Soda is acidic and comes in Aluminum cans. Why don't the cans develop holes?
- slater 5y ago"The inside of the can is lined by spray coating an epoxy lacquer or polymer to protect the aluminum from being corroded by acidic contents such as carbonated beverages and imparting a metallic taste to the beverage." https://en.wikipedia.org/wiki/Aluminum_can https://en.wikipedia.org/wiki/Aluminum_can
- pleb_nz 5y agoI often wonder how good that coating is for consumers. I'd be surprised if it doesn't leach into the produce.
- Caspy7 5y agoCertainly a belief among some that soda from a glass bottle tastes notably better.
- throwntoday 5y agoThat has more to do with the use of cane sugar vs corn syrup
- boomboomsubban 5y agoMexican Coke, which uses cane sugar, comes in a glass bottle, but you can also get US coke presumably with corn syrup in a glass bottle and some people do think it tastes better.
- ac29 5y ago> Mexican Coke, which uses cane sugar This is at least partially a myth. Here's a study which found no sucrose in Mexican coke: https://onlinelibrary.wiley.com/doi/full/10.1038/oby.2010.255 https://onlinelibrary.wiley.com/doi/full/10.1038/oby.2010.25... Though, it is complicated because there are multiple bottlers making multiple different coke products, and even the same bottlers could shift what sweeteners they use over time, presumably based on pricing.
- Cthulhu_ 5y agoI'll vouch for that when it comes to beer. It's not just the packaging itself though, but also the experience. Plus, when you drink from a can directly, your lips will touch the outside / top aluminium, which will affect the flavor and experience - subtly, but it's there. I prefer glass bottles for my beers.
- markdown 5y ago> when you drink from a can directly, your lips will touch the outside / top aluminium, which will affect the flavor and experience - subtly, but it's there. Ahhh the subtle flavours of rat shit. I've never seen someone wash the top of a can before opening it. I mean, would you go around licking random surfaces that other hands have touched, rodents have scurried over and defecated on, etc?
- hammock 5y agoThe odds that a hand or rat has touched the top of a can you just pulled out of a box is pretty slim

- jusssi 5y agoAs an aside, to me Coke from can has a different feel from Coke from plastic bottle. Almost as if the bubbles are fewer and larger when sipping from a can.
- hammock 5y agoWell the carbonation is different for cans vs bottles, and also dependent on the bottling plant.
- rob74 5y agoThen you should also worry about plastic water bottles...
- coryrc 5y agoDepends on the kind of bottle; polyethylene, safe; polycarbonate, not safe; polyethylene terephthalate, not great.
- hammock 5y agoJust about every disposable water bottle is PET, which is far down the list of dangerous plastics when it comes to leaching (to ignore for a moment microplastics).
- arcticbull 5y agoThe epoxy resin is mostly BPA. [1] [1] https://www.coca-cola.ca/faqs/coca-cola-faqs-health/do-coca-cola-cans-and-bottles-contain-bpa https://www.coca-cola.ca/faqs/coca-cola-faqs-health/do-coca-...
- rob74 5y agoThe article you linked talks mostly about BPA, but the resin only contains it...

- arcticbull 5y agosorry, I didn't mean by volume, but rather that when folks say resin they mean bpa epoxy resin.
- iNerdier 5y agoBecause they’re really a plastic bag with aluminium lining. Nurdrage has a good video showing this: https://m.youtube.com/watch?v=X1pB6O6AYMU https://m.youtube.com/watch?v=X1pB6O6AYMU
- zwirbl 5y agolovely vid and great channel
- rob74 5y agoIf the cans weren't lined (like other commenters remarked), the most the acid in the soda would do is dissolve a little bit of the aluminium - of course that's not necessarily healthy, but to get a hole in the can you'd need something much stronger. Despite what some urban legends claim, there is still a difference between Coca-Cola and hydrochloric acid...
- hammock 5y agoAluminum soda cans are lined with BPA or similar.
