109.3°F). Improper storage of dry ice in airtight containers can cause dangerous pressure build-up as the gas has no escape route. To safely use dry ice for cooling, it should be stored in well-ventilated containers that allow gas to dissipate. Additionally, it is important to handle dry ice with insulated gloves to prevent frostbite and to ensure adequate ventilation in areas where dry ice is used to avoid carbon dioxide buildup in the air.
Safe Alternatives to Freezing for Rapid Cooling
For those seeking faster cooling methods without freezing risks, several alternatives exist. Ice buckets or ice baths filled with water and ice provide rapid chilling while avoiding pressure buildup. Specialized beverage chillers and cooling sleeves use conductive materials to cool drinks safely without freezing them. Additionally, some refrigerators offer quick-chill compartments designed to cool beverages faster without the dangers associated with freezing.
