I'm trying to recreate the system in a toy called an Energy Orb. It
was a plastic ball with a flashligh bulb (or LED)and two watch
batteries in it.  There was no on/off switch, but there were two
strips of metal on the surface of the plastic, and the light would
come on if a person touched both strips.  Or, if one person touched
one strip, and a different person touched the other, the light would
turn on when these persons touched each other.  I thought the person
was completing the circuit between the two batteries and the bulb. I'd
like to know how this worked or how to build a system that would work
this way.
