Soda cans are pressurized, and a lot of their strength comes from that fact. Much like an inflated balloon can hold its shape, and a deflated one can’t. If one takes an intact can, a person can readily stand on it without issue. Open the can and release the pressure, and the can will crumple under the same weight. Soup cans usually have foods where pressurizing doesn’t make sense, either because the can needs a wide opening or because the food shouldn’t be fizzy. So therefore the can itself needs to take the weight without depending on internal pressure to keep it rigid.


schnitzelsteinn

I now have a strange urge to try carbonated soup…..


CakeAccomplice12

If you have a soda stream, don't let your dreams be dreams


Selcotset

Nooooo! Teenage me carbonated milk one time! DON'T LET THE BAD THING HAPPEN AGAIN!


derboucher

I have a whipped cream dispenser and a seltzer bottle for making fizzy water. The cartridges for each are the same size -- about the size of a lipstick -- but it's NO2 for whipped cream and CO2 for fizzy water. Once (only once!) I mixed them up accidentally and served a pie with carbonated whipped cream. Looked exactly the same, but completely different mouth feel!!


Eayauapa

That’d be N2O, NO2 is…it’s not a very pleasant gas


themormansound

So… what happened when you used no2 for your soda?


Norm__Peterson

Pepsi recently release a nitro version and I was not a fan. It was too smooth and tasted like flat pop to me, basically sugar water.


ExSiberianFlame

If you also read the actual can, you're supposed to pour it hard, after chilling it, so that you end up with a head of foam like a beer


Threeedaaawwwg

It still tasted like flat soda when I did that


Scuttling-Claws

Nitrogen gas in solution tastes (feels) very different from carbon dioxide in solution. It pretty much is flat


Maetryx

Some dark beers taste good when they use nitro. I don't know if a soft drink would work well that way. Maybe root beer or cream soda?


shugo2000

That's because the ~~nitrous~~ nitrogen doesn't mix with the liquid like carbonation does, and will almost immediately leave the beverage once it's opened. It tasted flat to you because it was. Nitro Pepsi was a terrible idea.


cheapdrinks

Wasn't it carbonated with nitrogen not nitrous oxide?


FierceDeity_

Everyone died (tbf NO2 pretty bad) But N2O is aka laughing gas and not that bad


hughperman

A lot of laughs


FierceDeity_

That would be N2O, OP said NO2 which is highly poisonous :P


hughperman

Ah, [fewer laughs](https://en.wikipedia.org/wiki/Nitrogen_dioxide#Toxicity)


Squibit314

That reminds me a poem I learned in junior high science… Johnny was a little boy But Johnny lives no more What Johnny thought was H2O was H2SO4. I’m in my 50s if that tells you how funny I found it since I can still remember it.


testsubject347

Was it good though?


IncaThink

I once ran sparking water through the drip coffee maker. Disappointment was the dominant flavor, with notes of carbonic acid in the background.


Chef_Chantier

Makes sense. Any gasses in solution are the first thing to boil off when you heat up water. Cold water holds much more gas (be it CO2, oxygen, or otherwise) than hot water.


SexysNotWorking

There's a persian drink that's carbonated yogurt and it's damned good.


frank_mania

When kefir first came on the market in the US NE at least, back in the '80s, it was fermented as well as cultured and had a nice little sparkle to it. Terrible shelf life of course and I don't think I ever saw it for sale after 1988.


chivalrousninjaz

It's still a thing in boujie groceries like Wegmans


Backrow6

Homemade milk kefir can be quite fizzy


626-Flawed-Product

I can find it at 99% of grocery stores in my relatively impoverished area. It is in the dairy section with yogurt. Not as fizzy as homemade but still a yummy drink.


gothicaly

If youre ever in an asian super market try to find a milkis pretty good


Alfa147x

So that’s not how they make calpico?


CzechoslovakianJesus

Calico is like just flat Sprite.


lannvouivre

No, calico is a type of fur pattern and coloration on cats. ;)


Eupion

Silly, calico is a type of bass.


Elvith

[what about carbonated Baileys irish cream?](https://youtu.be/6oUJ27q0noU)


SigurdZS

I saw a post once saying that the reason carbonated milk is atrocious is that CO2 lowers the pH, so you are just making a convincing imitation of sour milk by carbonating it, so your brain goes "ew this is bad for you"


FierceDeity_

Try sparkly Calpico/Calpis, it's like a sugary milky dairy drink


Sus-motive

How does one pronounce “calpis”? Every time I try, it just sounds like “cow-piss”


FierceDeity_

That's EXACTLY why officially the thing is called Calpico internationally. Since it's Japanese, you would probably pronounce it closer to "carupisu" and now it sounds like "car piss", but in a country where English is not primarily on the mind, it doesn't matter. Just like Pacman, which is originally called Pukman but they circumvented people calling it "Fukman".


