This guy turns his microwave into a DIY plasma generator. Some matches and microwave makes science(stupidity) come to life.
Plasma Theory
“In physics and chemistry, a plasma is typically an ionized gas, and is usually considered to be a distinct phase of matter in contrast to solids, liquids, and gases because of its unique properties. “Ionized” means that at least one electron has been dissociated from a proportion of the atoms or molecules. The free electric charges make the plasma electrically conductive so that it responds strongly to electromagnetic fields.“ wikipedia.org

lol awesome… but your hypothesis is wrong. Not how it was done in my vid. But close enough.
@ Happykillmore: How is the hypothesis incorect? A quarter dipole or other dipole antenna would behave like an oscillating dipole in any E.M. field so a voltage gradient would appear across the length of the antenna. When the voltage is high at the top, the gradient implies that currents flow toward the ground plane and the voltage should also be able to reverse. The inverse behavior of voltage and current obeys electromagnetic induction I think and a spark could be made to leave the antenna at the point of high voltage if the air is ionized. I think the glowing arc counts as a plasma right?
