I did a science fair project on protecting iron from corroding using a 
sacrifcial anode of zinc(obtained from pennies - very inexpensive!). When I 
used copper with iron it accelerated the corrosion of the iron because copper 
is more cathodic than iron. Can I cause copper to develop a patina(corrode) by 
creating a sacrifical anode between the copper and a more cathodic metal? If 
so, which metal would I use?
