Not exactly what you are looking for, but those clicking cigarette lighters
that use no flint contain a little gizmo that creates an electrical spark.
They are mildly uncomfortable to get zapped by. I think they make a
barbeque sparker very similar. Probably pretty safe, probably.

Hi,

I'm considering buying/building a battery-powered "zapper" that will
deliver a *mild* electric shock when the electrodes are touched. I'm
*not* looking for a stunt gun. The intended us of the zapper is for
teaching children about electricity (about electric shock, the danger of
electrocution, & how electricity can travel through conductors). Safety
is the no. 1 requirement. The "shock" should be no more painful than
from a static discharge but should be continuous (unlike a zap from

static).

Does anyone have a schematic that uses easy to find parts (available
from RS)?

(I can imagine that someone will tell me the demo is a bad idea, but I
can't think of a better way to help children understand electricity from
a safety perspective than to let them experience first-hand a mild
electric shock in a safe and controlled demo. If anyone has a better
idea, I'd be interested.)

Thanks.
