I'm, uh, stunned that this myth is still being passed around. Electric current has absolutely no effect on any type of snake venom. Period. This idea has been investigated and rejected thoroughly. By the way, I am a biologist who's written a field guide to western reptiles and amphibians, so I'm not just passing on hearsay. The best way to use electric current if you're bitten by a venomous snake is to engage the starter motor to your car and get to a hospital!
