My chum Jay Dowling just sent me a link to a training video on YouTube. The presenter is showing the use of an electrostatic gun to verify the ability of electronic components and products to survive encounters with electrostatic discharge.
Unfortunately, the presenter doesn’t seem to know which end of an electrostatic gun is the "sharp end," although he soon finds out...
If you read the comments associated with this video you will see that some people think this is all staged (in which case the presenter must have an unnatural fascination with self-inflicted pain), while others think his actions were unintentional, but the film's editor left them in for laughs.
And lest you think that the presenter in the above video could not possibly be as inept as he appears to be, may I invite you to watch the following video. Suffice it to say that I don’t believe anyone can watch this without wincing and exclaiming "Oooohhhh" at least once...
But back to the first video – what do you think – ineptitude of the first order or staged?

Of course you are right when it is an actual dangerous act. But I don't consider a 25kV ESD from a certified gun a danger. Like I said, you can easily pick up 25kV sliding down one of those kid's slides in the parks. I might be crazy, but not that much that I would endanger my life!
Mehdi - I understand what you are trying to do, but in viewing, this look to me to go past humorous in into dangerous, even if the ESD gun has a lower voltage than a Taser. I appreciate the value of humor in educational videos, but, personally, I'd rather see it come out in a different form.
There's a trend these days toward self-violence in videos and I don't think it's a healthy trend. Call me a spoil-sport, but when taken too far, such imagery detracts from the message. It becomes more a pure humor vehicle than an effective educational too.
Well, I don't want to admit to my ineptness! But the 25K was true and I was zapped during taking the video. But I was well aware of it and my point was to make the video funny so the message sticks! Also I should say although it hurts, the 25K ESD is not as hazardous as it sounds. A tazer gun is around 50K I believe. If you slide over those plastic slides that are held with metal screws to ground, you will definitely feel the 25K ESD down there!
Definitely, the video is staged... or the guy is trying to kill himself !!
There are several videos in youtube in which Mehdi Sadaghdar does "risky demos". Below you've some examples:
Shorcutting a huge capacitor...
Playing with car batteries...
The first part of the video seems so obviously deliberate... but when the demo-guy finally takes the charged board from the desk, almost makes me cry!!!
I totally agree with you in that the video itself is in fact very educative for ESD newcomers
