why is my soda can squishy

Have you ever picked up a can of soda, only to find that it feels squishy? You may be wondering why this is the case. As it turns out, there are a few reasons why your soda can may be squishy.

Whether it’s due to a manufacturing defect, changes in temperature, or other factors, understanding the underlying causes can help you prevent this issue in the future.

Identifying the issue

Now that we know that a squishy soda can is not an uncommon occurrence, let’s dive into the science behind this phenomenon. When a can of soda feels squishy, it’s often due to changes in temperature or excessive pressure build-up.

Temperature plays a significant role in the integrity of a soda can. If a can is exposed to high temperatures, such as being left in a car on a hot day, the heat causes the liquid inside to expand. This expansion results in increased pressure within the can, which can lead to the can feeling squishy.

In some cases, a manufacturing defect can also be to blame. Improperly sealed soda cans can allow air or moisture to enter, leading to carbonation leaks and subsequent squishiness.

Common reasons for a squishy soda can

Now that we understand the science behind a squishy soda can, let’s explore some of the common reasons why it may occur.

1. Temperature changes:

As previously mentioned, temperature fluctuations can cause a soda can to feel squishy. Extreme heat or cold can affect the pressure inside the can and lead to the squishiness. To avoid this, try to store your soda cans in a cool and dry place, away from direct sunlight or extreme temperatures.

2. Overcarbonation:

Sometimes, excessive carbonation can make a soda can feel squishy. This can happen when the can is shaken or jostled, causing the carbonation to release and build up pressure, making the can appear squishy. It’s important to handle your soda cans gently to prevent this.

3. Manufacturing issues:

While rare, manufacturing defects such as improper sealing can result in air or moisture entering the can. This can lead to carbonation leaks and subsequently cause the can to feel squishy. Checking the seal on your soda can before purchasing can help you avoid this issue.

Proper storage and handling to prevent soda can squishiness

Proper storage and handling of soda cans can play a crucial role in preventing their squishiness. Here are some practical tips to help you keep your soda cans firm and properly carbonated:

Store in a cool place:

To maintain the right pressure inside the can, it is essential to store your soda cans in a cool and dry place. Avoid exposing them to direct sunlight or extreme temperatures, as these can cause temperature fluctuations and make the cans feel squishy.

Avoid excessive shaking:

Be cautious while handling soda cans to prevent excessive shaking or jostling. Rough handling can cause the carbonation to release and build up pressure, making the can squishy. Handle your soda cans gently, especially when transporting or opening them.

Check seals before purchasing:

Occasionally, manufacturing defects can cause air or moisture to enter the can, leading to carbonation leaks. Before purchasing soda cans, always check the seal to ensure it is intact. This simple step can help you avoid buying cans that may feel squishy.

Potential safety concerns with a squishy soda can

While a squishy soda can may seem harmless, it is important to be aware of potential safety concerns that can arise from this issue. When a soda can becomes squishy, it often means that the carbonation inside is compromised. This can lead to various problems, such as:

1. Risk of explosion:

When the pressure inside the can suddenly increases due to compromised carbonation, there is a higher risk of the can exploding. This can result in injuries from flying metal shards or liquid.

2. Consumption of flat soda:

A squishy can indicates that the carbonation has escaped, leaving you with a flat soda. Consuming flat soda may not only be disappointing in terms of taste but can also lead to an upset stomach if consumed in large quantities.

3. Contamination:

If the squishiness is caused by a faulty seal or a tiny hole, it can allow air, moisture, or even bacteria to enter the can, potentially contaminating the beverage.

So, it is crucial to take squishy soda cans seriously and handle them with caution.

What to do if you encounter a squishy soda can

When you come across a squishy soda can, it is important to handle it properly to avoid any potential safety issues. Here are some steps you can take to address the problem:

1. Check for leaks:

Carefully inspect the can for any signs of leakage or tiny holes. If you find a leak, it is best to discard the can immediately to prevent the risk of contamination.

2. Open with caution:

If there are no visible leaks, open the can slowly and be prepared for any sudden releases of pressure. Point the opening away from your face and body to avoid potential injuries.

3. Taste test:

Once the can is open, take a small sip to check if the soda is still carbonated. If the taste is flat and lacking fizz, it may be best to dispose of the soda rather than consume it.

4. Store correctly:

To prevent future squishiness, make sure to store your soda cans in a cool and dry place away from direct sunlight and extreme temperatures.


Maintaining the quality of your soda cans is crucial in preventing them from becoming squishy. In this blog section, we will discuss a few additional tips to help you keep your soda cans in optimal condition.

Avoid stacking:

When storing your soda cans, it is important to avoid stacking them on top of each other. The weight from the cans above can cause dents and deformities, making them more susceptible to becoming squishy.

Handle with care:

Be mindful of how you handle your soda cans, especially when transporting them. Rough handling or dropping the cans can cause internal damage, leading to a squishy texture.

Expiration dates:

Always check the expiration dates on your soda cans before consuming them. Over time, the carbonation in the soda can deteriorate, resulting in a flat taste and potential squishiness.
