Many years. I'm no longer allowed to touch things more delicate than myself. :(

Take a look at a Van de Graf generator too.

Isolate the metal from ground, and shine a light with photon energy larger than its work function. Viola! You have a metal that is positively charged!

Next time, when you post a question, try to present it in as complete of a manner as possible. I still don't think you're telling the whole story here, and the quickest way to annoy members who are trying to help is to give them only bits and pieces of information as you go along.
