Fact - Electrons do the moving, not the protons.

Experimental Fact - Compare charge on each with glass rubbed with silk

Now did I miss something?

Howdy Tap-Lers,

Here's an interesting question that stumped me the other day in
class... How do we know that when rubber and fur are rubbed against one
another, that electrons are actually transferred from the fur to the
rubber? How do we know it's not the other way around?
