Can beer explode when left in the freezer?


Recommended Posts

Slightly off topic, but this reminds me of that Simpsons episode when Bart shakes up Homer's beer as a Aprils fools joke :laugh: ...

:rofl:

(if only I could remember the quote from that episode :blush: )

I once put a few pints up in the freezer as I was expecting a few friends over. They came, we had a few, and I believe we were done early so one bottle was still up there and I forgot all about it. The next morning my mom opened the freezer and the bottle cracked and sprayed stuff all around. No one was hurt, but now I always make sure I don't leave anything up there for longer than it should be!

my girlfriend got a 6 pack of those little mini pepsi cans when they first came out here.. and she brought them home and stuck them in the window sill and opened the window (it was winter) around 3am we heard several very loud bang noises.. sounded like gun shots... she rolled over and turned the light on and 3 of the cans had exploded burst... shrapnel and all.. and pepsi was all of the room... all over the walls and ceiling.. she tried grabbing the remaining cans.. and 2 blew up when she touched them... it scared the living crap outta me!! i've never seen anything like this.... seemed dangerous.. anyone else ever see this????

well uhm, the bootle contains a sparkling liquid. liquids expand about 10%+ if they freeze. the bottle won't explode tho, it'll make plop and break into pieces.

Most liquids do NOT expand when frozen. Things become more dense when they make the phase changes gas>liquid>solid.

Fortunately water doesn't do this, because otherwise life as we know it couldn't exist.

Here's the technical explaination:

Taking water for an example, its density is exactly 1. However the density of ice is around 0.8 because of air bubbles that get trapped during the freezing process.

Absolutely wonderful explanation, just a shame it's completely wrong.

"Taking water for an example, its density is exactly 1." - doesn't mean anything.

Water's density depends on its temperature and the surrounding pressure. Also density is requires a unit, which you didn't even supply.

" However the density of ice is around 0.8 because of air bubbles that get trapped during the freezing process. " - err, no. Ice is less dense than water because of its crystalline structure, nothing to do with air bubbles.

How do people get these silly misconceptions?!

Beer can spontaniously explode if shook, espically when freshly bottled where its cooling. it may expand and crack/explode the bottle. The only way I Could see it exploding is if you violently shook it and threw it in the freezer (placed it in the freezer) and your freezer was like -14C.

Exactly. A lake of beer would not make a good skating rink.

I'm not sure what kind of freezers you guys have, but me thinks their a bit too cold. I used to stash my own beers in the freezer when we'd have parties to keep people from finding them. The alcohol in beer keeps it from freezing, it has to be pretty cold for it to happen, and only because beer has a very low % of alcohol in it. Wine and hard liquor will never freeze in your freezer (trust me, my roommates tried making wine pops one time :rolleyes:)

i jus tasked my sister. she works as chemistristness (sp? whatever) and she told me the expanding volume of the water/beer is being compensated by the little air in the bottleneck and the shrinking/decrease of the % volume of the sparkling gas.

I find that even if it doesn't look like a bottle is frozen, as soon as you open it and release the pressure slush begins to form...

That would certainly compensate for the initial expansion due to freezing, but eventually the bottle would crack if the beer (water, soda) continued to expand.

I find that even if it doesn't look like a bottle is frozen, as soon as you open it and release the pressure slush begins to form...

The gases present become less soluble at the lower temperature, but are initially held in by the pressure of the sealed bottle. Open the bottle and they simply come rushing out, dragging liquid and solid with them.

Well, whenever my dad put is in the freezer he always forgot about them. SO yeah, i saw what happens to beer when left in the freezer. I didnt see it explode mind you, but the pressure from the frozen liquids as they try to expand in the bottle, break the glass (yadda yadda, ppl already explained that) But anyway, cleaning it out of the ice tray maker was a pain so dont forget it in there for too long @_@ if you do (and its not all shattered), just put it in the sink to unthaw for a bit lol :happy:

    • I agree, especially if it is cloud sourced, like this one is.. but I wouldn't say no to a local AI assistant similar to the Zettlab one which would be really helpful with my large Photos library, but also to perform tasks like installing Docker apps rather than me having to do it via Docker Compose, but I don't think we're quite there yet. Synology Photos is somewhat AI, you can ask it to search for certain people (if you have tagged them and it will attempt to match similar photos to the person) and if you put a search term in for "cars" for example, it will show you all photos with a car.
    • I doubt that Google will keep the same price... it may go up from that list published.
    • Sennheiser's audiophile grade HD 600 hits lowest ever price on Amazon Prime Day 2026 by Sayan Sen If you are in the market for high-quality audiophile-grade over-ear headphones then Sennheiser's HD 600 are a great choice for sure, especially today on Prime Day 2026 as the product has hit its lowest ever price (purchase link under the specs table down below). The Sennheiser HD 600 has long been regarded as a reference headphone for listeners seeking a detailed and natural listening experience. It is an open-back design that is built around the idea of acoustic transparency which is essentially said to allow sound waves to move freely for a more spacious and accurate presentation by reducing turbulence and the type of distortion that can result from it. At the heart of the product is Sennheiser’s proprietary driver system featuring a 42 mm driver paired with a lightweight diaphragm and aluminum voice coils. The company says this design helps deliver fast response times and better articulate sound across the audible frequency range. Comfort and durability are also key aspects of the HD 600 as the headphones feature soft velour ear pads designed for extended listening sessions. The HD 600 comes with a detachable 3-meter cable, a 6.3 mm stereo connector, and a 3.5 mm adapter for compatibility with a wide range of audio equipment. The technical specs of the Sennheiser HD 600 are given in the table below: Specification Value Transducer Principle Dynamic, Open-Back Ear Coupling Circumaural (Over-Ear) Frequency Response 12 Hz – 40,500 Hz Sound Pressure Level (SPL) 97 dB (1 V) Impedance 300 Ω Total Harmonic Distortion (THD) < 0.1% (1 kHz, 1 V) Cable Length 3 m (9.8 ft) Connector 3.5 mm Stereo Jack Plug Included Adapter 6.3 mm (1/4") Stereo Jack Adapter Weight 260 g Magnetic Field Strength 1.8 mT Driver Size 42 mm Dynamic Driver Diaphragm Size 38 mm Get it at the link below: Sennheiser HD 600: $237.00 (Sold by Electronics Expo, Shipped by Amazon US) (Was: $449.95) Good to know This Amazon deal is U.S. specific, and not available in other regions unless specified.
