This observation shows clearly that the observed effect is the same of a
"Jacob's ladder". The hot ionized spark channel rises, because it is lighter
than cool air. Maybe it is possible to explore this effect to obtain very
long sparks, driving something as a large, well insulated, Jacob's ladder 
with a Tesla coil.
