On not touching the water:

I was curious about this, so I hooked up a diode and capacitor and voltmeter
and tried to measure a RF field in the water.  Nothing (I also checked the
circuitry with a RF generator and it worked).  Feeling a bit safer, I tried
touching the water and all I could feel was some warmth.  The humidifier
says to never use water > 104 F; I imagine this is to insure the water can
absorb enough energy to effectively cool the transducer.  Ideas???
