That’s funny!
But can this be true? To trigger a blink of an eye with mini ‘electro-shocks’ to the temple, that’s possible in my opinion. You need at least 25 blinks / electro impulses for each of the eyes. That’s also feasable, I think. (I don’t know exactly if this is really enough but it has to be the minimum!) But when I try to blink with my eyes as quick as possible everything is getting dark. The amount of time I closed my eyes is bigger than the time I have my eyes open and the ‘open time’ isn’t long enough to process the content / images. So in my point of view this video is funny but not more.
