The beer bottle sounds more interesting (Score: 2, Interesting) by email@example.com on 2015-02-01 05:06 (#2WVJ) The wine bottle with a plastic bladder sounds much like existing cardboard containers, except that it's a cillinder instead of a block. Maybe the shape helps break into the mid-price segment (the author who claims $15 wine is for "chugging" must live in a different world), but it's not a big step in my eyes.The beer bottle on the other hand, without the plastic bladder, is actually a step forward in terms of recycling: while cardboard and plastic can be recycled when separated, that is not possible or worthwhile when they are joined together, as far as I know.

How about an aluminium bladder in cardboard?

How about an aluminium bladder in cardboard?I'll bite. How on earth would you make an aluminum "bladder" that is both flexible and durable? If what you mean is aluminized LINING and not a bladder at all, I direct your attention to the fact that aluminum cans are internally coated with a plastic substance as it is. There has to be a good reason for that.

Let a tooth or something else full of calcium soak in a glass of Coke or Pepsi for 24 hours, and note how much of it is left.
