Knowing me I WOULD try it with my fingers. Not tongue though, not that crazy.
I can also confirm those cheap mosquito zapper rackets don't have a bleed resistor. Ouch. Well they probably do, but it probably takes more than a few seconds to discharge.
I was also having fun freaking out a friend by discharging it with my keys. "how are you not getting shocked?".
Speaking of high voltages, electronic mouse traps sound like a fun territory to venture in too as I do have an issue in my attic... but I rather not burn my house down if something goes wrong. lol. I could have it monitor the current and when it detects a change for a certain duration it would trigger an alarm so I know I caught one.
