There are neon testers around which have a neon and resister inside a
screwdriver handle and a metal contact at the end of the handle.
If the blade is on a hot wire then the neon will light if you put your
finger on the other end.
The circuit is completed by the capacitive coupling of your body to the
general ground which of course is at the same potential as the neutral.
