What are the chemical properties of copper?
Well, for one, copper forms copper oxide and copper carbonate when it's exposed to the air. That's why the Statue of Liberty has that blue-green tint to it: it's covered by copper carbonate.
I would call for help, that's the only thing, sorry. Bears run faster than humans, and they climb faster too, not to mention I have short legs. Don't think I can outrun a bear.
