You know, this should only trick young kids as they genuinely believe taller = more. The fact that it probably tricks a ton of adults just suggests their critical thinking never made it past adolescence and we should be very concerned by that.
So that's why they changed the shape. I saw no valid reason so I just assumed they were trying to evade taxes in some way. I'll admit I have no idea how much anything I buy at a convenience store costs.
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.
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.
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?
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.
