1 egg, 1 cup vinegar, 1 clear glass

                    1. Pour 1 cup of vinegar into jar

                    2. Add the egg

                    3. Record what you see (bubbles rising from the egg)

 

                    4. Leave the egg in the vinegar for one day.

                    5. Remove the egg and feel it.
 
 
   
  6. Record your observations (the egg shell will be soft) bag closed.

                  Eggs contain something called "calcium carbonate". This is what makes them hard. Vinegar is

                  an acid known as acetic acid. When calcium carbonate (the egg) and acetic acid (the vinegar)

                  combine, a chemical reaction takes place and carbon dioxide (a gas) is released. This is

                  what the bubbles are made of. The chemical reaction keeps happening until all of the carbon

                  in the egg is used up -- it takes about a day.
                  When you take the egg out of the vinegar it's soft because all of the carbon floated out of the

                  egg in those little bubbles.
