On a warm summer day, there’s regularly nothing far better than ice-cold soda pop. But if you forgot to throw your recent batch in the fridge and also need to cool it under in a hurry, you might take into consideration putting a can of soda in your freezer.

You are watching: How long to put soda in freezer

After all, your freezer is chillier than your refrigerator, and cooling the this way method you don’t need to water the soda down with a chunk of ice.

So what wake up if you leaving soda in the freezer?

There space two feasible outcomes if girlfriend leave your drink in the freeze: you can have a frozen container of soda if you are really lucky. But in plenty of cases, you’ll have actually an exploded can of soda decorating her icebox.

A can of soda that has just exploded will certainly sound a loud “pop” and leave the interior of the icebox coated in snowy soda remnants, together with shards that the aluminum deserve to or plastic bottle.

This occurs as result of the unique chemical nature of water mixing explosively through the normally expansive properties of carbon dioxide gas.

Other liquids can be safely save on computer in her freezer to come to be chilled and frozen into a heavy state, yet not soda. Both water and carbon dioxide have actually a tendency to push against their containers under the right circumstances.

Even if the deserve to of soda hasn’t exploded, it’s no a an extremely safe thing to handle because putting press on the container could cause the very same chain reaction described above.

Overall, putting soda in the freezer isn’t a clever idea also if you’re desperate because that a cool drink.

While it’s tempting to usage your freezer come chill a deserve to of soda top top a warm day, there are other techniques that can achieve the exact same goal there is no as lot risk to your icebox or personal safety.

Expansion of Water In your Soda Can

To completely understand this process, you have to understand how water increases when the ambient temperature transforms with her soda.

Generally, chemistry and physics dictate that chillier temperatures reason the fluid to contract and also warmer temperatures reason the liquid to expand.

This is because greater temperatures cause liquids to become more gaseous together a an outcome of much more energy in the environment surrounding the liquid.

The reverse is true for cooler temperatures; liquid molecules slow down and thus become much more solid. In fact, once liquids frozen it’s a result of the temperature gift so cold the their molecules don’t move approximately as much.

Water follows this basic trend, however only up to a details point. At 4°C, water stops coming to be denser as it cools down and also instead starts to broaden as the temperature proceeds to decrease.

This quirk that physics is what makes ice take up an ext surface area as soon as frozen than the exact same amount of fluid water, in addition to some wait molecules gift trapped in the latticework the a offered piece the ice.

As friend know, her freezer reaches listed below 4°C. It reaches at the very least 0°C in bespeak to attain the freezing allude of water. This way that any fluids included inside your freezer will broaden as they with the last stages of transitioning come a heavy state that matter.

How This influence Soda Cans and also Bottles

So, exactly how does this impact soda cans or bottles and also why go it cause an explosion?

Despite all of the tasty ingredient that comprise a deserve to of Coca-Cola or Pepsi, both beverages and also all other varieties of soda are primarily water and carbon dioxide. In fact, water is the solitary ingredient that makes up the majority of the issue in a offered can of soda.

This means that every have the right to of soda is usually a ticking time bomb if friend stick it right into your freezer. That’s 16 or so ounces of liquid will chill until it get 4°C, then begin to expand.

However, water alone would not cause an explosive effect. The existence of carbon dioxide is the secret ingredient.

You see, as the water expands, it likewise puts press on the carbon dioxide gas come escape that confinement. Unlike consistent water, carbon dioxide is reasonably explosive if girlfriend unleash it easily through a tiny opening.

Imagine opened a can of soda; the instant hiss girlfriend hear is the carbon dioxide escaping through the optimal rapidly. Once a can of soda explodes, it’s since the water and CO2 have put so lot pressure ~ above the can that the structure can’t stand up to it any longer.

The aluminum have the right to of a common soda is solid enough to withstand normal push changes and hold the carbonation push from the carbon dioxide gas.

But it’s not built to take care of the kind of pressure that comes with whole can of fluid trying come expand. As you could imagine, the broadening water has nowhere come go, increasing the stress and anxiety on the aluminum can, particularly its weaker points favor the tab i m sorry you use for opened the soda come drink.

These weak points just become more stressed together the water and CO2 proceed to expand and also reach 0°C. This is no a sudden process; that’s why some cans that soda will certainly actually do it every the method to the freezing allude and come to be frozen solid there is no exploding.

In those cases, the expansion result that happens slowly enough in the aluminum have the right to was strong enough to resist the change.

But in many cases, the slight press buildup will eventually reach a breaking suggest and cause the optimal of the soda can to literally blast off.

In part circumstances, the center of the have the right to may be the weakest point, for this reason this is the spot that will explode outward, sending shards the ice and also aluminum everywhere. It’s fairly a mess.

It’s simple physics; the water and gas within the have the right to expand and the aluminum deserve to isn’t solid enough to keep it contained. Therefore, using a freezer come cool under a deserve to of soda is a risky venture.

Note that this entire procedure is no longer relevant if the deserve to of soda is currently opened. It’s perfect fine to put a cup that uncovered soda into the freezer because there will be enough space for the expanding liquid to accounting without putting a strain on the container.

Can girlfriend Still usage the Freezer come Cool Soda?

As mentioned above, friend can always use the freezer come cool soda if it’s in another container besides the original sealed have the right to or bottle.

Of course, a cup filled come the brim v soda will certainly overflow as the liquid expands, yet it won’t explode and cause as lot of a mess inside the freezer.

You need to pay really close attention as soon as using the freezer to supply a fast burst of cold prior to drinking to protect against dropping the temperature as well much.

The idea is to take it the soda out prior to it get 4°C once the water within the deserve to would start to expand.

Taking the have the right to out before this point will permit you to enjoy cooler soda without risking the explosive effect.

Ideally, you’d want to save a nearby eye ~ above the soda and check the after around 20 minutes. Anything after 20 minutes or so threats the can drop to a temperature listed below 4°C, which can put pressure on the can.

In this case, you need to be mindful when dealing with the have the right to or bottle of soda together disturbing the container could reason a preemptive explosion.

Alternative techniques To Cool her Soda

Instead the risking an exploding deserve to of soda, there are better ways to show your soft drink, and much much more rapidly, to boot.

You could constantly place a have the right to of soda in the refrigerator. The approximately cool temperature inside will slowly change the temperature of your soda, although air is a poor heat conductor and will only achieve this procedure slowly.

By far, the best way to cool down your have the right to of soda is to placed it in a cooler or bath of ice water.

Another exciting property that water is its heat retention. A warm can of soda placed into ice water will easily transfer that warm into the water itself, leaving the deserve to ice cold much more quickly 보다 if girlfriend left the soda in your refrigerator.

Water suck away warm a lot much more efficiently than constant air.

This is partly due to water’s very own chemical properties and also the fact that water is a lot denser repertoire of molecules 보다 ambient air. All of that water deserve to run over the surface of your have the right to of soda, touching an ext of the can than waiting does in less time.

The an ext surface area reached by the ice water, the faster the cooling process takes place. Because water maintain heat really well, over there won’t be lot of a feedback loop, so your can will stay cold quite than suck up warmth that the water bring away on from the environment.

Overall, using an ice bath to cool down a can of soda have to only take it a couple of minutes together opposed come the hours required by a modern-day refrigerator, and also all without the danger of one explosive mess the comes with using a freezer.
