Test your nerve – with electricity

Description

Initially, you may jump away from the shock when the electrical current hits your outstretched finger. It certainly smarts a bit! But the little sting doesn’t really hurt – quite the opposite. Everyone wants to know exactly where their individual pain threshold lies. One little shock. And then one more. Then just one more. But what is the real the attraction of this test? It’s certainly not a magnet. It is more likely the thrill of testing your nerve!
