In answer to the Jacobs Ladder puzzle,  your problem is an inadequate
power supply for the length of arc your trying to achieve.  A television
flyback for a color television set produces from 20 to 30K volts which
will arc less than one inch with normal humidity.  The reason the arc's
length increases when you blow on it is the humidity of your breath 
increases the conductivity of the air through which the arc must travel
thus increasing the maximum arc length.
