Ever wondered what happens if you leave a soda in the freezer for too long?

You might be surprised to learn that it could explode causing quite a mess!

This article will break down why this occurs, including how carbonation and the water content of your drink contribute to potential explosions.

Read on to understand this fizzy phenomenon and how to prevent any soda exploding disasters in your freezer!

What Causes Soda to Explode in the Freezer?

What Happens If You Leave Soda In The Freezer (1)

Expansion of water in the soda can

Water in a soda can grows when it freezes,this is because the liquid turns into ice. The space inside the can gets smaller.

Then, the pressure goes up,the can may break or pop open due to this high pressure from the frozen water and CO2 gas inside.

This happens with all fizzy drinks that have water like soda does.

Carbon dioxide pressure build-up

Leaving soda in the freezer can cause a build-up of carbon dioxide pressure inside the cans. When you freeze soda, the dissolved carbon dioxide gas doesn’t have anywhere to escape, so it builds up and creates more pressure in the can.

As a result, if there is too much pressure inside the can, it can explode when you open it or thaw it out. This is why it’s important to consume soda before it becomes frozen solid to prevent any accidents from happening.

So be cautious and don’t leave your soda in the freezer for too long!

Can Soda Cans Explode in the Freezer?

Soda cans in the freezer can indeed explode due to the expansion of water and build-up of carbon dioxide pressure.

Factors that contribute to soda can explosions

Soda cans can explode in the freezer due to certain factors. Here are some important factors to consider:

  • Overpacking: If you overcrowd the freezer with too many soda cans, there is not enough space for expansion, leading to increased pressure and potential explosions.
  • Freezing time: Leaving soda in the freezer for too long increases the chances of it exploding. As mentioned before, frozen soda becomes slushy instead of turning into a solid block.
  • Carbon dioxide build-up: The dissolved carbon dioxide in carbonated drinks creates pressure inside the can. When small amounts of soda freeze, this pressure builds up and can cause the can to pop open.
  • Temperature fluctuations: Frequent changes in temperature within the freezer can also contribute to cans exploding. Fluctuations in temperature cause expansion and contraction of the liquid inside, increasing pressure on the container.
  • Quality of cans: Damaged or faulty cans are more likely to explode when placed in a freezing environment. It’s important to check for any dents or leaks before putting them in the freezer.

How Long Can Soda be Left in the Freezer Before It Explodes?

Recommended time limit for freezing soda

It is recommended not to leave soda in the freezer for more than 2 hours to prevent it from exploding. The longer you leave soda in the freezer, the higher the chances of it bursting.

This is because when carbonated drinks freeze, they expand and can cause the cans or bottles to burst due to increased pressure inside.

So, if you want to enjoy a refreshing drink without any accidents, make sure not to leave your soda in the freezer for too long!

Effects of prolonged freezing on soda quality

Leaving soda in the freezer for too long can affect its quality. When soda is frozen, it expands and can lose some of its carbonation. This means that when you open the can or bottle, it may not be as fizzy as before.

Additionally, if the soda is left in the freezer for an extended period of time, it can develop a slushy texture instead of being liquid.

It’s important to consume frozen soda before it thaws completely to avoid any potential accidents or messes.

So, make sure to check on your soda if you’ve accidentally left it in the freezer for too long!

Alternative Methods to Cool Soda

Quick cooling techniques

If you need to cool your soda quickly, here are some methods you can try:

  1. Ice Bath: Fill a container with ice and water, then place the soda can or bottle in it. The cold temperature of the ice bath will help cool the soda faster.
  2. Wet Paper Towel Method: Take a paper towel and wet it with cold water. Wrap the wet paper towel around the soda can or bottle, then put it in the fridge for a few minutes. The evaporation of the water on the towel will create a cooling effect.
  3. Freezer Wrap: Wrap the soda can or bottle in a damp paper towel and place it in the freezer for about 15 minutes. Make sure to set a timer so you don’t forget about it and risk explosions.

Using ice or a refrigerator

To cool soda quickly, you can use ice or put it in the refrigerator. If you want to cool your soda fast, just add some ice cubes to a glass and pour your soda over them.

The ice will help lower the temperature of the drink and make it colder in no time.

Another option is to place the soda can or bottle in the refrigerator for a few hours. This will gradually bring down its temperature and make it refreshing when you’re ready to enjoy it.

Remember not to leave your soda in the freezer for too long as it may cause explosions or turn into a slushy mess.


Leaving soda in the freezer can be dangerous because it can cause the cans to explode. The pressure inside the freezer increases and puts too much pressure on the cans, making them burst.

It’s important to consume soda before it freezes completely to avoid any accidents. So, next time you want a cold soda, make sure not to leave it in the freezer for too long!
