Why Does Soaking An Egg In Vinegar Make It Bounce?


The Science Behind It: The shell of an egg is made of calcium carbonate! When the egg is placed into the vinegar, you see bubbles, which is the chemical reaction of the acid within the vinegar reacting with the calcium carbonate of the egg shell to produce carbon dioxide.

How do you turn a penny green?

When copper is exposed to oxygen, it forms molecules called copper oxide that make pennies look dirty. Pouring vinegar over the pennies helps break up this copper oxide and expose the pure copper on the penny. As the penny dries and is exposed to the air, a chemical reaction occurs and the penny turns green!
