Don't you? I actually did it when I was a kid.But there are documented cases of people who have died after testing a 9 Volt battery on their tongue!!
I'd like to see a few of these documented cases.It is probably true that under 50volts is safe, depends on how conductive your skin is at the time, and whether the current can flow through your heart or brain. I guess that may not be a problem for some of the population as many appear not to have a brain judging by the things I see posted on youtube! But there are documented cases of people who have died after testing a 9 Volt battery on their tongue!! Guess there are always exceptions to the general rule.
That info came from a a medical program called "a thousand ways to die" From what I remember, one of the people who did it had some sort of brain seizure, went into a coma and eventually died.I'd like to see a few of these documented cases.
Were they electrocuted? Or did they fall of the tightrope they were walking on when they jerked their head up?
A 9 V battery definitely has the ability to push a lethal current through the heart and other sensitive paths, if you get past the skin resistance. But I have a real hard time believing that the current flowing through about a half inch of the surface of your tongue is going to put enough current through a sensitive path.
