Guy shocks his own tongue to learn more about electricity

Summary: Sadaghdar runs around 4 volts of electricity through his tongue and slowly increases the frequency, or the rate at which the alternating current changes direction across the wire per second, to see just how painful it can get. Along the way, he plots the level of pain by raising his hand as the pain increases.....


Sadaghdar runs around 4 volts of electricity through his tongue and slowly increases the frequency, or the rate at which the alternating current changes direction across the wire per second, to see just how painful it can get. Along the way, he plots the level of pain by raising his hand as the pain increases.

Frequency creates pain by causing the muscles to move back and forth. Eventually, the pain starts to feel more like intense cramping when the frequency reaches a level where the muscles can't keep up with the vibrations.



Sadaghdar, an electrical engineer based in Vancouver, wrote on his website that when he hit the 22Hz mark, the lights in his vision started flickering because the electricity reached far enough into his head to make either his eyes or eye muscles vibrate. I'll bet Bill Nye the Science Guy never did anything like that for science.


Sadaghdar didn't just do this for a cheap laugh. He also reviewed the video and created a chart plotting the level of pain he felt at the corresponding frequencies. He wrote that he hopes scientists may be able to use the data he obtained to help make some kind of medical breakthrough, though he doesn't specify what kind. 

Well, if there are any psychologists out there conducting a study to see how far people are willing to go to get more YouTube hits, Sadaghdar's video alone should supply them with more than enough data.
