Have you ever pulled a soda out of the freezer only to find it exploded all over the place? It’s a frustrating moment that many of us have experienced. You just wanted a cold drink, but instead, you’re left with a sticky mess to clean up.
Key Takeaways
- Soda Composition: Understanding that soda is made up of carbonation, sugar, and water is key to knowing why it can explode when frozen.
- Carbonation and Pressure: The dissolution of carbon dioxide in soda creates pressure; when temperatures drop, bubbles form and pressure increases, leading to potential explosions.
- Freezing Point: Soda’s lower freezing point (around 28°F) compared to water allows it to remain liquid longer, but sudden removal can cause violent eruptions due to pressure changes.
- Temperature Effects: Rapid temperature fluctuations and ice crystal formation in the freezer contribute significantly to increased internal pressure within the container.
- Preventive Measures: Best practices include storing soda in the fridge, avoiding long freezer stays, using plastic containers, and carefully thawing frozen soda to minimize explosion risks.
Understanding Soda Composition
Soda combines carbonation, sugar, and water, creating a unique beverage experience. Understanding its composition helps explain why soda can explode in the freezer.
Carbonation and Pressure
Carbonation comes from dissolved carbon dioxide gas in the liquid. When you shake or agitate a soda, this gas forms bubbles, increasing pressure inside the can or bottle. In the freezer, the temperature drops, causing the carbon dioxide to become less soluble, which can lead to bubbles forming more quickly. The increased pressure from these bubbles can exceed the container’s capacity, causing it to burst.

Freezing Point of Soda
The freezing point of soda is lower than that of water due to its sugar and carbonation content. While pure water freezes at 32°F (0°C), soda typically freezes around 28°F (-2°C). When placed in the freezer, soda can remain liquid even at sub-zero temperatures. The combination of pressure and lower freezing point creates a situation where soda can remain liquefied longer before rapidly expanding upon removal. When you open the container, the sudden release of pressure leads to a violent eruption of soda.
The Freezing Process
Understanding the freezing process of soda reveals why it can explode in your freezer. Several factors contribute to this phenomenon, primarily temperature changes and ice crystal formation.
How Temperature Affects Liquid
Temperature plays a crucial role in the state of liquids. When you place soda in the freezer, the temperature drops significantly, often below 32°F (0°C). As the temperature decreases, the solubility of carbon dioxide in the soda diminishes. The dissolved gas begins to escape, forming bubbles. If the soda is agitated, like when you shake it or move it, the pressure inside the container increases rapidly. This pressure buildup, combined with the cold temperature, sets the stage for an explosive situation.
Formation of Ice Crystals
Formation of ice crystals is another key factor in soda’s explosive behavior. Soda has a lower freezing point than water due to its sugar and carbonation content. As the soda stays in the freezer, ice crystals begin to form. These crystals disrupt the equilibrium of the liquid, causing rapid expansion. The rapid formation of ice and the expansion of gases increase the internal pressure within the can or bottle. When you finally open the container, the release of pressure leads to a chaotic eruption of soda, resulting in a sticky mess.
Causes of Exploding Soda
Soda explodes in the freezer due to a combination of factors that create excessive internal pressure. Understanding these causes can help prevent future explosions.
Expansion of Carbon Dioxide
Carbon dioxide (CO₂) is a key ingredient in soda, providing the characteristic fizz. As you cool soda in the freezer, the solubility of CO₂ decreases. The gas begins to escape from the liquid, forming bubbles rapidly. If the soda stays in the freezer too long, the buildup of bubbles leads to significant pressure inside the container.

When the temperature drops below 32°F (0°C), liquid CO₂ undergoes rapid expansion, contributing to this pressure. Even minor movements, like taking the soda out for a quick check, can cause agitation, worsening the bubble formation and pressure increase.
Increased Pressure Inside the Can/Bottle
The pressure inside a soda can or bottle can reach dangerous levels. Most soda containers are designed to hold a pressure range of 30 to 50 psi (pounds per square inch). When the soda freezes, you might notice the liquid expands as ice forms. This process further increases internal pressure, often surpassing the container’s limits.
Opening a can or bottle with high pressure results in an explosive release of soda. The combination of the pressure buildup and the rapid expansion of CO₂ leads to an eruption of sticky beverage. To avoid this, check your soda often and avoid keeping it in the freezer for too long.
Preventive Measures
You can avoid the hassle of exploding soda by implementing a few simple strategies. By following best practices for storage and thawing, you minimize the risk of a messy cleanup.
Best Practices for Storing Soda
- Keep Soda in the Refrigerator: Storing soda in your refrigerator instead of the freezer keeps it at an ideal drinking temperature without the risk of freezing.
- Resist the Temptation to Chill Quickly: If you want a cold drink, set a timer for 15 minutes. This way, you can enjoy a chilled soda without freezing it.
- Choose Appropriate Containers: Use plastic bottles instead of glass containers. Plastic can flex under pressure, which reduces the chance of breakage.
- Monitor Temperature Settings: Ensure your freezer isn’t set too cold. The ideal temperature for a freezer is 0°F (-18°C) to avoid freezing your sodas too quickly.
- Storing Upright: Store soft drink bottles upright to prevent internal pressure buildup associated with shaking or agitation.

- Move Soda to the Fridge: If you accidentally freeze a can, place it in the refrigerator for gradual thawing. This reduces the risk of pressure buildup.
- Run Under Cold Water: For quicker results, run the container under cold water. This thaws the soda without creating rapid pressure changes.
- Avoid Countertop Thawing: Skip leaving soda on the counter. Rapid temperature changes increase the risk of pressure buildup.
- Open Slowly: If you suspect carbonation buildup, gently open the can or bottle. This releases pressure slowly, reducing the chance of an explosion.
- Give Time: Allow any frozen soda to rest for an adequate period before attempting to open it. Waiting ensures the carbon dioxide has a chance to stabilize.
Implementing these preventive measures helps ensure a pleasant soda experience by reducing the likelihood of explosive mishaps.
Conclusion
Next time you reach for a cold soda from the freezer keep these tips in mind to avoid a messy explosion. Understanding the science behind why soda reacts this way can help you prevent those frustrating moments. By storing your drinks in the fridge instead of the freezer and monitoring them closely you can enjoy a refreshing beverage without the sticky cleanup. With just a little care you can savor your soda without any surprises. Cheers to that!
Frequently Asked Questions
Why does soda explode in the freezer?
Soda explodes in the freezer due to increased pressure from carbonation. As it cools, carbon dioxide becomes less soluble, forming bubbles that increase pressure inside the container. When you open it, the rapid release of this pressure causes an explosive eruption.
What should I do if my soda is frozen?
If your soda is frozen, move it to the refrigerator to thaw slowly. You can also run the container under cold water to help the thawing process. Avoid shaking the soda before opening to prevent an explosion.
How can I prevent soda from exploding in the freezer?
To prevent soda explosions, store it in the refrigerator instead. If you must chill it quickly, set a timer to avoid leaving it too long in the freezer. Always keep bottles upright and avoid agitation.
What is the freezing point of soda?
Soda has a lower freezing point than water, typically around 29°F (-2°C) due to its sugar and carbonation. This allows it to remain liquid below the standard freezing point of water.
Can I still drink frozen soda?
While you can potentially drink frozen soda, it may be best to thaw it first to avoid an explosive mess when opening. Opening a fully frozen soda can cause a rapid release of pressure, leading to spills.
