Default conduction

If two conductors are merely touched together electricity can flow between
them. That just seems too easy somehow. I mean, just touching? That's
ridiculous. I've always thought that it ought to need more intimate
bonding between conductors for current to flow.

No it doesnt with the lower currents.

Even if the conductors aren't touching, sometimes there's a spark.

Only if there is a significant voltage across the gap.

Another question. Why do I wonder about such things?

Thats just the Alzheimer's, nothing to worry about.
