A basic word of warning to others: Static Electricity Generators are not a great idea in high humidity conditions (relative humidity inside was over 50%). My Van De Graaff generator experienced a mess of problems - from belt problems (thankfully I brought a backup with me), alignment of brushes and (of course) output. The size of my Van De Graaff should make discharges at least a foot long - due to humidity I could only achieve about 1/2 inch.
This years Faire was great, even with the hot and humid weather (we were all, thankfully, inside).
