Mehdi Sadaghdar posted this educational-comedy video back in April, but it has only gone viralviral now. Already, it has garnered over 425,000 views, and has been featured on DesignWorld, BestOfYouTube, SayOMG, and VideoSift

The nerd host talks about Electrostatic Discharge or ESD, a charge than can jump from humans to electronic devices and perhaps damage them. For this reason, much testing is performed during the design stage of consumer electronics. 

While attempting to show us how an ESD gun works, the host inevitably makes his educational video more of a comedy.
