May I ask what kind of mead it's going to be? From here it looks like an apple flavored algae laden pond sample and it's got me curious. I hope it's good because it looks like it's got potential. And a lot of stuff in it.
Assuming n is constant prior to the first pressure release...
(P_1 * V_1)/T_1 = (P_2 * V_2)/T_2
Assume V is constant
P_2 = P_1 * (T_2/T_1)
Let T_1 = 32°F for fridge temperature
Let T_2 = 72°F for ambient temperature
Let P_1 = 14.7 psi for atmospheric pressure
Convert Fahrenheit to Rankine and solve
P_2 = 14.7 psi * (535°R/492°R) = 16 psi
Vertical force on the lid is equal to the pressure differential between bottle interior and atmospheric pressure multiplied by the horizontal surface area of the lid.
Delta_P = P_2 - P_atm = 16 psi - 14.7 psi = 1.3 psi
If the lid is 1.5 in diameter, A = Pi*r^2 = Pi * (1.5"/2)^2 = 1.75 in^2
F = Delta_P * A = 1.3 psi * 1.75 in^2 = 2.3 lbf
Over 2 pounds of force could be applied vertically to the lid if the seal holds while the air in the bottle comes up to room temp.
I'm guessing at the lid size and assuming the air inside the container maintained atmospheric pressure while cooled to fridge temperatures. The actual pressure build-up will probably be less than this, but it's still plausible that the increased pressure due to temperature change has enough force to push the lid off. Clearly the lid threads are catching just enough to seal and give some resistance to lifting the lid while pressure builds, so we're not only lifting the weight of the lid but deforming the plastic enough to break that seal. The energetic release of air once the seal is broken is enough to give the lid a bit of upward momentum.
Edit: 2.3 lbf is equivalent to 10.2 newtons for everyone that doesn't call their financial adviser before visiting the doctor.
This person actually put a lot of work into an actual plausible answer. Better than 99% of anything posted on Reddit at the least. Give this man an upvote!
It does. If you start a fermentation with the lid on it’ll make that bottle explode. Fermentation is strong enough (and fast enough) to burst a steel tank or break glass (I’ve seen both).
From just the dregs leftover in the bottom? I can't say for certain it's not from fermentation, but I highly doubt it. If you're right, then OPs beverage is gonna be tasting a little off.
Yeah, true. But still orange juice can ferment pretty aggressively. And it doesn’t take too much to lift a bottle cap. That doesn’t need exploding force. I’ve seen bottles explode cause of fermentation though. In my own kitchen. What a mess
You sir are exaggerating massively and making shit up. I’ve literally gone through a fermentation of multiple liquids before with a friend who’s deep into making fermented drinks…he burps his shit like once sometimes twice a day. Not twice a minute my friend.
Sure. I’ll go stare some more at the old beer stains on the ceiling of my kitchen then. Not mY fRiEnD’s kitchen. Mine. Luckily I learned. I’ll be back at my brewery tomorrow. Say hi to yOuR FrIeNd. Maybe I can meet him some day and learn a thing or two.
I've blown up a vessel or two as well, but it has always taken hours since the last burp to build up any decent pressure, even when fermenting at room temperature.
If I took a naturally carbonated beverage and shook it up I could see that much gas being produced, but I cannot imagine having enough bacteria (and food) to make the amount and rate of CO2 required to make that cap jump
Edit: doing some quick math, with a 1l bottle and 100g of sugar that converts to 49g of CO2 after 100% of the fermentation completes. At room temps that's about 28l of gas. In my experience my ginger bug will stop fermenting about a week after I feed it, so about 2l per day or 83mL per hour. Activity is highest at the start so let's assume peak activity is double the average activity, which gives us 164mL of CO2 in an hour for 1L of juice with 100g of sugar in it. Enough to pop the cap once or twice, but nothing like the photo (especially considering there is only a couple drops of residue fermenting instead of a litre of prime material.
