To Nithika's question: remember photons of UV light "ionize" the metal in the can. So knowing this and the fact that the can is discharging, you should be able to deduce what particles are leaving the can, and hence whether the initial charge on the can was + or -.

All aluminum parts. Roll up some foil. Leaves are hanging from 30ga wire. Scrape paint off can near light.
