I like to present my "High Voltage ignited Plasma Bulb"
Step 1: The material
A Neon filled bulb (any type will do but I found out these fireballs are best)
Electronics from a disposal camera (how to modify see here: CLICK)
A potentiometer 200K
A handle for the poti (I used a foot contact of a bulb)
Some fittings made of copper and brass
A base plate made of wood
