with only one pole of a high voltage source when the source is not grounded in any way and their is no leakage path?

Is there an electric field gradient created through air anyway? I suppose there must be but how does the current find its way back?

I found this out when playing with a high frequency cold cathode tube inverter, you can draw sparks from one side against metal objects even when the other side is not connected to anything.

Cheers

Why must care be taken to have the reagents and apparatus completely dry when a Grignard reaction is performed? Support your answer with chemical equations.

Thanks in advance
