This won't be easy to make safe.
One way is to discharge a stored high voltage. Something like a 10 KV
DC power supply that charges the wire through a high value resistor (50M
Ohm HV). The wire's own capacitance will store the charge. Add a few
pF if needed.
Another way is to use a radio frequency. A xenon trigger transformer
can zap a fly. This causes burns rather than shocks.
Don't kill yourself. I suggest putting all circuits on a short timer.
