Boulder once had more PhDs per capita than any other city larger than Los Alamos. I don't know if that is currently true. Both towns have become so expensive, younger scientists are priced out of their housing markets.
Anyhoo, Boulder is the place to be for science enthusiasts of all ages tomorrow, November 8, 2014.
NCAR is hosting Super Science Saturday between 10:00 AM and 4:00 PM at the Mesa Lab. People have been practicing demos all week. Come at 2:00 PM to see a ping pong ball get dropped into liquid nitrogen or to help launch a weather balloon.
The University of Colorado hosts a Mr/Ms Wizard demonstration one Saturday a month (timed to avoid home football games). Go to Duane Physics Rm. G1B30 at 9:30 AM on November 8, 2014 to watch Eric Cornell demonstrate "SPEED!"
I have past experience as a science demo performer and launching weather balloons, but I will be sitting in the audience tomorrow.
