Hi Eric.
You crazy guy, you! I guess I'd challenge your definition of "super dry and cold out" here in the Great North! :-) As I sit here writing, the temp outside this morning is a balmy -15 F (-26 C) with a wind chill to about -30 F (-34 C). We haven't quite gotten to that point yet this year, but I've seen the demo done by a weatherman here where a cup of steaming coffee is thrown into the air and completely evaporates so no liquid hits the ground. Neat trick. Ever seen a Coke machine with a HEATER in it? :-) They've got 'em here.
As far as the chained class discharge deal, I seem to remember an anecdote from a TI workshop where a teacher had a student lose feeling in one arm for several days. The student recovered and no lawsuit was filed, but there is apparently some danger. I do remember making the little film can capacitors with a freshman class years ago, and watching the students (mostly boys!) compete to see who could stand the most shock without admitting pain. Ah, the joys of youth!
Enjoy!
