Why is it that someone who discharges static electricity feels a sting but the person who is receiving the static electricity doesn't feel anything?
Thanks
Thanks

This is called Crown Discharge and happens when the tension between two point separated by air overpasses a certain value (relatively high) then the air becomes a conductor and so the charges move trough it. The sting felt is due to the electrons them selves as they are quite energetic and kill some cells what makes you feel the little sting.
Any correctios are welcome :)
In order to kill a cell you need a certain current density. Static electricity discharges have a very high voltage, but a very low current, so they generally won't kill cells significantly.Red_CCF said:And does electrons kill cells as they arrive or leave someone

Clearly, damaging the epidermal skin layer (which is mainly dead keratin) is different from triggering a sensory nerve. Apparently, one can produce a pain sensation by applying a localized electrical stimulus (Bishop, Physiol. Rev 26, 77-102, 1946), but I don't know if the specific mechanism has yet been elucidated.