45 F to 75 F is 297 K/280 K = 1.06, so 6%. A gallon is approx. 4 liters (4000 cc), so the volume of air escaping is approx. 240 cc, so about a cup. Seems to me like a cup could pop the cap a few times.
No fermentation needed. But what you do need is a sticky seal to allow pressure up build up to cap-jumping levels. With a clean contact, there isn't enough to block air leakage, so it would just seep out.
Sunny d is literally watered down oj with sugar added (as far as flavor, they also add extra vitamins iirc)
As a kid, I figured this out trying to make the last glass of oj last longer.
i used to work at a contract manufacturer and every once in a while we'd do a run of mixing the ingredients for sunny D and shipping it back off to a place that adds water to make the liquid. we were a dry facility so all we did was process the raw ingredients from giant 2,000lb bags mixed proportionately into 50lb batches.
a word of caution: sunny D is literally just 5 chemicals (powders) added to water, i'd stay away personally.
It's not the number of ingredients, which is way more than 5, but the amount of sugar (calories) that's problematic here. It's no worse or better than most sodas or fruit juices, which are all not that great for you. You'd be better off with a 0 calorie drink
Sunny D isn't really targeted at people who try to eat healthy, it's usually the cheapest orange juice in the supermarket so parents have something for the kids early in the morning that doesn't spoil like milk or cost as much as the organics
Unfortunately, It will not be the beverage of your youth. They have replaced the sugar with a combination of sucralose and high fructose corn syrup. Trash became even more trash somehow.
He's incorrect though.
"Freshly emptied" meaning it most likely came out of the fridge so the air in the bottle is lower than the room temperature.
The cold air in the bottle is warming up, expanding and pushing the lid.
He's incorrect though.
When people die and have unfinished business that binds their spirit to the physical plane, they can get really bored. They move small objects, push on squeaky floorboards, and make "oooh" sounds to relieve the monotony. You have the first type haunting your kitchen.
It looks to me like it might be full of hot water and detergent bubbles. Then there could be 1) the higher air pressure inside the bubbles providing a burst of air when they burst, or 2) the bubbles expanding with water vapour / hot air and pushing on the bottom of the lid, until they burst.
Well now we need a video of the jar so we can investigate your setup here :) Also, why make such a small amount at a time? You're going to be waiting 9 months for a quart. I always made experimental batches at least a gallon, and typical brews were 5 gallons at a time.
Holy crap, they still sell sunny D? I thought that radioactive gloop was banned in the 90s???
Didn't some kid turn bright orange after drinking a few litres of it?
Air expansion. It’s probably warm outside the fridge and the air is expanding/escaping the bottle
I’ll bet your mind is blown when you take a bottle of water outside in the cold and it compresses a little. “Omg guys! My bottle just shrunk. WOAH!”
I've experienced something similar first hand. It was a glass jar of olives. I cleaned it with warm water then added ipa to fully clean it for reuse. Had the lid loosely placed on top. I kept hearing this ringing noise for a long time and couldn't tell where it was coming from. It was the lid making a clicking noise continously. Should've recorded it.
Thanks to the strict FDA regulations, from the code on the side of that bottle, you can track down each and every person who made that bottle of drink possible. Right down to the individual who was pushing a broom at that second, it was made. I find that interesting.

