While I was in Photography class in high school, we used to go into the dark room and put pennies in the fixing agent trays. The copper would attract the silver that was left behind in the trays due to the developing process. The longer you left the copper in the tray, the more silver would be attracted to it. Works with other metals as well. Hope this helps.
