I have put together a Slayer exciter and when holding a incandescent bulb at the high frequency output a get something that looks like a plasma flow from the filament to the glass. When moving the bulb back and forth the plasma flow wavers -- just like a waterflow from a hose would waver if i wiggled it. What makes the plasma (?) waver? It is in a sealed glass bulb, so it is hard to see what forces is are action here. Anybody?