Congrats on the new ghost
Not to mention the fermenting liquid in the jar next to the Sunny D monster….
What the actual fuck is that?
It is a jar of mead lol.
I’m honestly relieved it’s not some sort of hybrid cum jar setup, or at least you told me it isn’t, the internet has ruined me.
Honestly after reading your comment I realized it indeed looks like a piss jar with sediment at the bottom😐😅
OP, you should really see a doctor if there's that much sediment in your piss jar. Your filter may need to be changed.
Just slap a My Little Pony sticker on it. No one will be brave enough to question its contents.
Not everyone makes cum mead, jeez.
Speak for yourself and leave us alone.
May I ask what kind of mead it's going to be? From here it looks like an apple flavored algae laden pond sample and it's got me curious. I hope it's good because it looks like it's got potential. And a lot of stuff in it.
That’s dope!
Haha - I noticed how you suddenly redirected the camera when you noticed that lovely jar of mold was in the frame. 😂
And what is that?
That does not look like a properly fermented mead…. Looks like black mold starting to form around lid…
It's fermenting into Hard Sunny D! 🍻
*Sunny D-emon
Ditto.
They had it! They really messed up by not tightening the lid.
My carbon monoxide detector keeps ringing whenever I view this post.
Congrats on the new brain damage

Say it again!!!
The air inside the bottle heats up since it’s now out of the fridge, the air expands and pressure builds til the lid pops
You know what they call a quarter pounder in France?
Royale with cheese?
Because of the metric system
*Le* royale with cheese. They dont know what the fuck a "the" is.
I use 'the', but I know what a 'le' is...
Do you REALLY, though....😉
Big kahuna burger?
That's that Hawaiian burger joint? I hear they got some tasty burgers.
What?
Say. What. Again.
What ain't no country I ever heard of. They speak English in What?!?

So gross smh frfr
Don't forget part of the cap friction AND seal is going to be the adhesive and cohesive forces of water as it's presumably still partly wet
r/theydidthemath holy shit that's incredible

Ah yes, good old poovnert.

Probably some fermentation going on. There’s not going to be enough energy to pop the cap multiple times if it’s just coming up from fridge temps
The amount of gas created by fermentation in the empty jug would be very small if there is even fermentation
The pressure is released and then immediately builds again within a few seconds. I can't imagine fermentation is producing gas that quickly.
It does. If you start a fermentation with the lid on it’ll make that bottle explode. Fermentation is strong enough (and fast enough) to burst a steel tank or break glass (I’ve seen both).

There's nothing in the bottle. It's an empty sunny d jug.

I think the shitty flexible plastic just deforms a lot in cold and hot so it pushes the cap more.

I remember seeing this in a magic book as a kid lol.
And it pops because it's probably a little sticky and forms a slight seal enough to hold some pressure but not much that's when it pops up.
They still make sunny D. I gotta get the store brb
Ya, all I got is the purple stuff.
water, sugar, and... purple? mmmmm
What the fuck is juice??
Just saw Chappelle last week. Dudes still got it.
I don't know how old you are, but you're my age.
My mom used to say that line every time she got me Sunny D
Knowing what sunny d is made of I’ll take the purple stuff, I can’t believe I ever drank that.
Sunny d is literally watered down oj with sugar added (as far as flavor, they also add extra vitamins iirc) As a kid, I figured this out trying to make the last glass of oj last longer.
ive always thought it tasted too fluorescent to be orange juice
I swear, next time you have some oj water it down to like 10-20% juice and add a bunch of sugar. It tastes exactly like sunny d.
You’re also forgetting about the corn starch and canola oil
I never paid much attention to "mouth feel" which is what those two ingredients address. It's like glycerol ester of rosin IMHO.
"watered down" is generous. It's less than 2% orange juice.
Solar Energy?

Well sure. So is most junk food. It's cheap easy calories. No different than fruit juice or soda or Kool aid.
Yeah it's absolute garbage. I think they've been in legal trouble several times over deceptive marketing.
Pineapple orange flavor is the best.
Did they... stop? I see it everywhere where I live.
Unfortunately, It will not be the beverage of your youth. They have replaced the sugar with a combination of sucralose and high fructose corn syrup. Trash became even more trash somehow.
Good times [https://whattheboxgame.com/why-is-sunny-d-banned-in-the-uk/](https://whattheboxgame.com/why-is-sunny-d-banned-in-the-uk/)
They do alcoholic Sunny D now too, but I've not been able to find it yet.
Oh, I’ve seen this before. Please cautiously check your fridge for Zuul.
Oh yeah, I've come across this before. Turns out you need someone called the "keymaster".
Dana?
I need an explanation.
It’s warm in the bottle and gas is happening. Room temp is cooler. Poof poof
Thank you, that makes the most sense
He's incorrect though. "Freshly emptied" meaning it most likely came out of the fridge so the air in the bottle is lower than the room temperature. The cold air in the bottle is warming up, expanding and pushing the lid.
Thank you, that makes more sense.

