Anyone noticed that cans have gotten thinner in the last 10 years? Seems like they actually made the process even better. Well, for them, not for me. I've had m

  Definitely different per manufacturer here in Europe. Coke cans have always been thicker than Red Bull for example, like I think in general our 0.25l cans. But yeah, the 0.33l cans have become thinner over the last 20 years, but I can't say if progressively or at some point from A to B. I don't buy cans a lot, but I don't even remember if I ever had a punctured one except when maybe dropping it on concrete...

    I put one (0.33L, btw) in a bag today and it punctured. I was really surprised as I really didn't think it had been under much if any stress.

      They are susceptible primarily to corners, and after that, to edges. The sharper, the worse. The way they are made, and the type of aluminium they are made out of, results in them failing after experiencing comparatively little strain (for being a ductile metal alloy). Because the walls are so thin, squeezing them with the grip of a hand won't cause much strain, due to the large bending radii (seen relative to the wall thickness). But if you concentrate the force around a (comparatively to your fingers) sharp corner/edge, especially if it's a corner sharp enough to hurt if you pressed on it with your hand and, say, ~5kg worth of force, you'll force it to stretch to conform to the pointy corner's shape. (Despite the factory already pushing the material close to it's limit as far as stretching-before-ripping goes. No wonder it rips, then.)
