Avoid crossing the body (heart) and entering the bloodstream.

I have a book on electrical safety that goes into the risks of shock
if you really want to do research on this.

Actually, almost all of the power lost to a resistor is converted into
heat, so it's quite efficient.

Dumping a small amount of current through a nichrome wire will quickly
make it glowing hot.

I used to touch a wire to aluminum foil to complete a circuit as a kid
(using a few C cells) and it would vaporize the aluminum at the point
of contact.

Maybe you could repurpose some of those cold-weather foot warmers
(electric socks); they last a long time on a single 9V battery, IIRC.