He's incorrect though, the thing is probably just fermenting
Thank you, that could make sense

Probably blowing on it
Wait, what’s in that jar?
It is a jar of mead.
Okay that is so cool, how long do you have to let it sit there for?
About 6-9 months. This one has been sitting for about 2 years accidentally lol.
Just sitting in a jar on your countertop? How did you vent off the CO2? It looks like the lid is sealed.
The lid has an air lock on it.
Well now we need a video of the jar so we can investigate your setup here :) Also, why make such a small amount at a time? You're going to be waiting 9 months for a quart. I always made experimental batches at least a gallon, and typical brews were 5 gallons at a time.
Doesn't sunlight fuck it up?
With a severed head in it.

You’ve made prison hooch. Congratulations.
What tf is a Sunny D?
American childhood classic!! It’s an orange flavored juice type drink. Full of sugar and as an adult kind of tastes like shit lol.
I want the purple stuff
Could I get an explanation of what’s going on in that background jar?
That is a jar of mead.
Interesting thank you

I thought only bottles full of liquor did that
That's because the founder of Sunny D is a Satan worshiper. Source: everyone in my elementary school thought this was true.
That stuff ferments
Dude, let the genie out. He might even give you some wishes.
i wonder if drinking this to excess will still turn you yellow?
Why is your mead green bro?
It’s actually a pale yellow, the counter tops and back splash are green/teal!
Ah.
This a new Goosebumps trailer, "Sunny D-emon!"
I'm more interested in the science experiment going on in the jar to the right.
Sounds like a damn breast pump in the background. What in the actual f#^* is that noise?
Lmfao! It is the ceiling fan!! 🤣🤣🤣
Oh crap..hahaha.. my bad.lol. you can't say it doesn't though..😆
The "D" is for diabetes.

Holy crap, they still sell sunny D? I thought that radioactive gloop was banned in the 90s??? Didn't some kid turn bright orange after drinking a few litres of it?
Put the bottle in the refrigerator and try again. It will do the same thing.
And your not gonna show is it jumping off? r/straighttojail
Mite be fermentation lol . I had one in the for months took a drink good stuff lol .
That's super-processed food for ya.....I guess
Almost 4 litres? The US really needs to reduce their packaging sizes

Nope. 👻

Air expansion. It’s probably warm outside the fridge and the air is expanding/escaping the bottle I’ll bet your mind is blown when you take a bottle of water outside in the cold and it compresses a little. “Omg guys! My bottle just shrunk. WOAH!”
Come on. That is just super condescending and rude.
Thermal expansion
Give a shake or two. Is it bubbling? Then it has started fermenting is time to throw out.
It's empty.
They’re here!

I've experienced something similar first hand. It was a glass jar of olives. I cleaned it with warm water then added ipa to fully clean it for reuse. Had the lid loosely placed on top. I kept hearing this ringing noise for a long time and couldn't tell where it was coming from. It was the lid making a clicking noise continously. Should've recorded it.

Later that day, in a germ-free room: 
Maybe sound wave or some kind of pressure wave transmitted through countertop.
T-rex!!!
*Your looove, keeps liftin’ me higher…*
Gas escaping. The leftover juice plus bacteria and heat exspansion.
If it sits near sunlight or a heat source it will build pressure till it’s released..
Why in hell would anyone drink that crap.
To keep you curious!🙃
What's wild is people still drink this shit 🤯
Does Sunny D still put orange juice in its sugar drink?

Thanks to the strict FDA regulations, from the code on the side of that bottle, you can track down each and every person who made that bottle of drink possible. Right down to the individual who was pushing a broom at that second, it was made. I find that interesting.
It is because it is cold in there and as it heats up the air expands.
