Sticking ur hand into the wires of a lightswitch

[chabibi]

if you live in north America you are on 120V circuit you feel a mild buzz and shock and maybe a tingle for a few minutes. you can get zapped just for fun without doing any serious damage (as long as you are not wet) if you live in Europe or elsewhere chances are you have a 220V circuit then its a painful zap which would leave the affected area pretty sore for a few hours, death or serious injury is much more likely in this scenario if you mess around.

also sticking your hand in the wire box wont do anything you need to unscrew the murret (little colour coded plastic caps) and touch where the wires meet. also wearing shoes might be a good idea
