I was watching CNN a few minutes ago and they were talking about the Democratic Convention coming up.  They were talking about how the CNN crew will be down on the floor with the delegates at the Pepsi Center, and how that is a big deal because the rest of the news crews are up in the sky boxes.  Being down on the floor will give them a unique perception of the electricity of the crowd.  That got me thinking about how many times I’ve been in a large crowd and how there really DOES seem to be some kind of electricity in a crowd.  I think it would be interesting if someone created some kind of a machine that measured that type of effect and did some research on it.
