A pile of CD’s
Attach the CD’s in place of the teslacoil’s breakout using the bulldog clip and aluminium foil.
In a well ventilated room, Turn on the tesla coil. The Aluminium is removed from the CD in a display of sparks and arcs.
Be careful that the CD does not catch fire as this produces toxic smoke, Also be careful with cheap writeable DVD’s and CD’s some of them catch fire quite easily.
