Static Electricity Demonstration Goes Shockingly Wrong [Video]
ESD is short for 'Electrostatic Discharge', and this video is meant to show you how everyday electronics are protected against ESD. Instead it makes you take a few minutes to catch your breath after laughing so hard.
I don't know one person who has not drug their feet across a carpeted room, laughing to themselves the entire way. Knowing that when they reach their target, they are going to deliver a painful shock to their victim.
Imagine if everyone you know pulled that joke on you all at once, and you recorded it for everyone to see . . . now watch and enjoy.
