    Just straight up stop buying shit. Drink filtered tap, and live off only what you need and shrug off ppl that think buying expensive shit will make them cool.

      Also stop paying for filtered tap water when there’s nothing wrong with your specific tap water.

        Sadly not everyone has great chlorine-free water. One of the most annoying experiences every time I go abroad (for example to Italy)

          Quite true. Not everyone has lead-free water either. But people whose water is perfectly great do not need to pay for filtered water - especially not in single-use plastic bottles.

            Absolutely. I’m always drinking tap water at home, we have perfectly clear, chlorine-free, mineral-rich water directly from the mountains. One of my favourite aspects of Austria.

          Chlorine is the least of my worries.

          After growing up near a superfund/dump site where benzene, toluene, phthalates, etc. were found in the water….I will take the chlorine.

          I would have been more than happy to drink tap water and have my kids drink tap water.

          We’ve had a couple lead warnings though and I don’t want to fuck with it. They’re going to have a hard enough time with the misfortune of getting my genes. I don’t want to make it even harder for them.

        Where I live has heavy agriculture and oil industry presence. People here are concerned over pesticides and random chemicals randomly seeping into the water system.

        Just a heads up Brita filters do basically nothing it’s mostly just a carbon block which will help remove chlorine flavor which makes it taste a little better but in terms of actually removing contaminants it does very little to almost nothing.

        Zero water is the closest thing in brita drip form that actually removes things but getting a counter top reverse osmosis is the way to go if not getting a dedicated under sink unit

          Just remember! Reverse osmosis filters are NOT eco friendly, it cost 3 to 4 gallons of waste water discard to gain 1 gallon of drinking water.

            Using modern filters, and using a pressure booster pump to ensure proper pressure level this is actually nowhere near as bad it’s now possible to achieve a one-to-one clean to waste ratio.

            If you don’t want any waste you can go to nanofiltration which is roughly as effective as Reverseosmosis and does not have the Wastewater issue but they are significantly more expensive.

            And it’s not as if that Wastewater is sewage it’s just the same water that came in with a higher concentration of the stuff that you didn’t want that was already present in the water so that Wastewater can be reused for gardening, or gray water such as showers and toilets

            I get that they aren’t perfect but everything has a trade off and reverse osmosis or nanofiltration is really the only way to get rid of many different sources of water contamination especially things like microplastics and pfas

    I think this falls under the term “merchandising”, which includes “family size” or “party size” things that cost more per ounce than regular 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?

      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.

            It’s not really ‘right’ or ‘wrong’ it’s under a fixed set of assumptions. You raise a valid point. What does happen to the top and the bottom? I was ignoring them considering only the sides in the two most extreme cases.

            If I understand your case when the can is flatted the area gets much larger and when it gets taller it shrinks to a pin point. An equally valid approach

        It’s far from being that only, check the ingredients (especially if using the zero sugar/calories version)

        Yuka is a great app to tell you this as well, if you’re okay with it

    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.

      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.

    Not only do they cost more, the greater surface area means your cold drink warms up faster.

      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.

      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.

        Weren’t soda companies whining about aluminum costs just recently? Guess they found some extra in order to fleece their customers.

        These are more easily stackable and take up less horizontal space, so they are more efficient for transport.
