I just watched your video #52 where the gentleman was showing charging
a cap and then taking it apart and putting it back together again. Why
didn't it discharge when he handled it? If he had touched both plates
at the same time he would have received a nasty shock and we would all
have had a chuckle at his jumping around, after seeing that he was
alright, of course.

But he handled all three pieces of the cap including the dielectric
and didn't get any shock. Yet after putting the cap back together, he
drew a spark by shorting the plates. If the charge is held in the
dielectric, then why didn't it discharge when he picked it up. He
handled both sides of the plastic and skin is conductive, so what
gives? And would there have been a discharge if he had just touched
the jumper wire to each side of the plastic without it being
sandwiched between the plates?

I wish I had a piece of plastic laying around, I would try this
experiment and see. Knowing my luck, I would get zapped <g>.
