How Carbonation Works
Carbonation involves dissolving carbon dioxide gas into liquid under pressure. This process stores excess gas within the can. When you open a can, the pressure decreases, allowing gas to escape quickly, creating those bubbly sounds. If a can heats up, the carbon dioxide expands, potentially increasing internal pressure significantly.
Internal Pressure in Cans
Cans are designed to withstand a specific amount of pressure. Most standard soda cans can handle pressures between 30 to 40 pounds per square inch (psi). When temperatures rise, the internal pressure can exceed these limits. For example, a can left in a car on a hot day can reach temperatures of 120°F or more, causing the pressure inside to rise rapidly. In extreme cases, this can lead to the can bursting or leaking. Keep cans in a shaded or air-conditioned place to minimize heat exposure and reduce the risk of explosion.
Factors That Contribute to Explosion
Several factors influence whether soda cans explode in a hot car. Understanding these elements helps you minimize risks.
Temperature Effects
Temperature significantly affects the internal pressure of soda cans. Higher temperatures increase the kinetic energy of the carbon dioxide gas dissolved in the liquid. As temperatures rise, this gas expands, raising the internal pressure within the can. If the temperature climbs beyond the can’s pressure tolerance, typically around 30 to 40 psi, an explosion can occur.
For example, a temperature of 100°F (38°C) can increase the internal pressure of a soda can considerably. Observing this trend shows the critical need to monitor temperatures in hot environments.
Sun Exposure and Heat
Sun exposure directly correlates to the risk of explosion. When soda cans are left in direct sunlight, they absorb heat more rapidly, causing a quicker rise in internal pressure. Even a short duration of sun exposure can increase the temperature inside the can significantly.
For instance, a car parked in the sun can reach temperatures as high as 160°F (71°C) within minutes. The combination of elevated temperatures and pressure can lead to catastrophic failures. To prevent this, park in the shade or cover the cans with a cloth to reduce direct heat exposure.
Real-Life Incidents and Studies
Concerns about exploding soda cans in hot cars are not just hypothetical. Many real-life incidents and scientific studies highlight the risks associated with leaving soda cans in high temperatures.

Anecdotal Evidence
Reports of soda cans exploding in parked cars occasionally surface. One instance involved a group of friends who left a cooler filled with soda in a car on a hot day at the beach. Upon returning, they found a can had burst, spraying soda everywhere. Another case involved a family road trip where cans left on the dashboard exploded during a break, creating a sticky mess. These stories illustrate the potential dangers of negligence when it comes to high temperatures and pressurized containers.
Scientific Research
Research supports the idea that heat increases the risk of explosion. Studies show that internal pressure within a soda can can rise significantly as temperature increases. For example, experiments revealed that a can at approximately 100°F (38°C) may reach pressures of 50 psi or more. At 130°F (54°C), the risk intensifies, potentially exceeding safe limits and leading to failure. Researchers also found that cans left in direct sunlight can heat up more quickly than those in shaded areas. This evidence emphasizes the importance of knowing how heat affects carbonation and pressure in soda cans.
Understanding both anecdotal incidents and scientific findings can help you take preventive measures against the risks associated with leaving soda cans in hot environments.
Preventative Measures
Taking steps to prevent soda cans from exploding in a hot car is key to enjoying your beverages safely. Here are some effective strategies to consider.
Safe Storage Practices
- Keep Cans in Shaded Areas: Store soda cans in shaded spaces when parking outdoors. This reduces direct heat exposure and helps maintain lower temperatures within the vehicle.
- Use a Cooler: Transport cans in a cooler filled with ice or cold packs. This option delays heat absorption and keeps drinks chilled.
- Avoid Direct Sunlight: Place drinks away from windows or dashboard areas where sunlight can intensify heat rapidly. Even partial shade can make a difference.
- Leave in Air Conditioning: If you can, park in air-conditioned areas. This significantly minimizes temperature fluctuations.
- Bulging Can: If the can shows signs of bulging, this indicates increased internal pressure and higher risk of explosion.
- Unusual Hissing Sounds: Listen for unusual hissing or popping sounds when opening. This can suggest excessive pressure buildup.
- Liquid Leak: Be cautious if you notice any liquid leakage around the can. This may mean the can has already been compromised.
- Feel for Warmth: If a can feels unusually warm to the touch, internal pressure has likely risen. Handle with caution to avoid any accidents.