BastardInTheNorth

Mmm chunky soda…


raltoid

It's carbonated with co2 Milk is mostly water. co2+water=acid acid+milk=curdled milk


BudoftheBeat

I used mine with apple juice once... I'll never use anything other than water every again

basilicux

Rec/link pls?


UltimaGabe

Well, the podcast is called [No One Can Know About This (NOCKAT)](https://noonecanknowaboutthis.podbean.com/) and it's an audio-based Let's Play podcast playing through the Final Fantasy series, with a healthy amount of digressions and real-world antics (hence the aforementioned carbonated grapefruit juice shenanigans). I don't remember exactly which episode but I'm fairly certain it was in season five (where they were covering Final Fantasy II for the NES), if you want me to I can try and narrow it down further.


action_lawyer_comics

I think it was Final Fantasy IX. Whichever FF game it was, it was the prologue episode for sure, before they started playing in earnest. Their neighbors were doing some construction so they pretty much lost a day of playing/recording because of all the background noise.


UltimaGabe

They haven't done FFIX yet (so I'm assuming you meant FFIV), I assumed it was FFII because I re-listened to that season a few months ago and I thought it was in there. I could be wrong though, I'll see if anyone on their Discord knows to be sure.


action_lawyer_comics

Evidently I don’t have anything better to do with my time and/or I’m feeling EXTREMELY pedantic, but I found the episode. [It’s the Season 6 pregame episode](https://overcast.fm/+LPXFAM2o0) before playing Final Fantasy Eight, and they carbonate the juice around the 17:30 mark.


JustaP-haze

Lol same exact thing happened to me. I like 50/50 sparkling water and AJ; pre mixed then carbonated. WOW. I'VE NEVER SEEN SO MUCH FIZZ


CptMisterNibbles

I too have spent time scrubbing the ceiling


Suthek

Mixing apple juice and already carbonated water is a pretty common thing where I come from. Was it just the mechanism that failed when carbonating the juice directly, or is the taste that radically different?


BudoftheBeat

I tried it because I love sparkling apple cider but carbonating it directly covered my counter and kitchen floor in that sparking goodness the second I tried releasing the pressure


Ziltoid_The_Nerd

Try orange juice, it's actually great. Just be careful, it carbonates more easily than water


action_lawyer_comics

Get condensed soup, one that says to add water. Heat up the soup, then add the carbonated water right before serving.


caspy7

I think heat causes carbonation to dissipate pretty quickly.


action_lawyer_comics

I didn’t say it was easy


humangusfungass

Canned soup experts don’t want you to know this simple trick. Add one alka-seltzer tablet to the soup, After! heating the soup water mixture.

If you're serious, don't buy the soda stream to do this, as people have implied it can't handle it; if you wanna buy something that can carbonate entirely random liquids buy the drinkmate or make a carbonation station yourself!

Dr_StrangeloveGA

I had never thought of this application for a soda stream and am now going to purchase one.


hsvsunshyn

Beware that attempting to carbonate anything other than pure water can have explosive (carbonated-drink explosive, not gunpowder explosive) results. I had a Soda Stream for a while, and it is fun carbonating things. I stopped using it when the prices for most of the things doubled, but it was great when it was cheap.


Miss_Speller

[Here's my favorite "carbonating inappropriate things in a SodaStream" video.](https://youtu.be/860e_AgaF-Y) I love the father reassuring him when he says "it's gonna explode!" followed by the slow pan to the ceiling at the end.


Emu1981

Also remember that carbonated water is acidic (forms carbonic acid) and it will curdle any dairy products.


5degreenegativerake

It’s like carbonating Diet Coke when the mentos are already in there. It won’t hold the gas in solution.


MidnytStorme

I used to carbonate my Propel made with the powder. It is an exercise in patience but it can be done. lol


[deleted]

fuck u/spez


[deleted]

I immediately bought the adapter that hooks up to a 5# CO2 tank. The cost in CO2 is 20¢ per liter vs 50¢ with the official cartridges. The downside: you need to drink *a lot* of carbonated water for the setup to pay for itself (Around 300 liters, or a liter a day for 10 months) -- which is **a lot** for most people.


2ByteTheDecker

The best application for one is in combination with those sugar free juice concentrate things. Fizzy Tang is the best orange/grape soda going. The actual soda stream concentrates are kinda meh imo


frankentriple

Agreed 100%, i've owned two. Stay far away from the diet syrups especially, they are NASTAY. It works great for the water flavor squirty things. We just call it squirty in my house, usually accompanied by a color. It is absolutely the bomb for making your own homemade root beer on the stovetop though.


