I've seen the hotdog demonstration many times and often wondered "if it's
so
great, why isn't anyone using their finger instead of a hotdog?" Now I
know.

In order to instill faith in a product, it's creator must apply a true
life scenario. He did, I'm convinced.

That reminds me of the demo the guy that invented the ground fault
interrupter circuit was to said have done.

He grabbed one hot 120V wire, with the ground in a pool, and jumped in.

Balls, in both cases.
