capacitance of homemade caps

Original poster: "Steven Steele" <sbsteele@xxxxxxxxxxxxx>

How could I find the capacitance of my hommade caps? I can't do anything with an o-scope to measure it becaus the caps require high voltages to charge them at all. Maybe if I used a DC power supply, like a computer moniter, and set it up with a spark gap, I may be able charge it longer than .008 seconds(half the period of a 60Hz waveform), and I could time how long it takes (approximately) for the spark to break out.Do ya'll think that would work?