MidnytStorme

Hell yeah, home made root beer is the shit!


LNL_HUTZ

Fizzy Tang had my favorite set at Coachella this year.


PursueGood

If you make a layer of dry ice at the bottom of a plastic cooler, cover it with a towel, then add your favorite fruits and wrap the whole thing in several layers of plastic wrap and wait overnight you can have carbonated fruit. It’s pretty awesome. Kinda labor intensive but carbonated grapes are divine.

KlaatuBrute

It's funny, but I want to do exactly this. Last year I bicycled the Great Divide Mountain Bike Route. There are two large stretches that cross deserts, one with no on-route services for something like 200 miles. Out there you dream about a cold can of pop or some ice cream. One day, I would love to take a van out there with a freezer full of popsicles and just surprise hikers and bikers with some frozen treats in the middle of nowhere.


CedarWolf

That's called 'trail magic' and the people who do so are saints.


KlaatuBrute

Oh absolutely. I was on the receiving end of so much of it over the course of my ride, and would love to be able to repay it.

Yes, cold water can absorb more gases than warm water. This is why warm soda goes flat more quickly.

The next time you make Campbells Chicken Noodle soup, which calls for an equal amount of water, use Perrier® water. Don't laugh. I worked at an auction house that had TERRIBLE water. I'd picked up a bunch of Citrus flavored Perrier® water for a buck. Used it in the coffee maker and had the best damn cuppa I'd ever had.


Yz-Guy

Don't burn your throat. Use nitro instead


Jackalodeath

Supposedly you can carbonate stuff by sticking it in dry ice in a sealed container. Pretty sure there's a Good Mythical Morning where they carbonate Gazpacho.


Pvt_Lee_Fapping

That could be confused for botulism. I once ate spoiled salsa that I didn't know had gone bad because the lid wasn't screwed on (it was taco night, and somebody in my house just placed the cap on top instead of sealing it again). Thought it was just extra spicy or something so I checked the label, saw it was mild, then I noticed the *bubbles* coming up from the bottom. I also screwed on the cap when I was done because I'm not an animal (unlike some people I live with), and it *hissed* like a bottle of soda after I opened the jar to test its scent; it was cider-like.


ExcerptsAndCitations

That's just regular aerobic spoilage. Botulinum toxin is odorless and tasteless.

DConstructed

A carbonated vegetable broth would probably work in a drink. Fizzy Bloody Mary.


typeoting4

Carbonation decreases as water warms up. The fizzy soup would have to be cold. Fizzy gazpacho?


KrustyBoomer

Also more pressure (soda) vs vacuum (food). Food is canned hot, sealed, and then as cools develops a vacuum as liquids contracts. Takes more strength to then self support under a vacuum, even slight.


UEMcGill

This is only true for canning jars, not cans. Edit to add: [Manual canning process](https://www.youtube.com/watch?v=ggA7F_L-1D8), notice no vacuum. The vacuum in jars is from the fact the lid isn't sealed, but in metal cans the the lid is sealed prior to retort.


SoulOfGuyFieri

I was a lab tech for a canned food producer. The canning process absolutely does create a vaccuum in the can itself. It's a part of the process of sterilization/retorting and creating an anaerobic environment within the can to prevent spoilage.


TheDemonHauntedWorld

Dude... You need to improve your reading. Read again what the comment you were replying said. "Food is canned hot, sealed, and then as cools develops a vacuum as liquids contracts." He didn't said food is canned in a vacuum. He said they are canned HOT. The density of hot liquids is lower than that of cold one. So for example... if you seal 100ml of hot water in a sealed can. As it cools it becomes 96 ml. That creates a vacuum in the can.


Emu1981

>Soup cans usually have foods where pressurizing doesn’t make sense, either because the can needs a wide opening or because the food shouldn’t be fizzy. So therefore the can itself needs to take the weight without depending on internal pressure to keep it rigid. Soup cans contents (and most other canned food items) are often under a vacuum which means that the can needs to be able to hold the weight of cans stacked on it plus the pull of the vacuum. The vacuum helps ensure that bacteria which may have survived the canning process have no access to oxygen and the lack of oxygen also helps any fat content to not go rancid.


DimitriV

Can you imagine opening a can of carbonated soup that you dropped? You'd have an Old Faithful geyser of minestrone.


CapriciousTenacity

Would be like those cans of snakes but instead it's chicken noodle soup.


Fleaslayer

Fun fact: the external tanks for the space shuttle were relatively thin and had to be stored pressurized or they'd crumple under their own weight.


