Suppose a properly selected plastic insulator is volume-electrified as
above and allowed to solidify. You will have a permanantely charged object
with interesting properties. For example, a positive "pith ball" of 0.001 C
and a negative one ...  And not only for classroom demos. A patentable
project anyone?

Physical reality does not have to agree with our ideas. But in physics
our ideas should agree with that reality.
