A penny can turn green when exposed to acidic liquids like lemon juice or vinegar, which cause a chemical reaction with the copper in the penny to create a greenish patina. Saltwater can also cause a copper penny to turn green over time due to oxidation.
To make a penny green, you can simply expose it to oxygen in the air, which will cause it to oxidize and develop a greenish hue over time.
Vinegar and lemon juice are effective liquids for cleaning pennies. Their acidity helps to dissolve the tarnish on the penny’s surface, leaving it shiny. Simply soak the penny in either of these liquids for a few minutes and then rinse it with water.
Yes, a penny can rust in certain liquids that contain water and oxygen, which are necessary for the oxidation process that forms rust. Metal coins like pennies are typically made of copper, which can react with liquids like water or acidic solutions to produce rust.
A penny turns green in water due to a chemical reaction between the copper in the penny and the oxygen in the water. This reaction forms a layer of copper oxide on the surface of the penny, giving it a greenish tint.
That green stuff that shows up on copper is called verdigris, and is also known as patina. In addition to making your penny green, it's also what makes the copper Statue of Liberty look green!The process by which verdigris is made is called oxidation. Most of the time, when copper oxidizes, it turns dark brown, like most pennies you see. When saltwater is added (like in somebody's sweaty pocket) the copper turns green instead.

A green penny can turn green when exposed to the elements, like oxygen and moisture, causing a chemical reaction with the copper in the penny. This reaction forms copper oxide, which is the green coating that gives the penny its green color.

Yes, different temps will effect the amount of rust on a penny, nail, needle, and paper clip. The different types of liquids will also effect the rusting process.