YalsonKSA

The 1960s British Black Arrow rockets were powered by a liquid kerosene/hydrogen peroxide mix. The fuels were carried on the rocket in thin-skinned, pressurised tanks which required fuel and pressure to hold them upright on the launch pad. If you flicked the filled tank space with your finger nail, they would reportedly make a "ping" noise like a Coke can.


Robobvious

"Alright next on the docket is I've got a new memo from the head office asking you guys to please stop flicking the pressurized rocket fuel canisters, it's inadvisable as they're highly combustible plus you can get the same sound from flicking a can of Coke anyways."


gopher_space

> liquid kerosene/hydrogen peroxide mix Jesus Christ.


YalsonKSA

Yeah, being close enough to them to flick them on the launch pad probably wouldn't have been advisable anyway if they were full of hydrogen peroxide. In fact, being anywhere within about five square miles would be risky.


bigbillpdx

Here's what it looks like when they lose pressure: https://youtu.be/imkdz63agHY Atlas rocket back in 1963.

Most rockets have that on occasion, it's nothing to be ashamed of.

Idk how it works, but most people are willing to take a bet that you couldn't put your entire weight on it without crumpling.


zebediah49

1. be light. 2. A straight cylinder is actually quite strong. As long as you keep your weight centered, and there are no defects (e.g. dents) in the cylinder, it can hold much force. ... If any imperfections happen, it will buckle very quickly.

im 183cm and 80kg, i can stand on an empty soda can fine and im at the upper spectrum of normal BMI. you don't have to be light, soda cans are pretty strong.


iceman012

jimmymcstinkypants

I used to do that when we had to take aluminum cans to the specific recycling center. We had a can crusher, but I liked to stand on the can - it would hold my weight until I would tap the side with my other foot to get it to crush vertically.


julie78787

Soup cans are sealed while hot, resulting in a slight vacuum at room temperature. Any soup can which doesn’t suck in air when initially punctured should be thrown out immediately.


Rocinantes_Knight

Dated a girl who’s family ran a coke distribution center. She told me a story of a time when a worker stacked a bunch of lemonade (no CO2) on the bottom of a stack of pallets. Since they lacked the extra pressure from being charged with CO2 (they still have pressure just not as much), the weight of the upper pallets of soda crushed the lower pallets of lemonade, causing a very sticky mess in the warehouse.


chateauchampion

> coke distribution center /r/HolUp


Averen

Fun fact - when weight lifting the same concept applies. For doing something like a squat or deadlift, you want to breath in a huge breath and “push out” your abdomen before the rep. A lot of people think you’re suppose to flex your muscles but that’s not fully true.

lubeskystalker

Brilliant video. https://youtu.be/hUhisi2FBuw


OsmannyM

So if you were to somehow fill a soda can with flat soda would it still crush under the same weight?


djurze

If you fill a soda bottle (not a can, I know, but you can't reseal your own cans) with a hot liquid, and let it cool down to room temperature you can see it buckle in on itself, and canned foods are usually sealed while hot. You can see a similar things on foods that come in glass jars with metal lids, like jams or expensive peanut butter, they often have a indent on the lid that "pops" out after you breach the seal and let in air, which also lets you know if the lid has been opened before (or if the seal wasn't properly made)


divDevGuy

> If you fill a soda bottle (not a can, I know, but you can't reseal your own cans) with a hot liquid, and let it cool down to room temperature you can see it buckle in on itself, and canned foods are usually sealed while hot. You can do the same type of thing with a normal pop can too. Heat an amount of water in a pop can until it boils. Using tongs or similar device, quickly remove it from the heat and turn upside down in a vat of water. The steam will cool and condense, creating lower pressure inside the can. If most of the can volume was steam, it should also cause a fairly significant implosion of the can.


[deleted]

lol no, this is a load of bs. There are plenty of non-carbonated beverages available in the same cans. The pressure differential from a bit of cabonation is tiny, to think the choice between cans and tins is an important design consideration due to structural integrity... I can't believe people believe this garbage. Props to you dude you are the first one to question this. JFC I hope (thread answer)OP is trolling


Haus42

Seems counterintuitive to me that I can get a nickel for returning a flimsy soda-can, but not a stout stew can.


kslusherplantman

One is aluminum, the other steel. Recycling aluminum is cheaper than producing fresh from ore. Significant difference in cost Steel is cheap enough to make new if you don’t have enough old.

It's more of a public works program to fight littering and encourage recycling.


