Oil prices go up - petrol goes up.
Oil prices go down - petrol goes up.
Oil prices do nothing - petrol goes up.
Petrol is purposeful and independent.

Quick ‘proof’ the taller the can, the more material used:
Consider two cases ignoring the top and bottom only focussing on the surface area. In the first case, you flatten so much the can has no height. This forms a ring that when unwrapped makes a length of 2 pi R.
Now stretch the can to be ‘infinitely’ long. By construction, this is longer than 2 pi r. Given both are made of aluminum, and have the same density, the larger can has more mass requiring more material.
The total mass must be a continuous function ranging from the linear mass density times the circumference of the circle to the same mass density time times the ‘length’ of the infinite line. This must remain true for any small increase in length between the two.
I’ll leave this as an exercise to the reader. What if the circle has an infinite radius?
Isn’t the larger the can proportional to how does both top and bottom shrink? like, being the same amount of material, but with a different distribution.
No he’s right. The solution for an optimal surface area to volume ratio is a sphere. The farther you deviate from a sphere the less optimal you become. The actual math for this is finding deltaSurfaceArea in respects to cylinder radius for a given volume and then finding the maxima, which is a Uni physics 1 problem I really don’t feel like doing. Long story short, optimal is when height = diameter, or as close to a sphere as a cylinder can be.
Thanks fot the aclaration.
I mean it sucks and I drink coke (it’s my mix for booze) but it’s a welcome change (price increase). Soda pop should not be drunk as frequently as it is by people and anything to make it less common is a welcome change IMHO. If becoming more cost prohibitive to people makes them drink it less that’s not a bad thing
Now the challenge becomes, because America is becoming a 3rd world shithole it’s possible that coke is the only safe drink because thanks to the EPA being gutted over decades water isn’t safe in many areas due to contamination. That’s not cool.

You know that has a lot of sugar, which is a poison and will kill you right?
Everything will kill you in excess. Live life and don’t be a Debbie Downer.
Hey friend, I’m not the one complaining about the water or people drinking too much.
It’s friday and I’m going to have plenty of drinks, there will be no soda in sight.
I wish you a good weekend.It’s friday and I’m going to have plenty of drinks, there will be no soda in sight.
Um… congratulations?
Um…thank you
I wish you a good weekend too
with or without sodas

Not only do they cost more, the greater surface area means your cold drink warms up faster.
Neat.
Greater surface area also means more material for the same product, which leads to less effective transport, more waste and increased polution. Non-standarized can size means every can storage system and cup holder which have taken can size into consideration will be worse. I’m sure a lot of vending machines will have to be modified or scrapped for this can design.
Everyone are worse off because of this, and it’s all for attempting to trick consumers and increase profits. Shit sucks.
These are more easily stackable and take up less horizontal space, so they are more efficient for transport.
Is this a new thing in the US? We’ve had these in Europe for years - and I mean 10-15 at least.
Hey we get this revolutionary super can which is supposed to keep your beer cool.
The ribs are supposed to reduce the contact area of warm fingers.
It doesn’t work obviously since they aren’t big enough and skin on fingers are flexible enough to touch everything.
You only pay 30 to 50% more for this nonsense.
Everyone tries to avoid them but somehow the normal cans are more than often ‘sold out’ in stores.
That’s what you get for drinking jupiler
I only partake in the finest carapils
Hey Stella snob, it’s not like you always have a choice.
Also it’s standard thirst or get drunk gulping beer, not a fancy trippel or geuze.
Doesn’t really matter that much.
Where is the one on the left no longer available? I live in the US and see those all the time.
Weird what happens when 40% of the currency was printed in the last few years.
Are we blaming the government who control interest rates, gamify the CPI to depress inflation, and who control the corresponding new money supply that drives up the price of basic goods?
If housing, gold, and crypto are any indication people have far too much money than they know what to do with. You’d have to be a fool to not accumulate some cantillon effect for yourself when you’re government is throwing money away.
I’m surprised the new one isn’t something less than 12 ounces.
surely this uses more aluminum
It may use less aluminum, as the top and bottom surfaces are much thicker
I’m shit at math, but probably not? If both contain the same amount of liquid, are filled to the same point and both are round (which they are lol), I don’t see how those would require more material.
And even if, if they double the price per can, it’s absolutely worth it.
You have never taken calculus.
No, that’s what I said with my very first sentence.
Have you? AP calculus doesn’t count.
I found this same thought on this same post a year ago. Someone already crunched the numbers and it seems with the volume constant but height growing, the surface area increases
Original discussion: https://lemmy.world/comment/8371055
A further complication is that the aluminium is considerably thicker on the base and the top… so there’s more thin metal, and less thick metal.
Why don’t we just weigh them?
Shut up with your logic! I’m going to the grocery store…
To illustrate, imagine if we kept getting taller and taller - like trying to fit the same volume of soda in a pencil-thin can that’s about a meter long.
You use more and more aluminum the further away it gets from the minimum surface-area-to-volume container, which would be a sphere
The fuck is a fluid ounce?
Fluid ounce is volume, ounce is weight. Liters vs grams.
Ah wonderful, so I’m sure one fluid ounce of water weighs precisely one ounce weight wise?
Almost identical, my understanding is it’s slightly off since it’s such an old measurement. But for everyday purposes it’s the same.
Common mistake. Its actually Florida ounces.
…two-thirds a dram of scotch whisky…
Damn liberals and their woke-genderized measurements smh
This cannot be a real question.
Because everyone on Reddit is American? Or that the entire planet is supposed to understand nuanced differences between ounces and fluid ounces that only… what, 3 countries on the planet use?
1/8th of a cup
Ounces that are wet.
People with vending machines aren’t going to be happy, those new ones won’t fit.
As a consumer you should have thought about the consequences of your habits. Because of you they now have to replace all the vendig machines.
Its the consumers fault. Companies have absolutely no responsibility.
Huge /S if there ever was any doubt.
A few years back we literally had frito lay vendors come in before store open to reset the chip aisle, all the bag sizes shrank and they credited out the previous size.
I think this falls under the term “merchandising”, which includes “family size” or “party size” things that cost more per ounce than regular size.
Babe, wake up. New shit corpo practice just dropped.
