First, the spheres! I'll use this picture by adapting it many times, I think.dw:1374773765719:dw

How can you introduce the same amount of charge to each, precisely? Naturally, the negative charges (electrons) will move away from negative and towards positive, you know. But there is a sea of electrons, and the electrons will disperse among themselves until they're staying as far away far away from more electrons. By that model, the electrons in the spheres would naturally move to even out the charge. But the electrons have no path to easily flow along. I mean, a high voltage will "break down" the air and electrons will jump across. But then the potential difference wouldn't be high enough to jump, but still be difference. So you give them a path  a conductor to let the electrons flow. Pretty much. connect them by a metal rod, or something.

I was thinking you can charge a glass rod with silk leaving it with a net positive charge and placing it in between the spheres, this would cause the electrons to move towards the rod thus leaving the spheres with a net positive charge.
