here is another experiment to do with fun
with chemistry. you will require silver nitrate solution and a thick copper rod. dip a clean
copper rod in silver nitrate solution. you will soon find that there would be a deposit
of silver on top of the rod. if you remove the rod you will find that it will be coated
with silver. now instead of a rod you cut a tree shape from a copper foil. if you dip
it in then silver will be deposited on this copper tree and after you remove it, it will
look almost like a silver tree. the silver nitrate solution is expensive. its a very
graphic chemistry experiment.
