tarnish :p
The corrosion on a penny is typically a greenish-blue substance called copper oxide that forms when the copper in the penny reacts with oxygen in the air and moisture. This process is known as oxidation and can give the penny a dull or tarnished appearance.
In 1943 the US Mint briefly replaced the copper penny then in use with a steel penny, due to the wartime copper shortage.
The U.S. penny, which is officially called the one-cent coin, is made primarily of copper. It has a composition of 97.5% zinc and 2.5% copper.
Alchemy is the only way to turn a penny into silver. But post-1982 cents are zinc coated with a thin layer of copper and it is possible to remove it chemically which gives a silvery appearance. However, such a penny is NOT silver, is NOT worth any more than 1 cent.
When you put a penny in water, its density is greater than that of water, so the penny sinks. This is because the weight of the water displaced by the penny is less than the weight of the penny itself.
