first of all copper will not "rust" but it does tarnish or corrode, turning a green color when it oxidizes. The penny would have to have oxygen as well for this to happen.
Coca cola will eat away at the penny because it is very acidic though. Given enough time it will eat all the way down to the zinc inside the penny. The exposure of the moisture to the zinc will then create zinc hydroxide, "white rust".
Sugar reaches the copper and they form a physical change
You should just soak a PENNY in CoCA CoLA.
no because of the carbon dioxide, it is impossible to rust
i did a science project on it and all it did to the penny was stain it but i dont know because i just let it sit in the coca cola but maybe if you scrubed it with something maybe be but i tested it and it just stained it
Coca Cola is full of acid.
Coca cola contains carbonic acid, phosphoric acid, and sugar, all of which can accelerate the rusting process of a nail due to their corrosive properties. The acidity in the drink reacts with the iron in the nail, causing it to corrode and rust at a faster rate when submerged in Coca Cola.
It may take a few hours to overnight for Coca-Cola to remove rust from a nail. The acid in the soda can help break down the rust, but the effectiveness may vary depending on the amount of rust and time left to soak.
coca cola (soda) is the best to remove anything from rust to grese grass stain excet.

It would be Coca Cola.
Coca Cola is a sticky substance when it dries, so it is not an ideal product to use for most cleaning jobs. The best to try are: cleaning the toilet, removing rust, degreasing an engine, and if you want clean pennies, you can soak them in coca cola.
Both work but Coca Cola is the best
