> From: Brian Kraut > > I did my demonstration of a Tesla coil discharging into a metal rod in my > hand My physics teacher was demonstrating spark generation using some very big army surplus HV caps. One of his examples was to show how the spark is longer in a flame. Tip : Don't hold a bunsen burner spewing out ionised gas between two HV terminals just itching to discharge into something Clue : Plenty of ouch current can get to the metal down the flame faster than you can act on a "let go" message up your arm
