Somebody bold enough to try this project and give us the results? https://afrotechmods.com/cheap/negativeiongenerator/pikashoe7.htm
For maximum pain, zap people with an insensitive part of your hand, like your knuckle, and touch the victim on a sensitive area like their fingertips, neck, clitoris etc. .... ouch!!! what the guys says is quite possible ... though i dont know what a negative ion generator is .. :S plus i dont want people rolling me over and diggin a grave for ma toes .. anywho ... when i was a kid i rem i used to short-out the bridge rectifier assembly in an ordinary AC transformer a.k.a AC adaptor, connect the terminals with a 1.5V AA cell and zap things around me (it amplifies voltage by many times ... i think i got something like 1.5v in 45v out).. or salvage the vacum ion tube from old camera flash and do the star wars thing with it hehe ...
