2002 Tri-Valley Science & Engineering Fair March 23, 2002 Over 200 individual and team projects from 20+ middle and high schools participated. For the first time, the fair offered hands-on exhibits and demos like making shrinky-dinks from plastic takeout containers and demonstrating how peddling a bicycle can generate electrical power. The Blackhawk Museum's permanent exhibit displays more than "100 historically significant and artistically inspired automobiles — mostly one-of-a-kind — dating from the turn of the century through 1991."