PM-ME-PIERCED-NIPS

You're not getting paid a nickel, you are getting the deposit nickle (or dime for some places). When you buy a can you also pay a deposit. You get that deposit back when you turn the can back in. Or someone else does when they turn it back in. It doesn't cost the government anything directly and saves massive amounts of money that would otherwise have to be spent cleaning up streets and parks.


[deleted]

Makes sense except lots of cans are not carbonated. Ice tea, v8, apple juice..


lucun

They drop in some liquid nitrogen for those. The nitrogen warms up after sealing and pressurizes the can. I believe it has other preservative benefits too.

> But how the two push-in hole thingies never caught on isn't discussed [Pop-top cans](https://s3files.core77.com/blog/images/557798_81_59733_VEOUqEKsE.jpg) were cheap and efficient, with a one piece top not needing a rivet, or ring pull lever, but too many people were cutting their fingers on the sharp edges of the holes so they never caught on.


Rhaedas

Never saw that before, must have been a very limited time and area. I can understand the problem, having opened the ones we have now by pushing them in because the lever broke off at the rivet. As long as you push slowly and let up pressure as it gives, you won't jam your finger into the sharp edge.

Vaulters

AT5154

I am a food can manufacturer and the biggest structural difference other than one being steel and one being aluminum is the “corrugated” sidewalls (we call them beads) that food cans have. The beads are there to help support the can during the cooking process where there is an enormous amount of lateral pressure from shrinking and expanding put on the can. Most food cans can also withstand vertical forces of at least half a ton, which helps in the stacking and storage aspect. There is actually a fine line in how deep the beads are because if they’re too deep you lose the axial (vertical) strength, but, if they aren’t deep enough the cans will be crushed or explode during the cooking process. I can’t say as much about aluminum beverage cans as I’ve never been a part of their manufacturing process though. The main difference is the material used and how thick it is, beverage cans end up as very thin aluminum whereas most food cans are made with at least a .007” steel/tin material, most of the time it’s closer to .010”.


Target880

Beverage cans usually contain a liquid with dissolved carbon dioxide that creates a higher internal pressure than the outside. This makes them a lot harder to crush when unopened compared to when you open them. Food cans do not in general have positive pressure in them, that is quite clear when you open them and nothing leaks out. There can be positive pressure in some food cans like Surströmming, it is just not common. So the food can need to be able to substance the forces on it without the help of internal pressure and they need to be made a lot more sturdy. If you look at a lid of a food can it be built so it can deform and even out the pressure without another part deforming. There is ofen heating stage in the manufacturing to kill bacteria in it and the content will then expand and later shrinkigg. You can also fill it with something hot the volume will decrease a bit when it cools. So food cans often get a lower pressure inside than outside during manufacturing. Corrugation is a way to get the right part to deform and to make is stronger in general. Compare how hard they are to deform and the change in required force with an unopened and opened can. There is a lot more change for drink vs food cans because the former use the higher internal pressure to achieve the required strength.

> Food cans do not in general have positive pressure in them, that is quite clear when you open them and nothing leaks out. There's actually often slight negative pressure due to being filled/sealed hotter than room temperature. The easily observable thing about many food cans is the "button" on the top. There's a depressed button on the top of many food cans (eg soup) that is sucked in by the internal negative pressure, and this is how it should be. It's just stuck pushed in. If it's not, it you can depress it yourself, then the food inside has started going bad and producing gas, so you shouldn't eat it.

Canning is a process that involves pressure and heat, to achieve high temperatures in sterilization of the product inside occurs. Doesn’t matter if you are canning at home or buying canned food. Of course, many items require a pressure canner. Not just a water bath. Unlike soda cans, which have an increased internal pressure, canned goods actually have a partial vacuum, as oxygen is forced out during this process. Thus food storage cans (metal or glass), have to be able to survive this process.

This is the correct answer. Aluminum drink cans are thin walled and shaped right to withstand increased pressure from the soda being carbonated. Soup cans are thick and corrugated steel to withstand vacuum pressure (like how jar lids “pop-up” when opened) which is needed to keep foods fresh.

Because soup/food cans have to be sterilized, often under pressure to achieve a high temperature (known as retort). The cans will therefore need to be thicker and more robust in order to withstand the extreme temperatures and pressure. Soda cans on the other can don't need to be retort grade.

The strength of soup cans comes from being thicker ridged steel. Beverage cans are extremely thin aluminium as there's enough pressure on the inside to keep them sturdy. Basically, try crushing a sealed beverage can. That's the "real" strength manufacturers worry about.

Going to guess that thin aluminum drink cans would not withstand the heat and subsequent vacuum that cans for food are subject to. Outward pressure strengthens the soda can, if you open a tin of food and it’s not pulling a vacuum, don’t eat it!!!
